Q: We just purchased a home that was built in the 1960s and will be remodeling to bring it up to date. Our plans include adding some new doors, and we’re wondering what sizes will work best. Are there any standard door guidelines?

A:Congratulations on your recent acquisition of a residence! Because many older homes were built before local building rules were established and because doors were typically fashioned by hand, not all older homes have doors of the same size as one another. Doors are now available in regular sizes, and they can be found at DIY stores and home improvement centers around the country. Apart from a wide selection of regular doors, many retailers also sell a variety of alternate door sizes, which may be utilized in specific sections of the home.RELATED:Know Your Door Styles: 10 Popular Designs

There are standard door sizes and some alternates available.

Interior doors are available in a variety of standard heights, widths, and thicknesses, which are as follows:

  • Interior doors are typically 80 inches in height, according to industry standards. For doors leading from one room to another, this is the most typical height for corridor doors. Due to the fact that an 80-inch door is 6′ 8″ tall (pronounced “six-eight”), it is referred to as a 6/8 door (pronounced “six-eight”). A slightly shorter 78-inch door is also available for immediate delivery. It is referred to as a 6/6 door, and it is designated for closet and utility doors. The standard door width for interiors is 32 inches in height and breadth. For a passage door, this is the minimum width that must be met. You might also be able to locate some thinner doors in stock, such as 30 inches, 28 inches, and 24 inches in width. If you need a closet or utility door, these smaller widths are permitted by code
  • You may be able to obtain 36-inch-wide doors on hand. Wider choices that comply with the Americans with Disabilities Act (ADA) are a popular choice for homes with people who have mobility challenges. The inner thickness is 13.8 inches on average. Generally speaking, this is the most popular interior door thickness, and it is often the only one available at home improvement stores. Some businesses may have doors in stock that are 112 inches thick and 134 inches thick alternately. The walls of these are significantly thicker than the norm, and they are frequently insulated or constructed of hardwood. Interior door jamb thickness on pre-hung doors is 4-9/16 inches as a general rule of thumb. The door jamb is the frame that attaches to the wall and provides support for the door through the use of hinges. When installed in a normal two-by-four wall (which is really made up of studs that are 112 inches by 312 inches in size), this thickness is intended to provide enough insulation. The thickness of an alternative jamb is 6-9/16 inches. It is intended to be used with two-by-six walls (which are really formed from studs that measure 11 1/2 inches by 5 12 inches)

Measuring for a new door is a simple process.

The majority of the time, when purchasing a door, you’ll want one that is pre-hung, which means it comes with the frame (jamb) already attached. The other form of door, known as a “slab door,” is distinguished by the fact that it has simply the door and no frame.

Measuring for a Pre-Hung Door

  1. To find out where the sides of the door will fit when it is closed, open the door and take a measurement from the inside of one jamb tothe inside of the other jamb (see illustration). Make a note of the number
  2. While the door is still open, take a measurement from the top of the jamb on the inside (where the door would fit when closed) to the bottom of the door. Make a subtraction of 34 inch and put the result down. Flooring allowance is represented by a 34 inch deduction. Take a measurement of the thickness of the door itself and put the result down on paper. When you go to the home improvement center, make sure to have all three numbers with you.

Measuring for a Slab Door

  1. To determine the width, height, and thickness of a slab door to replace, do not measure the jamb—measure the door itself.

Choose a pre-hung door with slightly smaller measurements.

A skilled carpenter (you’ll need at least basic carpentry abilities to hang a door) may then use this method to fit the new door frame into the rough opening that was previously used to hold the old door. It’s not uncommon to have to use a few shims to get a snug fit. It is best to avoid purchasing a pre-hung door that is slightly larger in size than your old door if you are doing the work yourself. It would be necessary to remove a section of the rough-in frame (in the wall) in order to fit the door jamb, and because this would modify the load-bearing structure of the wall, it would be best left to a professional.

Or, select a slab door with slightly larger measurements.

If you’re simply changing the door and not the jamb, you’ll wind up with gaps between the door and the jamb if you get a smaller door. Instead, purchase a slab door that is somewhat bigger in size than the current door and then shave it down to the precise size of the old door. Fitting a slab door as a do-it-yourself job will take time since it needs accuracy to form the indentions needed to fit the hinges and install a new strike plate that is properly matched to the old door. While installing a slab door may appear to be less complex than installing a pre-hung door, it is really more complicated.

If you want more wall space, consider a narrower door.

Large doors may be overwhelming in tiny spaces, so if you have a limited amount of available space, a smaller door can create a cleaner aesthetic while also adding wall space. Removal of the existing door and jamb, as well as reconfiguration of the rough-in frame in the wall, is required in order for a new pre-hung door to suit the available space. This project is well within the capability of a do-it-yourselfer with a rudimentary understanding of carpentry.

Consider remodeling with wider doors if your home’s doors are too narrow.

When upgrading an older property, it may be necessary to enlarge entrances since it can be difficult (if not impossible) to carry heavy furniture through them in the first place. There are a few 36-inch doors available in stock, but your best chance is to purchase bespoke doors from a home center or building supply store.

Because the rough-in aperture in the wall will have to be increased in size, it is recommended that a professional install these doors for you. RELATED: Weekend Projects: 5 DIY Door Designs to Get You Started

You can also order a custom size pre-hung door.

If your measurements don’t quite match the normal size for doors available at the shop, but you aren’t willing to extend or narrow the existing door frame, know that manufacturers will custom-make pre-hung doors to your exact requirements at no additional cost. This option ensures that your door will fit exactly in its jamb and will open and close with ease when you do so. Using this method, you may remove the old door casing and trim, install the new door, and then replace the original casing and trim, painting or staining the new door to match the old.

Entry doors are usually 36 inches wide.

However, while a door width of 36 inches is considered excessive for an interior door, it is considered conventional for front doors. The standard height, which is 80 inches, stays the same, however, as before. Additionally, the majority of entry doors are slightly thicker than interior doors, with a normal thickness of 134 inches. These somewhat wider doorways make it easy to bring in huge appliances and furniture pieces into the house without difficulty. For two-by-four and two-by-six wall framing, standard jamb thicknesses are identical to interior door jamb thicknesses, measuring 4-9/16 inches or 6-9/16 inches, respectively, to fit the walls.

What is the Standard Door Size for Residential Homes?

When purchasing a door, there are a number of aspects to consider. Which kind of door do you prefer? Do you want a slab door or do you want a pre-hung door? Is it better to have an out swing or an in swing? Once you have obtained this information, you will need to begin measuring your results. If you don’t know what you’re doing, measuring a door and its frame may be a frustrating experience. Here are some useful measurement methods to follow, as well as some fundamental facts about typical door sizes.

Standard Size for Exterior Doors

Generally speaking, the conventional size for an outside door is 80 inches by 36 inches, which is 6 feet, 8 inches by 3 feet in length. Modern homes are increasingly being built to the length of 96 inches (8 feet), with standard-width stock exterior doors available in 30 and 32-inch widths. Some door manufacturers provide doors in heights ranging from 7ft to 8ft and widths ranging from 24 inches to 42 inches. The height of fiberglass or steel doors is fixed at 6 ft. 8 inches or 8 ft. tall, respectively, depending on the material.

  1. 80″ is the most popular size.
  2. 109″ or higher is also prevalent.
  3. The majority of the time on double door systems 32″ is commonly used in double door systems.
  4. 42″ is a standard size for newer modern homes.

Standard Size for French Doors

Generally speaking, the conventional size for an outside door is 80 inches by 36 inches, which is 6 feet, 8 inches by 3 feet in length. Modern homes are increasingly being built to the length of 96 inches (8 feet), with standard-width stock exterior doors available in 30 and 32-inch widths.

Some door manufacturers provide doors in heights ranging from 7ft to 8ft and widths ranging from 24 inches to 42 inches. The height of fiberglass or steel doors is fixed at 6 ft. 8 inches or 8 ft. tall, respectively, depending on the material. The thickness of a conventional door is 1 3/4 inch.

Standard Size for Sliding Glass Doors

A great deal of natural light enters the house through these types of patio doors. They are the most widely used and least priced form of patio door available today. This sort of patio door glides in a parallel motion, which makes it convenient for residents to enter and exit the house quickly and easily. The greatest spot to put sliding doors would be on a patio or deck, depending on your preferences. A sliding glass door is typically 6’8″ high and 6′ wide, which is the industry standard. Aside from the standard sizes of 5’0″ by 8’0″, 6’0″ by 8, and 8’0″ by 8’0″, other common sizes are 5’0″ x 8’0″, 6’0″ x 8’0″, and 8’0″ x 8’0″.

Standard Size for Interior Doors

A large amount of natural light enters the home through these types of patio doors. They are the most popular and least priced style of patio door on the market right now. Homeowners will appreciate how simple it is to enter in and out of their home when they have this sort of patio door installed. Installing sliding doors on a patio or deck is the finest location for this type of installation. A sliding glass door is typically 6’8″ high and 6′ wide, which is the industry standard dimension. Aside from the standard sizes of 5’0″ by 8’0″, 6’0″ by 8, and 8’0″ by 8’0″, other common sizes include 5’0″ by 8’0″ and 6’0″ by 8’0″.

Standard Size forCloset and Utility Doors

Generally speaking, utility and closet doors have narrower passageways than conventional doors. Doors in homes built prior to 1990 might be as small as 18 inches in some instances. Newer models are typically 30 inches wide and 96 inches tall, with a standard width of 30 inches.

How to Measure your Door Properly

If you want to replace a door that you already have, take measurements from top to bottom of the present door. Continue by taking measurements from the left to the right side of the door. In addition, you should take note of the thickness of the door. The majority of doors have a thickness of 1 3 4 inches. It’s important that your door doesn’t deviate much from that measurement. The width of the door jamb as well as the height and breadth of the frame are equally vital to take into consideration.

The next step is to increase the width and height of the door by 2 inches, respectively, to allow for a proper entryway opening.

Whether or whether you are utilizing a pre-hung door, you will need to take a rough-in measurement.

Standard Interior Door Size (Dimensions Guide)

Listed below is our standard interior door size chart, which includes the most often seen door dimensions for the bedroom, bathroom, and closet. The height of the door is the most common measurement for this type of door. All internal doors that will be utilized as passageways between rooms should be at least 80 inches in height to provide proper ventilation. (6’8) This provides enough space for the great majority of individuals to pass through the doorway without hitting their heads on the door jamb.

Closet and utility doors, which are rarely utilized to transport people between rooms, can be made shorter to accommodate this need. Closet doors are commonly installed at a height of 78 inches (6’6″).

What Is The Standard Interior Door Size?

The standard widths for various types of interior doors can range anywhere from 24 inches to 36 inches in width. Interior doors are typically 32 inches wide, which is the most common width. As a result, the conventional internal door dimension is 32 inches wide by 80 inches high. The majority of individuals are able to pass through a doorway of this size without brushing up against the edges of the frame. The width of each door in your home must be at least 36 inches wide if you want to make it wheelchair accessible.

Standard Interior Door Thickness

Interior doors are typically 13/8″ thick, which is the most common thickness. There are a variety of door thicknesses available, including 112″, 158, and 134″. Oversized or extremely huge doors (those that are more than 90 inches tall or more than 36 inches wide) are often thicker than standard-sized doors. They are also more expensive. When selecting door hardware, such as doorknobs and hinges, the thickness of the door becomes crucial to take into consideration. Fire doors are also thicker than conventional interior doors, making them more resistant to fire.

How to Measure a Door

Doors are one of the finishing touches that may be added to a new building project, but you shouldn’t put off thinking about them until the very end of the project. During the framing phase, it is determined what size the door will ultimately be. In order to create a ‘rough opening’ between rooms that is sturdy enough to hold a door and door frame, contractors install studs between the rooms. The general rule of thumb for rough openings is that they should be two inches wider than the door that will ultimately be put in them.

  1. When it comes to height, the rough opening must be at least two and a half inches higher than the door it is intended to accommodate.
  2. Once you’ve created a rough opening, the next step is to build a door frame and hang a door, or you may install a pre-hung door that has already been installed.
  3. Professionals recommend that you measure the entryway (the aperture through which the replacement door will hang) rather than the existing door when determining the suitable size for a replacement door.
  4. You’ll also need to figure out what kind of thickness you want your replacement door to be.

Door Width and Height

If you want to know how wide the door you will need to order is, you should stand in front of the existing door and wait for it to open away from you. Open the door, and prop it open if required, to avoid getting your fingers pinched in the hinges of the doorframe. Measure the distance across the door opening with a tape measure by placing one end against the inside of the door frame and the other end against the outside of the door frame. A parallelogram should be drawn between the tape and the floor.

Your new door will be ordered based on the first measurement you take, which will be the largest of those three measurements.

As you would when measuring the width of a door, stand in front of it and open it away from yourself.

Both of these measures should be precisely the same as one another. It is recommended that you seek expert advice if the differences are significant, since this might suggest an underlying structural problem.

Door Thickness

You may utilize the current door to take the final measurement, which is the thickness of the door. Mark off numerous spots along the border of the door where you want to take measurements with a tape measure. This is especially crucial if you plan to reuse the hinges or door knob, as these pieces of hardware are built depending on the thickness of the door and must be installed correctly the first time.

Interior Door Sizes

Buildings of one or two stories, as well as townhouses, are subject to standardized criteria of safety and accessibility under the International Residential Code (IRC). In addition to any applicable municipal codes, this is what the home inspector will refer to when he or she comes to sign off on your new house. While there are severe criteria for the main entrance to a property, there are no such rules or regulations for inner doors. Where they are present, all that is required is that they be in excellent functioning condition and that they are installed in accordance with manufacturer’s specifications.

Standard Bedroom Door Size

There is no standard size for bedroom doors because they are all different sizes. Interior doors are typically 32 inches wide and 80 inches high, much like the rest of the house. The normal thickness is 1 3/8″ in diameter.

Interior Double Door Sizes

In a room or corridor, double doors are two doors that hang next to one other, forming a double-wide entrance or exit. Double doors are typically available in three widths: 60 inches, 64 inches, and 72 inches. The normal door height of 80″ continues to be in effect. An internal double door does not have a standard thickness since there is no standard width. The greater the height and width of the door, the greater the thickness of the door required to sustain its own weight. The dimensions of both doors must be the same in terms of width, height, and thickness.

Standard French Door Size

A ‘French’ door is comprised of a thin/light frame that surrounds panes of glass in a symmetrical pattern. The panes of glass generally account for the vast bulk of the door’s total floor space. They are frequently, but not always, hung in groups of two. If the doors are to be hung in pairs, they must be the exact same size and thickness. A French door does not have a set door size since they are made to order. There are several sizes of French doors available, with the lowest measuring around 30 inches and the largest at 72 inches.

Standard Closet Door Size

Neither the International Residential Code nor the International Building Code regulate or standardize closet doors. The size of the rough aperture is the sole constraint on the design. In most cases, closet doors are 30 inches wide by 80 inches high. Bifold doors are commonly found in closets; instead of swinging out into the room, these doors fold in on themselves instead. The typical width of a bifold door panel is 24 inches wide. More information about closet door sizes may be found here.

Standard Bathroom Door Size

A bathroom door must comply to the same basic size requirements as any other interior door in order to function properly.

It should be at least 80 inches high and 24 to 36 inches broad to be effective. The thickness and design of the door should be in harmony with the design of the door frame.

Standard Front Door Size

It is important to note that a front door is an external door, which means that it connects the inside of your property with the outside. A house’s main entrance must be at least 80 inches tall and 36 inches wide in order to comply with the International Residential Code. (Side doors and back doors can be narrower in width; the most frequent widths for these doors are 28″, 30″, and 32″ in width.) Exterior doors also have the extra job of protecting your property from the weather and keeping the temperature inside your home consistent.

Typically, the thickness of a normal front door is 13 inches.

Interior Door Sizing Considerations

Making selections concerning interior doors is difficult since you will be forced to live with the consequences of your decisions for the duration of your ownership of the property. The process of going back and making a doorway larger or narrower is difficult and time-consuming; yet, it is sometimes necessary. All of the inside doors in your home should be of the same style and design to avoid confusion. If you have a doorway that is not conventional, be sure that the door you choose is available in all of the sizes you require.

If you want to live in your house for the foreseeable future or currently have mobility issues, consider making all of the doors 36 inches wide.

Lastly, take into consideration the finish of your inside door.

Two coats of priming followed by two coats of paint can add as much as 1/32″ to the width of the door on either side of the threshold.

Standard Door Frame Size

Because you’ll have to live with the outcomes of your judgments for as long as you own the house, it’s difficult to make decisions concerning interior doors. The process of going back and making a doorway larger or narrower is time-consuming and complex; yet, it is sometimes necessary. You should have a consistent style/design throughout all of your interior doors in your property. Choosing a door that is available in all of the sizes you want is especially important if you have non-standard entrances.

It is recommended that you make all of the doorways 36 inches wide if you expect to grow elderly in your house or if you presently have mobility issues.

Lastly, take into account the finish of your inside door.

Painting the door with two coats of priming and then two coats of paint might add as much as 1/32″ to the width of the door on each side. This is something you should discuss with your contractor since it may have an impact on the size of the rough opening that will be required.

Prehung Door Sizes

Pre-hung doors are pre-hung doors that have previously been attached to a frame with hinges. The frame of the door just has to be hammered into the studs around the rough opening, and then the door is ready to be completed with molding. This method is quite popular among do-it-yourselfers, and for good reason. Hanging a door requires a certain degree of patience and skill, and even experienced pros might find it difficult at times. Purchasing a pre-hung door eliminates all of the guessing and requires no special skills.

They are normally available in two basic widths — 30 inches and 36 inches — depending on the manufacturer.

Selecting an Interior Door

Interior doors can be basic and unadorned, or they can be ornately designed. Choose a door that complements or enhances the architectural style of your home, rather than one that matches or enhances the present dcor of your home. Tastes vary with time, but doors are built to last a long time and are seldom replaced, so you want to pick a decision that will look excellent for many years to come. When considering doors, three factors should be considered: materials (what the door is made of), functionality (how the door will be used), and cost (remember to include in both materials and labor costs!)

Door Materials

Wood is the most popular material for interior doors, and it is also the most expensive. The cheapest doors feature a hollow core and are made of wood or fiberboard, which makes them the least costly. Solid wood doors are also available upon request. Glass, stainless steel doors, fiberglass, and aluminum are some of the other materials that may be used for doors. The material and design of your door should be complementary to the overall look and feel of your house. Consider the following example: A sleek, fiberglass door might be ideal in a modern home, but it would appear out of place in a more classic cottage setting.

Door Functionality

When selecting a door, keep in mind the function it will perform in your home. Doors serve as a visual and physical barrier to a space, as well as a means of maintaining privacy. These materials can also be used to produce sound isolation and dampening. This is one of the reasons why many homeowners prefer to install stronger doors in their bedrooms or home offices. Consider how you want the door to open and close. Is it better to have it open into the room or out? Should it be hung on the left or right side of the door frame, depending on your preference?

Does there appear to be enough space to the side of the rough opening to allow the door to be completely opened in that case?

Because it reduces the likelihood of colliding with someone walking by, interior doors that link a room with a corridor are often opened into the room.

When an internal door links two rooms that are not connected by a corridor, the direction in which the doors swing is dictated by the convenience of the users.

Door Cost

For a single door, you may anticipate to pay between $50 and $500 for the door frame and hardware. It is simply your time that will be extra expensive if you do the hanging yourself. In the event that you hire a professional to install it, you may anticipate to pay between $100 and $300 per door, depending on your location and the intricacy of the door in question. Pre-hung doors are often somewhat more expensive to purchase than unfinished doors, but they can be less expensive to install.

What Are Standard Interior Door Sizes?

Whether you’re building a new house or investing in a renovation project, there are several considerations to make before purchasing any building supplies or materials. Furthermore, selecting the right door form, color, and design can be a difficult undertaking, especially if you have a specific style in mind. Even with all of the factors to consider when purchasing a new residential door, there is one more element to consider that you may not have considered: the conventional interior door sizes.

The space where the door will be put must first be measured once you have decided on the color and form that you want to use.

As a result, we’ve put together this list to show you some of the most common interior door sizes that you’re likely to encounter while working on your project.

How to Properly Measure Your Interior Door

Before we get started, let’s go through how to properly measure your standard interior door dimensions. Typically, an inside door may be found in a bedroom or bathroom. You may be able to install an inside door between rooms or at the top of a stairway in some situations. When measuring an interior door, there are several common principles that will always be followed:

  • Standard inside doors must always be at least 80 inches tall, if not more. Based on the size of the doorway and the materials you want to use, a standard width can range from 24″ to 36″ in width. It is recommended that the minimum width of a doorway be 36 inches when creating an accessible entryway.

When it comes to the thickness of the door, it might vary depending on the material you use to construct it. While the majority of interior doors are 1 3/8 inch thick, there are those that can be thicker if the door’s height and breadth are very large.

Additional Considerations Before Starting Your Measurements

Whenever you’re replacing a door in an existing doorway, you’ll want to take extra steps to ensure that all of the door’s components are accurately measured. A decent rule of thumb is to start from the top and work your way down, being sure to measure everything along the path. This comprises the height, breadth, thickness, door jamb width, and the size of the frame you intend to replace, among other things. When acquiring a new door from a vendor or manufacturer, you will almost certainly be required to give the measurements in advance of the purchase.

As previously said, you must be certain that the measurements you provide are accurate since the newly manufactured door will need to fit into the old entryway. This is important since you do not want the merchant to deliver you the incorrect size!

Standard Interior Door Sizes

The majority of internal door sizes may be matched to the sizes of external doors (the front door of your house, for example). Having said that, the majority of interior doors are sized in accordance with the conventional interior door sizes listed above. If your door is wider than 36 inches in width and taller than 90 inches, it is deemed to be bigger than the norm. In such scenario, a thicker door (about 1 34 inch thick) is also advised. When you invest in a renovation project, you often have a certain amount of latitude when it comes to adjusting the door heights in the various rooms of your house to your liking.

  1. The width of your entryway is a measurement of the horizontal space available.
  2. The most significant criteria that should be observed is the height requirement.
  3. Because conventional interior doors are commonly referred to as 6/8 doors, they measure 6 feet and 5 inches in length and height respectively.
  4. When installing new hinges and doorknobs, it is especially important to consider the thickness of the material.

Interior Double Door Sizes

An exquisite addition to your master bedroom, dining room, or living space may be achieved by installing inside double doors on the inside. Furthermore, double doors are always identical in terms of width, height, thickness, and design when they are installed side by side. Due to the fact that everything must be measured twice when measuring a double door, you must exercise particular caution when measuring one. In addition, the frame will be measured differently. For double interior doors to function properly, the frames must have two sides and a space in the centre to allow for separation of the doors.

It’s critical to understand that your measurements must be as exact as possible in order for these types of doors to be placed correctly and efficiently.

The following are the most typical widths for internal double doors, according to the manufacturer: Following the normal indoor height of 80″, this is consistent with the industry.

Interior Bedroom Door Sizes

Bedroom doors are a little more fascinating than other basic interior doors since they do not have a particularly set size like other standard interior doors. Making a customized bedroom door does not require adhering to any certain specifications or rules of construction. Instead of concentrating on standard measures, you should concentrate on the overall architectural direction of the home in this instance. However, if you opt to select a manufacturer that currently has doors in stock, you will be able to choose from a set of standardized sizes.

You may discover things in store that range in size from 24″ to 36″ in length. Furthermore, while 80″ is the standard height for bedroom doors, you may easily install a door that is higher or lower than that. Many homes have inside bedroom doors with measurements such as 79″, 81″, and so on.

Interior French Door Sizes

French doors are always in high demand in traditional country-style homes. These are double doors that are completely mirror images of one another, opening in opposite directions from one another, and are frequently used as a divider between rooms or as a connection between the kitchen and the garden. In most cases, one of the doors has a handle and lock, while the other contains movable hardware elements that allow the door to open and close independently. French doors, particularly those that lead to an external space, are typically 80″ tall by 36″ wide per door, according to industry standards.

Interior French double doors are typically 1 34 inch thick, which is the industry standard.

Interior Door – Rough Opening Sizes

First and foremost, you must ensure that the rough opening for your newly-measured and custom-built internal door is the proper size before proceeding with the installation. This is the stage of the door installation procedure that most homeowners and do-it-yourself enthusiasts find frustrating. When it comes to measuring the rough opening in order to correctly prepare it for the door frame, it might be difficult if you aren’t aware of the measures that should be taken. Remembering how to structure your rough introduction is actually rather straightforward if you follow a basic rule.

You will need an extra 2″ for width and 2 12″ for height after you’ve measured the width of the real door to get the measurements you need to correctly set up your rough opening.

Size of Door Size of Rough Opening
24” x 80” 26” x 82 ½”
28” x 80” 30” x 82 ½”
30” x 80” 32” x 82 ½”
32” x 80” 34” x 82 ½”
34” x 80” 36” x 82 ½”
36” x 80” 38” x 82 ½”

You should also consider how to measure entrances that are narrower or more irregular in shape. Doors for closets and utility shelves, for example, are frequently narrower and thinner than other interior doors on the same level. Modern utility doors are around 30 inches wide, but if you have an internal door that is more than 30 years old, it may be as thin as 18 inches in thickness. Closet doors are typically 96″ in height, which is normal.

Standard Door Size

Are you contemplating the installation of a door in your residence or place of business? Perhaps you are planning a home improvement project that will include the installation of a new door.

Alternatively, you may require the replacement of a damaged office door. It is critical to grasp typical door sizes, door measurements, and the construction rules that regulate them, regardless of the situation. You could be pondering things like the following:

  • I’m curious about the normal door sizes. How do you determine the size of a door? What is the normal size of an external door? What is the normal size of an inside door? In what dimensions are typical doors measured? What is the normal height of a door frame
  • What size door should you use for your entrance
  • What is the normal size of a door jamb

Different door types, such as interior doors, exterior doors, barn doors, French doors, pocket doors, and entrance doors, all have a range of sizes to accommodate different applications. The appropriate door size for your requirements might vary depending on the structure of your building or house as well as your individual circumstances. In order to calculate the width and height of a door while replacing or installing a door, you must first measure the size of the door opening. Before choosing on a replacement door or making any adjustments to your present door frame and door size, you should take the door jamb, the door frame, and any applicable building codes into consideration as well.

Standard Door Size

Choosing between a pre-hung door and a door slab is an option if you are replacing or installing a new door to your residence. A pre-hung door contains the door itself, the door hinges, and the door frame, making it a fantastic alternative for replacing a whole door and frame set at the same time. A door slab is a door panel that does not contain the frame, hinges, or hardware; it is the most cost-effective option if you simply want to replace the door panel and leave the other components intact.

There are a variety of door sizes available to choose from.

The usual door height in both commercial buildings and residential residences is 80 inches, which is the height specified by most building rules in most jurisdictions.

Standard Exterior Door Size

The International Residential Code determines the dimensions of outside doors (IRC). In accordance with IRC building rules, external doors must be a minimum height of 80 inches to be functional. Exterior doors are normally 3 feet wide and 80 inches high, with a conventional height of 80 inches. Front door, rear door, garage entrance door, and fire/security doors are all examples of external doors that can be found on a house or building. Exterior doors in contemporary homes can be much higher, with a maximum door height of 96 inches possible.

The normal exterior door thickness is 1 3 4 inch.

Most of these doors are 80 inches tall and 6 feet wide on average—but there is a broad range of door width widths available to meet your demands, ranging from 60 inches to 96 inches in width, depending on your needs.

Standard Interior Door Sizes

The International Residential Code (IRC) also dictates the size of inside doors. Interior doors are not needed to be as huge as the main entry door, but they must be at least 80 inches in height, just like an exterior door, in order to be considered functional. Inside interior doors, such as a bedroom door, bathroom door, pocket door, and barn door (except a closet barn door), are most commonly found in three widths: 28 inches, 30 inches, and 32 inches. However, you may get them in a variety of other widths as well, including 36 inches.

Closet doors are thinner than ordinary interior doors and are not needed to comply with the same building requirements as standard interior doors.

Bi-fold doors are typical closet door designs that have two panels for a single door and four panels for double doors. Bi-fold doors feature two panels for a single door and four panels for double doors. Bi-fold doors are available in a variety of sizes to meet your specific requirements.

Standard Commercial Door Sizes

The International Building Code (IBC) regulations and the Americans with Disabilities Act (ADA) standards are used to define the size of doors in commercial buildings. People must be able to enter and escape a building in an emergency situation, thus these construction regulations regulate the maximum and minimum height and width of doors to guarantee that they can do so safely. With a few exceptions, the International Building Code requires commercial building doors to have a minimum of 32 inches wide and a maximum of 48 inches wide.

The ADA construction rules additionally include additional criteria that specify the door surface as well as the knobs, locks, pulls, latches, thresholds, and closing speed of the door.

How to Measure a Door

Before you can replace a door in your house or building, you must first measure the width, height, and thickness of the existing door in order to determine the right measurements for the new door you will use. In the event that you are replacing your present door with a slab rather than a pre-hung door, these measurements will suffice to ensure that you get the right size. Also, remember that when measuring doors, the panel is taken into consideration, not the frame or the aperture. Measure the height and breadth of your door from top to bottom to calculate the height of your door, the width of your door from left to right to determine the width of your door, and the depth of your door to establish the thickness of your new door.

Find the width of the door jamb by measuring the top, middle, and bottom of the frame’s interior, and the height of the door jamb by measuring from the floor to the top of the door jamb.

Standard Door Frame Size

You must first identify the size of the rough aperture before proceeding with the installation and building of a new door. Using this method, you may properly install a prehung door, which includes the frame, or you can cut your own rough opening to make your own frame if you like. A new rough opening may be necessary to accommodate a larger door, particularly when upgrading from a single to double door or when building an additional door where there was previously none. If you have the room, you may want to consider doing so.

With the additional 2 inches in width and height, your door and door frame will be absolutely plumb, level, and square, and your wall will be able to expand and contract in response to changes in weather.

Standard door sizes range in width from 24 to 36 inches, but the majority of them are 80 inches in height.

A rough opening of 32″ x 82 12″ will be created by a door that measures 30″ x 80″.

Take measurements from the floor to the header on all three sides of the aperture to get an approximate opening height. The smallest dimensions on the exposed drywall or sheathing can be used to determine the thickness of the wall structure.

Standard Door Sizes

When installing a new door, there are a few procedures that must be followed to ensure that you have the exact measurements for the door. First and foremost, you must choose what style of door you require. Want to replace your old door with a new one that is the same size as your old one? Alternatively, you may choose to replace your old door with a larger one—for example, by upgrading from a single door to a double door. You might also modify the function and look of the door by replacing it with a pocket door or a sliding barn door instead of a normal door.

  • If you’re replacing your door with a larger one or changing the function of your door, you’ll most likely need to make adjustments to the size of your rough opening as well.
  • You may even choose to have a bespoke door made for you.
