What is the Standard Bedroom Door Size?


You are here because you need an answer to the question, “what is the standard bedroom door size?” Maybe you’re thinking of replacing your current bedroom door, or in the process of picking one for your unfinished bedroom. In any case, you’ve come to the right place.

Bedroom doors, kitchen doors, bathroom doors, and stairway doors—basically every interior door in your home—have slight variations in size due to architectural considerations. Your home’s size and design ultimately determine what kind of door will fit where, and the size of your bedroom door is no different.

That said, all doors that allow passage, whether interior or exterior, must be at least 80 inches in height. The width of an interior door maybe 24 inches, 28 inches, 30 inches, 32 inches, and 36 inches, but the height must be at least 80 inches. If you or one of your family members is a person with a disability, then the minimum required door width is 36 inches.

Of course, there are many more factors to consider when choosing a new bedroom door. The size matters, yes, but if you want to make the most out of your purchase, you need to think about more than just standard interior door sizes.

Bedroom Door Buying Guide What You Need to Know

This buying guide will give you a quick but thorough insight into bedroom door types and what makes some better than others. By the end of it, you will be confident enough to make an informed decision based on not just size, but also operation style, finish, material, and design. Let’s get started.

1. Picking a door based on operational styles

When picking out a bedroom door that suits your home, don’t limit yourself to the traditional single- direction swinging hinged doors. They are the staple, no doubt, but when it comes to interior doors, your options are plenty.

We will take a look at four of the most common types of interior doors based on operational styles: French doors, pocket doors, sliding barn doors, and dual-direction swinging doors.

French Doors

French doors are popularly used for patio entryways, but they can be used as either interior or exterior doors in your home. They can easily be distinguished by their appearance, which often includes a glass panes embedded into a wood frame. Thus, French doors are great for bedrooms that need more natural light, especially in open-plan settings.

The main reason why you should consider installing French doors is that its traditional variants are usually double-hinged. That means it can open outwards or inwards, depending on the direction you’re walking towards. Though this is great for convenience, it’s not so conducive for small spaces such as bedrooms placed along hallways or adjacent to other rooms.

The upside of French doors is that they make your bedroom look bigger and are double-hinged, so they can swing both ways. French doors are also classically beautiful, and will undoubtedly enhance your interior décor if installed correctly. They are also easily customized to suit your tastes, whether it’s modern or retro.

The downsides are that they are not great for privacy, they take up a lot of space when opened, and they are more fragile compared to their solid wood counterparts. Furthermore, they aren’t energy efficient due to the gaps around their hinges. It is also wise to confirm that your home’s architectural style agrees with French doors; otherwise, they can be an eyesore.

Sliding Barn Doors

Sliding doors are great for tight spaces and areas around your home that need a little creativity. They’re effortlessly trendy and, for the most part, reasonably efficient, although there are some negatives to speak of.

Let’s start with the positives. Adding a sliding barn door is possible even with smaller bedrooms, or bedrooms placed in tight nooks. The door sort of hangs on the rack that it slides along to open or close. In terms of operability, it’s pretty straightforward. Sliding barn doors can be trendy, convenient, or cheap, depending on the result you’re looking for.

Unfortunately, such doors tend to have some unforgivable limitations. For one, a sliding barn door doesn’t shut all the way—not like a conventional door would. It will cover the entryway to your bedroom, but it won’t exactly fit inside the door frame, so there’s bound to be some gaps.

This flaw makes sliding doors incapable of blocking sound. Furthermore, you may have some trouble trying to lock it from the inside lest you opt for a flat bolt that doesn’t scratch or bump into walls. Finally, sliding doors are notoriously loud. Unless you find a relatively quiet track, you have to deal with the thundering sound they make when slid open or close. It might be annoying to the occupants of other rooms around you.

Pocket Doors

When space is at a premium, most homeowners steer towards sliding pocket doors. Unlike sliding barn doors, pocket doors disappear into a crevice or pocket in the wall. As a bedroom door, interior pocket doors work out great for small spaces, though they do have a few challenges.

The most common reason homeowners opt for pocket doors is to maximize space in rooms with limited clearance. You will likely find a pocket door installed in bathrooms under the stair or similar areas where the standard swinging door will take too much space.

Pocket doors free up a lot of wall space because they go into the wall, not hang outside it. Remember, interior doors take up as much as 36 inches of wall space when open, so you get plenty more space for furniture, storage, or art if you spring for a pocket door. Pocket doors are also more aesthetically pleasing than standard doors.

Be prepared for issues like noise and smells traversing in and out of the room for pocket doors don’t sit as tightly as standard doors. They are also not the most accessible doors for people with arthritis or otherwise problematic hands because they need to be flush against the wall.

Swinging Doors

Popularly known as restaurant doors, swinging doors are not traditionally first-choice bedroom doors for most homeowners. They are more commonly installed in kitchen areas to facilitate maximum accessibility even when holding trays of food in both hands.

Swinging doors are more suited for kitchens and other high-traffic areas of your home. Still, if you decide to get a swinging bedroom door for some reason, make sure there’s enough clearance on both sides of the room. Swinging doors may add value to your home, depending on where you place them. Rather than making it your bedroom door, consider putting it at the entryway that divides the living area from the sleeping area. Then, you can install pocket doors, French doors, or sliding barn doors on your bedroom entryways to enhance that unique look.

2. Why door material matters

Doors can be made of wood, fiberglass, metal, or laminate. Metal and glass doors are cheap alternatives to wooden doors, and they can also be quite stylish. Glass does make a door more expensive, although even the most expensive glass door is still cheaper than a solid wood door. For the sake of brevity, we will only look at wooden doors as these are the most common types of interior doors.

Solid wood interior doors

Nothing compares to the warm, natural look that a solid wood interior door provides. These are timeless when it comes to appearance, and since you have a wide array of wood types to choose from, it’s easy to get exactly what you want.

Solid wood doors can be made from expensive hardwoods like mahogany, but they look just as good when made of the cheap stuff like pine. Usually, these types of doors are made from cherry, maple, juniper, or walnut, which are relatively inexpensive and durable types of wood.

On the plus side, a solid wood bedroom door will look classy yet straightforward, and may not even cost you that much. However, solid wood is prone to warping, especially when it is exposed to high humidity or rapidly changing temperatures. Consider placing it well away from bathrooms or entryways where temperature fluctuations may occur.

Hollow-core wooden interior doors

The opposite of the solid wood door is the hollow-core door, which is the most budget-friendly wood interior door you can spring for. A hollow-core door is typically made using cheap materials like composite or plywood on the outside. On the inside, there’s usually nothing but space.

Though they are inexpensive, hollow-core doors have significant disadvantages. They don’t block noise very well, and since a hollow-core door is basically a wooden shell, it is not quite as durable as a solid wood door.

Solid-core wooden interior doors

If you want the look and feel of a solid wood door without the expense, a solid-core door is the next best thing. Like hollow-cores, solid-core doors have an exterior that’s made from plywood or molded composite. The only difference is that they are filled with wood fiber on the interior to mimic the solidity and durability of a traditional wood door.

These doors are far better at blocking noise and insulating the room than hollow-core doors. However, nothing can truly replace the durability and functionality of a solid wood door, though a solid-core door can come pretty close.

Medium-density fiberboard doors (MDF)

MDF doors are engineered from recycled wood fibers. These are the second most popular interior doors due to their relative inexpensiveness and durability. An MDF door is slightly better than a solid wood door because it is resistant to warping. That makes them excellent for bathrooms, bedrooms, and entryways.

Another plus is that MDF doors don’t have a wood grain texture. Not only are they easy to wipe down because of this, but also easier to paint than regular wood doors. Most importantly, an MDF door can be designed to look exactly like a solid wood door so that no one can tell the difference.

3. Picking a bedroom door based on the design and finish

Like windows and curtains, doors contribute a great deal to the style and aesthetics of any room. With that in mind, you should choose a bedroom door with a design that’s compatible with your current home décor.

Interior doors don’t have a lot of variety when it comes to design. At most, you will have three options: paneled, flush, and the less orthodox Dutch type.

Panel doors

The most common design when it comes to interior doors is the paneled or site-and-rail style. These are the doors that come with four, six, or eight panels engraved into their surface surrounded by a smooth frame. Most panel doors are solid wood doors. In some designs, one or two of the panels are switched out for a glass panel or a lite. This design looks good on both interior and exterior doors.

Flush doors

MDF, hollow-core, and solid-core doors typically have a flush design where they feature a smooth surface on either side. This design is also ubiquitous in interior doors, and it allows you to enhance the style of your décor using paint, stains, or wallpaper finishes.

Dutch doors

The Dutch style may not be as typical as the other two, but in some settings, it can be quite efficient. Dutch doors have two distinct halves, the top half and the bottom half. This design was created to allow air and light into the room without leaving the whole entryway ajar. The Dutch style may be rare, but it is a better way to let in natural light without losing your privacy.

When it comes to functional finishes for interior doors, you have paint, stains, and wallpapers to work with. Painted may look less natural than stains, but it does help you blend the color of your walls with your door if that’s what you’re after. You can create some pretty realistic wood finishes using stains for that natural, slightly aged wooden door look. Finally, wallpapers give you the freedom to be as artistic as you want to be with your bedroom door.

Taking Measurements for a New Interior Door – How to Do It Right

Now that you know the types of bedroom doors that are available, it’s time to learn out how to take accurate measurements of your entryway so that you get the right fit.

Step 1: Measure the width of the door using a tape measure. Run the tape from the left side to the right side of your door and note down the number. Make sure to measure the door only. Don’t include any noise insulation or weather-stripping that’s on your door. To be safe, especially if your door is old, measure the width in different places.

Step 2: Measure the height of the door. Hook the tape measure to the top corner of the door and run it down to the bottom edge, then note the number. Use a chair or ask for help if necessary. Ensure your measurements do not include the door sweep or any extra layers on the door.

Step 3: Measure the thickness of the door. Open the door so that it is slightly ajar then measure it from edge to edge. To make sure that your measurements are accurate, measure the door jamb (the door frame’s edge) as well. Though the measurements may vary slightly, you must have them both. The standard door thickness is 1.75 inches or 4.4 centimeters.

Step 4: Repeat the process to get the height and width of the entryway. This is to make sure that the replacement door will fit perfectly. Remember, always round down, not up, when measuring for a new interior door. Rounding up may lead you to a door that’s bigger than your entryway.

Step 5 (Optional): You can create a diagram to help you decide when you’re shopping for doors. Take a picture of your current door (or entryway) and note down the measurements. Also, indicate the direction of the swing, whether it is an in-swing or an out-swing. Include the thickness of the door as well. This diagram will help you choose more accurately.

FAQ’s

1. My bedroom door is smaller than usual. Is that an issue I should bring up when shopping for a door?

Absolutely. In as much as bedroom doors have a standard size of 80 inches tall by 30 -36 inches wide, these sizes are not fixed. There are smaller alternatives such as 79-inch by 24-inch doors, which are the smallest, and up to 81-inch-tall doors. Getting the size right is crucial; don’t worry about sticking to standard sizes.

2. How do I accurately measure a door that’s warped?

Measure in more than one location, then either aggregate the measurements or choose the one that’s closest to its original size. You can also use the door frame, which is less likely to warp, as a point of reference.

3. Do I need professional help to install my bedroom door?

Yes and no. Yes, because you may lack the proper tools or skills to do the job properly, and no, because door installation can be a DIY job if you know what you’re doing. Play it safe and request to have it installed if you have no idea how to do it. If you’ve done this type of thing before, or are a regular weekend warrior, then there’s not much to installing a standard wood interior door.

Final Thoughts

The standard bedroom door size is 80 inches tall and between 30 and 36 inches wide. Most architects would recommend picking the widest configuration to avoid problems when it comes to moving furniture or large objects from room to room. Still, space constraints may dictate that you go smaller, which is why doors as small as 24 inches wide exist.

Naturally, you want a door that fits, so taking measurements is crucial when replacing or installing a door for the first time. You have a lot of options when it comes to operation style, design, and material, so take your time and pick the door that works best for you.
