Bedroom Door Dimensions (Here Is What I Learned!)

Changing your bedroom door can be a quick way to change the feel of your room or have it match your chosen aesthetic. If you’re thinking of trading in your current door for another, it’s important to know your bedroom door dimensions.

The proper bedroom door dimensions are one of the most important factors you’ll need to consider. Let us tell you all you need to know and the aspects to take into account to find the perfect bedroom door for your home.

How Much Does a Bedroom Door Weigh?

Bedroom doors vary in weight based on the material they’re made from. Lightweight bedroom doors can weigh as little as 20 pounds while heavier ones can weigh over 80 pounds.

If you prefer a more lightweight option, you can look into hollow core doors. These feature a honeycomb interior made from cardboard that is encased in fiberboard or veneer. These can easily be handled and installed by one person.

If you’re looking for a highly durable and solid bedroom door that provides better sound insulation, you’ll want to take a look at heavier solid core doors. These types of doors have a solid center made from wood and synthetic wood composites. 

Both are cost-effective and popular options for bedroom doors. Other types of doors you can consider are solid wood and MDF or medium-density fiberboard doors which are both on the heavy side. 

How Do I Find the Weight of a Door?

To get the door’s weight, multiply the door’s density, height, width, and thickness and divide it by a million. Expressed as a formula, it reads:

Door weight (kgs) = density x height (mm) x width (mm) x thickness (mm)


The weight of the door is best determined after you know the weight restrictions of the hinges and fittings. 

You can also examine the door by tapping your finger on it to check if it’s solid or hollow. This will give you a rough idea of its weight.

If you want to find out the exact weight, you can also remove the door and weigh it.

How Much Weight Can a Bedroom Door Hold?

Typical interior doors like the ones in your bedroom can support between 45 to a hundred pounds. Of course, exterior doors which are usually more solid and heavy can hold heavier weights — up to 400 pounds while commercial-grade doors hold even more.

When considering how much weight a door can hold, you should also take a look at the door hinge. What types of bolts are holding it in place? If you have small short bolts, then you may have to replace them or choose a lighter door.

To examine the length of the bolts, loosen one of them from the hinges and examine if the material it’s attached to is sturdy enough to hold the weight of the door you want to install.

How Wide Should a Bedroom Door Be?

The standard widths for doors used inside, including bedroom doors, are 28, 30, and 32 inches. The International Residential Code (IRC) has helped establish this as the norm by requiring external doors to be no less than 32 inches wide.

Despite this standard, numerous apartment and old residential spaces have doors that are narrower than 28 inches and wider than 32 inches. 

If someone in your household has disabilities, aim for a door that is at least 36 inches wide.

When deciding on how wide your bedroom door should be, consider the size of the furniture you’ll be moving through it and other ways you’ll be using it. 

How Tall Is a Bedroom Door?

Bedroom doors must typically be 80 inches in height, at least 24 inches wide, and a third of an inch thick.  You’ll find that most internal doors have roughly the same dimensions. 

Most interior doors will have the same opening widths. When in doubt, it’s best to check with your contractor to make sure you get the right size and functionality you need from your bedroom door. 

Non-Standard Door Heights

The standard thickness for interior doors is 1 ⅜ inch. The bigger your door, however, the thicker your door needs to be. If you have a door that is higher than 90 inches or over 36 inches wide, you’ll need to get a slightly thicker door to compensate for the added size. For slightly bigger doors with the dimensions just mentioned, look for a door that is 1 ¾ inch thick. 

When You Have High Ceilings

If your home has beautiful high ceilings, you’ll need to consider having taller and bigger doors. After all, a high ceiling with standard-sized doors will look awkward and won’t match the aesthetics that such ceilings offer.

The best thing to do if you need interior doors with unusual dimensions is to consult your contractor or builder so you can be sure you’ll have a door that is not just beautiful but structurally sound as well.

Additionally, you can also tour homes with high ceilings for ideas and inspiration.

Are Bedroom Doors Standard-sized?

While there are general guidelines on the width, length, and thickness of bedroom doors, their dimensions aren’t set in stone. As mentioned earlier, you can have non-standard door sizes based on your preferences and your home’s unique features like vaulted ceilings.

Just be sure to consult an experienced contractor before selecting and purchasing a door to make sure that the door can be properly supported and can be used as intended.

Factors Affecting Bedroom Door Dimensions

There are many reasons why you might have different sized doors:

  • Your space is larger or smaller than usual.
  • The door should suit the type of home you have and its aesthetics. If you have higher ceilings, you’ll need to consider larger doors.
  • Your bedroom door should be adequately sized to accommodate the height and needs of the people who will be passing through the door. 
  • It should be big enough so that the furniture you’re planning to put in your bedroom can pass through.

Alternative Bedroom Door Dimensions for Smaller Homes

In situations where your home may not be able to accommodate the standard size, you can look at doors that are 78-inches in height. Also known as 6/6 doors, this type of door is generally used for closets and as utility doors.

If your door is made from hardwood, you can consider a door thickness ranging between 1 ½ inch to 1 ¾ inch. 


As you can see, there are many factors that go into selecting the right door. You need to consider the weight that the doorway can support, the weight and size of the door itself, who will be passing through it, the size of the furniture that will need to fit through it, and the aesthetics of your home. 

By taking the time to learn about how to find the right door, you can make a better decision, ask your contractor relevant questions, and be a step closer to having one of those gorgeous homes you see in interior design magazines.
