Standard Bedroom Door Size: Dimensions Guide And Types Of Interior Doors

Are you in the process of remodeling your home and looking to install a new door or to replace an existing door? The standard bedroom door size is your complete guide on everything you need to know about the standard width and standard height of interior doors such as bedroom, closet and bathroom doors. It is important to have a good understanding about the different dimensions for interior doors because changing them later will cost you money, time and is sometimes impossible. Therefore, careful planning is needed when deciding on the style, type of material and most especially the door dimensions that you are going to use to avoid making unnecessary changes. Remember, the right door size will provide a safe passageway for you and your loved ones within the home and it also provides a rescue opening in case of emergency situations.

To achieve a cohesive look, all interior doors should have the same design or style, although you can use a barn door to cover your pantry is a very nice exception to the rule. If you want to save money, pick a door style that comes in various sizes. This will help you save some money because custom doors are not cheap. To achieve a cohesive look, choose a paint color for your interior that matches with the color scheme of your entire home decor. To learn more about door paint color ideas, click here!

Afterwards, you also need to decide on what type of finish that will be best for your door. Depending on the type of material, choose a recommended finish to prolong the beauty of your door. However, this may affect the size of the rough opening that is needed if it happens that you prefer to have two coats of primer and two coats of paint. Therefore, it is important to relay this information to your contractor.

Below are the standard bedroom door sizes and other types of interior doors that you can choose from:

Standard Bedroom Single Door Size

  • Height of the interior doors when used as interior passage doors should be at least 80 inches. This provides enough room for most people without hitting their head into the frame.
  • Width of interior doors is 32 inches and with a typical thickness of 1 3/8 inch thickness.

However, if you want your single door to be accessible for wheelchair users, choose an interior door with a width of 32 inches (minimum width), up to 48 inches (maximum width) and with a height of at least 80 inches.  For hallways it should be at least 36 inches wide, these numbers are set by the ADA (Americans with Disabilities Act).

Utility And Closet Doors

  • Actually there are no regulations with regards to the sizes for utility doors and closet doors. However, these often have a height of 78 inches, shorter than the door height used as a passageway and with a width between 24 to 36 inches, where 32 inches wide with 80 inches tall is the most common sized doors for residential homes.

The closets in our master bedroom have narrower doors and what our contractor did is use the basic doors and then he customized the size by reducing its width that would fit into the opening in order for us to avoid using custom one. Results were pretty different than expected. It gave the closet doors an interesting design which makes them unique and I like it but my husband was critical about it.  Again, if you think that this will not work for you, there is always the option to buy a custom door.

Bedroom Double Doors Size

  • It usually comes with a width of 60, 64 or 72 inches and in a height of 80 inches and with no standard thickness. However, the taller and wider the door is, the thicker it will need to be. This is to provide enough support for its weight. Both doors should have the same height, width, and thickness and should open in the same direction.

French Doors

  • There is no standard size for interior French doors. They usually have a thin frame around the glass panes that covers most of the entire door’s surface area.

They are typically 36 inches wide and 84 inches tall and 42 inches wide and 80 inches tall. Its standard dimensions are wide enough to overlap with the basic size of 36″ x 80″ by one inch or more.

Pocket Doors

  • They are commonly seen in older homes but if you have a space problem, this type might be a perfect fit for you. They are ideal in a home with tight spaces where having a swinging door is not possible. Just like barn doors, interior pocket doors are ideal for space where a basic hinged door could be a hindrance which is a common problem in the bathroom, closet, laundry room and even bedroom. Standard sliding pocket doors are the same as regular hinged doors and usually come with common widths between 30 and 36 inches and with a height of 80 inches. However, it is important to take into consideration the overall requirements to install a pocket door, it usually requires a width between 51 to 162 inches and with an overall height of 86 inches or more.

Door Frame Standard Size

They are the wood pieces on which the door is fitted and installed in the rough opening to support the door. It is where the door is hinged and typically comes in the dimensions of 36 inches wide and 80 inches tall (in the United States).

Prehung Door Sizes

If you want to buy a door that is already attached to the frame, choose a pre-hung door. It makes a not so easy door installation for a non-professional carpenter (also known as DIYers) much easier. The frame just needs to be nailed into the studs around the rough opening and then beautifully finished with trim around it. These usually come with a standard height of 80 inches and with a standard width of 30 and 36 inches. However, they are also available in various sizes but they are not common.

Standard Bedroom Door Size

When we renovated our fixer upper home, changing all of the house doors including exterior doors, the front and the side door, bedrooms and closet doors were part of the renovation plan. Our contractor suggested that we replace all interior doors with prehung one because installation is much easier and therefore cheaper to install. So we did what our contractor suggested and we painted all  with extra white color paint by Sherwin Williams.

How To Choose An Interior Door

Choose one that matches the style or enhances the architectural style of your entire home. As much as possible, do not choose interior door design and style based on your current home decor because your taste for home decor is most likely to change over time. However, doors can last for a long time and are not usually easy to change and most of all, it can cost a lot of money to change one. Choose doors that have a style and design that display timeless beauty so they will look good even if your taste of home decor changes. Also consider its materials, function or how it will be used and cost. Custom doors and complicated installation means more money.

  • Materials

The economical choice are those with a hollow core and that are made from constructed wood or fiberboard. If budget is not a problem, a solid wood door will be a great one. Other door types include glass, stainless steel, aluminum and fiberglass doors.

Door materials can also have an impact on the overall style of your home. For example, the clean lines of a fiberglass one is perfect for a modern home but could be an eyesore in a traditional cottage style home.

  •  Functionality

When choosing a door, consider how you would want it to function. If you want to provide sound isolation and dampening, then thicker ones are perfect doors for your home. However, if you prefer not to have a swinging door, a sliding, barn or pocket door may be a great option for you.

  • Cost

The usual cost for a single door (depending on the design and style) is between $50 to $500 and an additional $100 to $300 per door if you are hiring a professional to install them for you. Pre-hung ones are usually expensive but the labor cost will be cheaper.

Guide To Ordering Doors

Below are the basics that you need to know when ordering a one for your new construction or remodeling project.

Know The Door Size

  • Measure your door size by determining the width and height.
  • If you are looking for a replacement door, simply measure the width and the height of the current door.

Standard Bedroom Door Size

  • If you are adding a new one or replacing the door jamb, a good rule of thumb is to add 2 1/2 inches to the width of the door and add 3 1/2 inches to the height of the door. The additional inches will allow you to make adjustments in order to insert the door in the opening. However, this guideline may not be applicable or may change especially of you have a tall threshold or have wooden floors.
  • The door thickness for interior doors is usually 1 3/8 inches thick.

Standard Bedroom Door Size

  • Jamb thickness is the thickness of the wall where the door jamb will be fitting into, which includes the drywall, 2×4 studs and the 2nd drywall or any siding. This is not the width of a door or the width of the opening. For example in the picture below, the drywall has a thickness of 1/2 inches, the 2×4 studs have a thickness of 3 1/2 inches and the siding has a thickness of 1/2 inches. Therefore the jamb thickness is the total thickness of drywall, 2×4 studs and siding which is 4 1/2 inches. Then add an additional 1/8 inch allowance to make sure it covers completely which gives an overall total of a 4 5/8 inches jamb.
