Doors Are Designed to Fit a Specific Frame Size

You probably know that the Standard exterior door size is 36 inches wide and 80 inches high. You may be less familiar with the Standard interior door size, which is 32 inches wide and 1 3/8 inches thick. But, did you know that doors are also designed to fit a specific frame size? In other words, a door is designed to fit the opening of your house, not the other way around. Nevertheless, knowing the exact size of your frame will help you determine the right door size for your home.

Standard exterior door size is 36 inches wide by 80 inches tall

WDMA standard exterior door size is 36 inches wide by eighty-one centimeters high. These dimensions are generally adhered to by most building districts and are the same for all homes. However, there are exceptions. Some doors are as wide as thirty or 32 inches and as tall as 96 inches. A steel or fiberglass door is also available in this size. To ensure a good fit, you must measure the width and height of the doors.

Standard interior door size is 32 inches wide by 1 3/8 inch thick

The standard interior door size is 32 inches wide by 1-3/8 inch thick, with the width and height of each dimension equal to or slightly larger than the room size. If you need to add a door to a larger room, make sure to make the rough opening two inches wider. The door should also be a minimum of one-third of the room's height and width. Purchasing a door that doesn't fit the room's size can result in a poorly fitting door.

Standard door frame size is wider than the door opening

Standard door sizes are not the same as the door openings. The frame size is often wider than the door, with the width of the post varying from two to four inches. The width of a door also varies, with standard internal and exterior door widths being around 32 inches and 36 inches, respectively. These sizes are generally wide enough for most people to pass through without bumping into their heads. However, you can also order doors with narrow widths of 28 inches and 24 inches.

Doors are designed as per the required size

Interior doors can be narrow or wide, depending on the needs of a room. The width of a closet door may not be as wide as a standard interior door, but it still needs to be at least 36 inches wide to fit into the space. A minimum door frame width of 32 inches is required by the Fair Housing Act in order to accommodate a wide variety of people, including people with mobility issues. Doors are typically sized to meet this standard.

Doors are made from different materials

Interior doors are generally thinner than exterior doors. A standard interior door is 1 3/8 inch thick. Many types of interior doors are made of wood. Pine is the most popular type, while poplar and alder are next. Hardwood species are available for high-end stain-grade work, but they are more expensive. There are several different types of interior doors, and standard sizes vary accordingly. Here are some tips to help you decide which one is best for your home.

They come in different sizes

While interior doors are usually the standard size of 32 inches, doors in bathrooms, closets and pantries are not. Instead, they may be 28 or 30 inches wide. Pocket, French and sliding glass patio doors may all be slightly different in size, too. Custom doors are available in any size or width, too. Home improvement retailers typically stock several different prehung door slabs in different sizes. While some stores are willing to make substitutions, others may not.

They have different thicknesses

When shopping for an interior door, it's important to know the thickness of the door itself. Standard doors are 1 3/8 inches thick, but you can find some that are a little thicker than this. Exterior doors are typically one and a half inches thick. And, of course, if you're installing new hardware on the door, you'll need to take into account the thickness, too. Then, you'll have to decide if you want a door with extra-thick panels or a thin, low-ply wood finish.
