Standard Door Sizes: A Comprehensive Guide

There are several reasons why you might choose to buy a new door. You can use it as part of a home remodeling project, or you can use it to replace a broken door in your home.

Whatever the reason, it's important to note that there are different door sizes, dimensions, building codes, and other factors that will determine your choice.

When it's time to replace your door, you can choose from a pre-hung door or a door panel. Pre-hung doors basically include doors, frames, and hinges. Door panels, on the other hand, are simply door panels without hinges, frames, or any other hardware.

This is the first choice for most people looking to upgrade the door panels individually without breaking other components. If you're looking to buy a door, it's important to remember that for standard door sizes, the only measurement is the door panel.

You don't need to measure door frames, openings, or jambs all the time. Although there are many door sizes available in the market today, there is still one well-known standard size.

Below is a breakdown of standard sizes for interior and exterior doors:

Interior door dimensions for most buildings are determined by the International Residential Code (IRC). According to the specifications of these codes, interior doors do not need to be the same height or width as exterior or main entry doors.

However, the preferred standard size for interior doors should be at least 80 inches. Also, it's important to note that some interior doors that are not frequently used as access to the house (such as utility doors and closet doors) can be shorter, depending on the homeowner's preference.

You will find that utility and closet doors are approximately 78 inches tall in most cases. The width of interior doors varies from building to building. The width can be between 24 and 36 inches.

Most interior doors such as barn doors, folding doors, bathroom doors, and bedroom doors measure between 28 and 32 inches. However, these widths can be made taller or lower depending on the homeowner's preference.

The most common width for interior doors is 32 inches. This means that the standard size for most interior doors is 32" x 80".

The exterior doors of most buildings also depend on IRC. According to these codes, exterior doors are recommended to be at least 80 inches, although they can be taller or shorter.

The standard size for most residential building exterior doors is usually 36 inches wide and 80 inches high. Some homes today feature taller exterior doors, about 96 inches in height, based on new architectural designs. You can also find stock doors approximately 30 to 32 inches wide.

When it comes to sliding doors, you'll find that width and height vary from building to building. However, the common standard size for most sliding doors is 80 inches high and 72 inches wide. And, you can always find other sliding door sizes to fit your home, from 60 to 96 inches.

Before proceeding with door replacement, you must measure the height, width, and thickness of your current door. These measurements are the only ones you'll need, especially if you're replacing your current door with a door panel.

The size of the door panel is the only thing that matters, not the frame or even the opening. So measure your door from top to bottom and note the height, measure right to left and you will get the width, then measure the depth and get the thickness of the door you need.

Although size is one of the most important factors when buying a door, it is important to consider other factors as well. Factors such as cost, design, and privacy should also come into play when choosing the ideal door for your home or office. If you have any questions or want to buy a door, please contact us.
