If you're thinking of replacing the old door with a new one, it’s highly important to understand the size. There are many homeowners who get confused between the terms “the average door height” and “standard doorway dimensions” while purchasing a new door or replacing the old one. This blog explains the average height of the door frames and also about door measurements to help you get the best-fit door for your home.
What Should Be the Height of the Door Frame?
The average height of most domestic frames measures 6 feet 8 inches, or 80 inches tall. This measurement has been a benchmark for decades, allowing sufficient headroom for most adults.
Modern homes like custom and luxury buildings make tall ceilings and therefore use taller door frames that measure about 8 feet (96inches) , 9 feet(108 inches ), or 10 feet (120 inches).
Why Proper Measurement is Necessary?
If you're looking to replace or renovate your door frame, knowing the measurements of door frames can help, especially if you need to match existing openings. Even a little mistake in frame height can cause gaping, sticking, or alignment issues. Therefore, homeowners consider professional measurements.
Standard Measurement of Interior Doors
The average measurement of interior doors in the U.S. is usually 80 inches tall and 28-30 inches wide. Depending on the use, the average size may vary. For example, the height of closet doors or bathroom doors may differ to complement the existing interior design. Some standard interior door sizes include:
| Door Types | Height | Width |
| Closet Doors | 80 inches | 24-36 inches |
| Bathroom Doors | 80 inches | 28-32 inches |
| Bedroom or Office Doors | 80 inches | 28-36 inches |
| French Doors | 80 inches | 48-72 inches |
It should be noted that these measurements are just the general rules, but different manufacturers might give different measurements. Therefore, the smart way is to measure the actual opening of your home before buying a new door.
Standard Measurement of Exterior Doors
The average measurement of exterior doors in the U.S. is usually 80 inches tall and 36 inches wide. Depending on the intended use and the type of building, the average size may vary. Some standard exterior door sizes include:
| Door Types | Height | Width |
| Front Doors | 80 inches | 36-42 inches |
| Patio Doors | 80 inches | 60-72 inches |
| Double Doors | 80 inches | 60-72 inches |
| Garage Entry Doors | 80 inches | 32-36 inches |
Just like the exterior doors, it should be noted that these are some standard measurement rules, but different measurements might be given by different manufacturers. Additionally, it's always good to measure the actual opening of your home before buying a new door.
Things to Consider Before Choosing the Right Door Size
Choosing a random dimension of door frames might not work out; consider certain things before choosing the right door height.
Measure the Doorway Accurately
Avoid the incorrect measurement. Measure the height and other dimensions of the door accurately to ensure a perfect fit. For proper alignment of the door frame, consider the door frame, rough opening, and installation fin space.
Size of the Room
The size of the room plays an important role in deciding the dimensions of the door. For instance, large rooms or living areas usually need tall and wider doors to allow easy movement of furniture and also let more light enter indoors.
Building Codes
Many states in the U.S.A. follow some kind of the IRC, which sets rules for the minimum and maximum height and width of doors and how the door swings.
Insulation
If you live in a place with heavy noise or you have some drafty spots in your home, tall and solid doors will work efficiently in blocking the noise.
Every single inch matters while installing a door. The right door size is more about the functionality than the look.
Consider These Steps to Measure Your Door Properly
If you're thinking of replacing the existing door with a brand new door of the same dimensions, make sure to follow these steps.
- Start by measuring the door from top to bottom and left to right.
- Do not forget to measure the thickness of the door.
- Make sure that you do not go beyond the average measurement of thickness, which is about 1 ¾ inches.
- Ensure measuring the breadth of the door jamb and the height and width of the frame.
- Do not include the trim in your measurement.
- Finally, add 2 inches to the width measurement of the door and 2 inches to the height of the door. This is a rough-in measurement.
Conclusion
Getting a new door frame can be a little challenging because the frame measurements should balance between functionality and the look of your home. There are standard measurements of the door height that may guide you to purchase the right door size. However, the smartest way is to consider the basic rules and steps to get a door that fits best in your home.
