Feb 20, 2023

Interior doors and exterior aluminum doors and frames are essential parts of any home, providing security, privacy, and insulation from the elements. When it comes to redecoration, the doors are the inevitable topic. However, the selection of interior doors and exterior aluminum doors and frames is not easy, which relates to the size of the door and door frame. In this post, the author would solve all the frequently asked questions about the size of the interior doors and exterior aluminum doors and frames.

What is A Standard Exterior Door Size?

Frankly, the exterior door sizes are determined by the International Residential Code (IRC). According to this code, the exterior doors in the US should be a minimum height of 80 inches. The standard size for an exterior door in the United States is 36 inches wide by 80 inches tall (3'0" x 6'8"). However, exterior doors can also come in different sizes, such as 32 inches by 80 inches, 34 inches by 80 inches, and 42 inches by 80 inches. In some new properties, the exterior door is taller and higher. Then, aluminum sliding doors typically have an average height of 80 inches and an average width of 6 feet.
 

What is A Standard Interior Door Size?

As well as the exterior door, the interior door sizes are determined by the IRC building codes in the US. However, the interior doors are not required to be as large as the house front doors. In the United States, a standard interior door size is required to be 80 inches in height and 28 to 32 inches in width. Then, the minimum recommended door width for people who have movement difficulties is 36 inches.
 

How Thick is An Interior Door?

When you are choosing the thickness of the interior door, you could find that there are not as many thickness sizes as the width sizes or height sizes of the interior door. Two thickness sizes are available: 1⅜ and 1½ inches. Interior doors typically have a standard thickness of 1 ⅜ inches. However, if your interior door is wider than 36 inches or taller than 80 inches, building codes recommend using a thickness of 1 ¾ inches.

How Tall is A Standard Door Frame?

How Do You Measure Door Size?

●Step 1: Measure the Width of the Door
The first step in measuring a door is to determine its width. To do this, you will need to measure the distance between the two vertical edges of the door frame. Use a measuring tape to measure the distance from the left edge of the frame to the right edge. Make sure to measure at the widest point, which is usually at the center of the door. Write down this measurement, as it will be needed later.

●Step 2: Measure the Height of the Door
After measuring the width, the next step is to measure the height of the door. This is done by measuring the distance between the top and bottom edges of the door frame. Use a measuring tape to measure the distance from the top edge of the frame to the bottom edge. Again, measure at the highest point, which is usually at the center of the door. Write down this measurement, as it will be needed later.

●Step 3: Measure the Thickness of the Door
The final step is to measure the thickness of the door. This is done by measuring the distance from the front to the back edge of the door. Use a measuring tape to measure the distance from one side of the door to the other side. Write down this measurement, as it will be needed later.

Tips for Measuring Door Size:
●Use a steel measuring tape to ensure accurate measurements.
●Make sure to measure at the widest point of the door for both width and height.
●Measure the thickness of the door at the edge where the hinge is attached.
●Round up your measurements to the nearest 1/8th of an inch to ensure you have enough space for installation.
●If you're measuring an existing door, measure the actual door, not the frame.

In conclusion, measuring a door's size is a simple process that can be done with just a few measurements. By following the steps outlined in this article and taking note of the tips provided, you'll be able to accurately measure any door size. Keep in mind that having accurate measurements is essential when purchasing a new door, as it will ensure that it fits properly and operates smoothly.

What is A Standard Door Jamb Size/Door Frame Size?

When you are measuring and buying customized doors, the door frame is the crucial factor. It almost determines whether you can buy the right interior doors and exterior doors.
 

Most doors have an 84-inch wide gap between their door jambs. The thickness of a standard door jamb is contingent on the size of the frame and the drywall thickness. If the exterior aluminum door frames in your house are constructed with 2x4s, the typical thickness range is 4 9/16 inches to 5 ½ inches, with the larger thickness commonly found on doors that have thicker drywall. A 2x6 frame typically produces a door jamb thickness of 6 9/16 inches.
