What is Door Frame Standard Size?

The standard size of a door frame depends on its size. It is slightly larger than the door itself to have minimal space in between for friction-free movement.

The height of the frame is generally 2 inches bigger than the door, while the width is only 0.5 inches bigger.

That said, if the door is 80 inches x 32 inches, the frame size will be 82 inches x 32.5 inches. It is the standard size of the door frame, but there can be minimal ups and downs.

Door Thickness

The interior door can be less thick. The standard thickness is 1.75 inches. However, the thickness of the exterior door ranges from 1.75 to 2.25 inches. Some doors also have custom thicknesses according to the needs and preferences.

How to Measure Doors and Door Opening Sizes?

Measuring doors is pretty simple.

1. Gather your tools – Get a measuring tape.
2. Measure the door itself – Place the tape at one end of the door and stretch it to the other end. Note the measurements for both the height and width.
3. Prepare to measure the door opening – Open the door completely so it is perpendicular to the frame.
4. Measure the opening width – Measure the clearance from the face of the door to the frame. Take measurements at the top, middle, and bottom of the opening.
5. Measure the opening height – Measure from the top frame down to the floor.
