How To Measure An Interior Door

How to Measure an Interior Door

Measuring an interior door correctly is essential for ensuring a proper fit when replacing or installing a new door. Here are the essential steps to measure an interior door accurately:

1. Determine the Door Width

Using a measuring tape, measure the width of the door opening from jamb to jamb, where the door will be installed. Measure the width at the top, middle, and bottom of the opening. Record the smallest of the three measurements as the door width.

2. Determine the Door Height

Measure the height of the door opening from the floor to the top of the jamb. Measure the height at the left, middle, and right side of the opening. Record the smallest of the three measurements as the door height.

3. Measure the Door Thickness

Determine the thickness of the door by measuring the thickness of the jamb where the door will be hung. This measurement will help ensure the door fits snugly into the frame.

4. Measure for Hardware

If you are also installing new hardware, such as hinges or a doorknob, measure the location where the hardware will be placed. This will help determine the correct placement of the hardware on the door.

5. Consider Jambs and Casing

When measuring for a replacement door, take into account the width and thickness of the door jambs and casing. These elements will impact the overall dimensions of the door opening and must be considered for a proper fit.
