When replacing an existing door or installing a new door, you’ll need to know how to measure for new doors. So, get out your measuring tape, a pencil, and print off our simple worksheet so you can gather the following three measurements you will need for each door:
- Rough Opening Width: Measure the width of rough opening at the top, center and bottom for each door and record the smallest measurement.
- Rough Opening Height: Measure from the floor to the bottom of the header and record the measurement for each door.
- Wall Width – measure the width of the wall for each rough opening space. The width should include the sheeting on each side of the stud. Most interior walls are 4 9/16” wide. Exterior walls can vary.
Record the measurements you take on our simple worksheet so you’ll have the information handy when you are ready to order your new doors.
Here’s a good video showing where to get these measurements from an existing door:
