How to Measure a Door
Wondering how to measure door size to ensure you select a front door that fits your door frame? We’ve got you covered with this five-step DIY door measurement guide.
Learning how to measure a door opening is essential when ordering your new Stegbar door. Taking accurate measurements will help you select the right front door from a range of front door sizes to ensure a perfect fit. Getting that right is crucial for both aesthetics and functionality.
Here’s a step-by-step door measurement guide to help you measure for your new door.
What you need
- Measuring tape
- Pencil and paper
- Level
- Step ladder (if necessary)
Step 1: Measure the Width of the Door Opening
Measure Three Points:
Use your measuring tape to measure the width of the door opening at three points: the top, middle and bottom. This helps account for any irregularities in the frame.
Record the Smallest Measurement:
Write down the smallest of these three measurements. This will be the width of your new door.
Step 2: Measure the Height of the Door Opening
Measure Left and Right Sides:
Measure the height of the door opening from the floor to the top of the frame on both the left and right sides.
Record the Shortest Measurement:
Write down the shortest measurement. This will be the height of your new door.
Step 3: Measure the Thickness of the Door Jamb
Measure the Door Jamb:
Measure the thickness of the door jamb (this is the frame into which the door fits). This is typically 35mm to 45mm, but it’s important to confirm.
Step 4: Check for Squareness
Take Diagonal Measurements:
Measure the diagonals of the door opening from the top left corner to the bottom right corner, and from the top right corner to the bottom left corner.
Compare Measurements:
If the measurements are equal, the opening is square. If not, you may need to make adjustments during installation.
Step 5: Account for Flooring
Consider Flooring Height:
If you plan to install new flooring, account for its height in your measurements. This ensures the door will clear the floor when open.
