Measuring Guide for Doors Fitted Into Existing Frames
Steps to Follow

The door measuring guide provides essential information to ensure accurate measurements for your new door.
What To Do?
- Measure the height of the opening on both sides (H1 and H2).
- Measure the width at the top and bottom of the opening.
- Measure the thickness of the existing door.
Example
Measurement | How to Measure |
---|---|
Height | Measure both sides (H1, H2) |
Width | Measure top and bottom |
Thickness | Measure the door thickness |
Use the largest measurements to determine the size you need. Standard door sizes in the UK are usually listed as height x width x thickness.
Quick Recap
- Measure width at the top and bottom of the opening.
- Measure height on the left and right sides of the opening.
- Measure the inside edge of the frame for accurate dimensions.
Measuring Guide for Doors Without Existing Frames
Steps to Follow
If you don't have a door or frame in place, you can still measure for a new door. Here's how:
- Measure the height of the brickwork opening in three places: left, centre, and right.
- Measure the width of the brickwork opening in three places: top, middle, and bottom.
Allowing Clearance
When ordering a new door frame, allow a 10mm fitting clearance. This ensures the frame fits into the opening without any issues. Deduct this clearance from your measurements to find the correct size for your door and frame.
Example
Measurement | Where to Measure |
---|---|
Height | Left, centre, right |
Width | Top, middle, bottom |

When selecting a new door, consider these popular styles to enhance your home's aesthetic:
