Internal doors are usually made to fit several standard sizes. If you are simply replacing the doors in your home, then you can use the measurements of your existing doors to work out the sizes you require
This is a lot easier than working out the doors you’ll need by only measuring the frame.
XL Joinery doors are available in a range of different sizes including both standard imperial and metric sizes. By following these steps, you will be able to accurately measure your door.
Start by laying a large protective sheet or covering on the floor. Carefully unscrew the hinges from the frame and lay the door flat on the sheet.
Take out your measuring tape and simply measure and mark down the doors:
- Length in 2 places; left and right side
- Width in 3 places; top, bottom and middle
- Thickness in 2 places; top and bottom

It is important to measure in a number of places to gives you an accurate depiction of the door as the frame and door could have warped since it was first put up and many people who haven’t measured a door themselves forget this part.
Once you have chosen your preferred door design, use your measurements and match them up with the listed available product sizes; most doors will have to be shaved to fit your door frame seamlessly.
