Measure Your Door

When you are ready to order your new door it is vital that you know the correct dimensions to ensure you order the right size so that it fits perfectly.

We have listed a few helpful hints to assist you in being able to obtain the correct dimensions.

Most doors are supplied measured in inches but some are in centimetres, please see our size conversion chart if you need to convert an existing measurement.

If you already have a door in place then simply take the measurements from that door, assuming that door is a perfect fit:

  1. Take a width measurement across the top, the middle, and the bottom of the door to establish that the width of the door is the same all the way down.
  2. Then take a height measurement from each side of the door from top to bottom to establish the height of the door.
  3. Then you will need to measure the thickness of the door.
  4. You know have a width, height, and thickness measurement, these are all the measurements needed to place your order.

If you are fitting a door where there is no door currently in place or you have a badly fitted door then here are a few hints to help you to measure for the correct size of door to fill the gap. 

  1. Take a width measurement across the top, the middle, and the bottom of the door frame to establish that the width of the door is the same all the way down. Then take 3mm away from this measurement to allow for a gap.
  2. Then take a height measurement from each side of the door frame from top to bottom to establish the required height of the door. Then take 3mm away from this measurement to allow for a gap.
  3. You will need to decide on which thickness of door to order, normal doors are usually 35mm and fire doors are usually 45mm.
  4. You know have a width, height and thickness measurement, these are all the measurements needed to place your order.
