How to measure for a new UPVC Front Door

These guidelines are to help you measure for a new UPVC front door and frame and make an accurate measurement.

Measure the door opening outside on both the height and width.

You have to always measure the exact brickwork opening and not the old frame or door.

Measure brick to brick in at least three different places and then deduct 10mm from both the final height and width measurements. - This is to allow for the for 5mm fitting allowance around the new frame. This will make sure the new frame will sit plumb and square once in place.

If you have any gaps then spacers and filler will be required to secure the frame into place and fill any of the gaps.


Vital: Please remember:

  • Do not measure your existing door or frame but measure the brick opening.
  • Make sure to measure in at least three different places and deduct 10mm from both the final height and width measurements - we do not make any fitting allowances on the sizes you provide.
  • All dimensions to be supplied in Metric and all designs viewed externally.
