Measuring for your Door with Sidelight

Frame Style specialises in bespoke uPVC doors and we can accommodate for all openings. This can sometimes mean having a sidelight when the opening is too large. To take measurements for this is as easy as measuring for a door only especially when we are on hand to give you step-by-step instructions.

What you will need:

  1. Pen
  2. Paper
  3. Tape Measure

Important Information: we need the EXACT measurements of the overall frame before we can manufacture your bespoke uPVC door.



Write down measurements for points A, B and C.
Using the smallest of the three positions deduct 10mm to allow for fitting tolerance and sealing.


Take note of the measurement points A, B and C – always start with A.
Use the smallest measurement of the three and deduct 10mm, this allows a fitting and sealing tolerance.

When you come to order your product you will need your measurements as:

Height: xxx
Width: xxx
Preferred sidelight weight:

NB. We will always try to make your sidelight to the preferred measurements as long as this allows the door to be within the min/max width.

If you come across any issues or you are not 100% sure what you need to do, feel free to give us a call on 0800 211 8933, our agents are waiting.
