Guide for measuring your new PVC windows

How to measure for new PVC windows

Windows are usually measured from the brickwork opening from the outside of the property, always in millimetres (mm). Viewd from the outside.

Firstly, measure the width, brickwork to brickwork or plaster to plaster, in three places (top, middle and bottom) and deduct approximately 10mm from your smallest measurement.

Secondly, measure the height of the opening in a few different positions and again deduct approximately 10mm from the smallest measurement.

Please note: If your property is rendered (plastered) then it’s a good idea to remove some of the render in order to view the brickwork edge. Depending on the thickness of your render you may require frame extenders.

Some important points to remember

Measure from outside, brickwork to brickwork. (plaster to plaster)

If that is not possible, measure your existing window.

Measure in a few different positions, take your smallest size and deduct approximately 10mm.

If in doubt, just ask!
