Watch our step-by-step video guides covering everything from measuring to installation.
How to Measure Your Windows
Measure windows from the outside using the brickwork opening, in millimetres (mm). Measure the width in three places (top, middle, bottom) and the height in a few places, then use the smallest measurements and deduct about 10mm. Exclude any metal lintel from the height, and if the window sits on a cill, measure from underneath it unless the cill is fixed (such as stone).
