How to Measure for Blinds, and Why a Survey Beats a Tape Measure

Blinds only look right when they fit well, and that starts with accurate measuring. If you would like to understand how it works, or take a first set of measurements yourself, here is a simple guide.

Decide where the blind will sit

Inside the recess

A blind fitted inside the window recess gives a clean, tailored look. It needs a recess that is deep enough, and the window frame and handles must not get in the way.

Outside the recess

A blind fitted on the wall or frame, overlapping the opening, hides the window edges and is better at blocking light. It also makes a window look larger.

How to measure

Use a steel tape measure and record sizes in millimetres. Measure the width at the top, middle and bottom of the window, and use the smallest figure for a recess fit. Do the same for the height. For a recess fit, also check the depth, and look for anything that could get in the way, such as handles, window ledges, radiators or pipes.

For an outside fit, measure the area you want to cover and add enough overlap on each side. A little extra width helps block light.

Why a survey is better

Windows are rarely perfectly square, and small errors can cause gaps, rubbing or a blind that will not sit level. When we survey, we measure every window ourselves, check how and where it can be fixed, and talk through mounting options, fabrics and controls with you. It is free, and it takes away the risk of ordering the wrong size.
