Roller Blinds - How to Measure them

Roller Blinds - How to Measure

Introduction

There are a number of things you need to consider when measuring for new Roller Blinds. Below is a quick guide to help you. Firstly make sure you have a pencil and some paper and a tape measure (preferably a metal one).

What to measure in

Always measure in millimetres (mm) as most blind suppliers require a size in millimetres.

Where to measure

In normal window areas there are 2 potential places for your blinds to be installed, these are known as the window face, or the window recess. Roller Blinds can be fitted to the face of your window frame or wall, or into the top of the window recess. This gives you complete control over the positioning of your blind.

For a recess measurement:

Make sure you have enough depth to mount the inside the window frame area. 75mm should be fine; any less will result in the blind protruding out of the recess. If you have less than 75mm it may be worth considering installing your blind outside the window recess as a face fit.

1) Measure the width of the recess from wall to wall at the top. This is where the brackets will be fitted. Be sure to measure across 3 areas of the width to ensure the area is the same width (or very similar) and the walls do not have bulges that will affect the operation of the blind. 
2) Note down the shortest measurement. 
3) Take off 10mm each side - this will give you some flexibility in case of any variants in your walls and will ensure your blind doesn't get damaged. If you want total light block out we suggest you fit your blind to the window face. 
4) Measure the drop by taking the measurement from the top of the recess to the bottom. 
5) Note down the shortest measurement.

A stopper is provided with many Roller Blinds which means you can restrict the movement of the blind to ensure it extends down to fit perfectly on your windowsill. Operate the blind chain with one hand and with the other pinch one of the chain balls between your thumb and forefinger and work out when this will reach the top of the mechanism. When you have your perfect length worked out nip the blind chain stopper onto the chain with a pair of pliers.
