Roller Blind Measurement Guide

Our simple to follow guide to measuring your window for blinds will have you ordered in under 10 minutes.

Here at Roller Blinds Direct, we think measuring for your new blind should be as easy as 1,2,3. This is why we have created a simple guide for you to follow.

To help you with your measurements you will need a metal tape measure.

All your measurements need to be in centimetres and also to the nearest 0.1cm.

Our fabric experts recommend when ordering a blackout blind, that you fit this outside the window recess using the exact blind measurements. This ensures it blocks out as much external light as possible. Just follow the measuring guide below, and we will take it from there!

Recess Measurement

Select this option when you would like your blind to fit within the window recess.

Recess Width

Take 3 measurements for the width of the window recess as shown in the picture.

Take the smallest of these measurements. This is your recess width.

We will make the necessary deductions for the mechanisms, brackets and clearance to ensure the blind operates within the window recess.

Note: The actual fabric will be approximately 3-4cm narrower than the recess width depending on the blind ordered. See cloth measurement diagram below.

Recess Drop

Take 3 measurements for the drop of the window recess as shown in the picture.

Take the smallest of these measurements. This is your recess drop.

Exact Blind Measurement

Select this option when you would like your blind to fit outside the window recess.

Exact Blind Width (also known as pin width or finished blind width)

Decide how much you wish to overlap the recess at each side. We recommend at least 7.5cm each side to minimise as much external light as possible.

Take the overall width measurement including the overlap. This is the Exact Blind Width.

Note: This width includes the mechanism of the blind and is not the width of the cloth. See cloth measurement diagram below.

Exact Blind Drop

Decide how much you wish to overlap the recess at the top & bottom. We recommend at least 7.5cm at the top, if the blind is required to roll up fully above the window recess.

Take the overall drop measurement including the overlap. This is your Exact Blind Drop.
