Roller Blinds Measurement Guide

Measuring your windows to decide which size of roller blind to order is easy. Just follow these simple steps. Please use a metal tape measure to take measurements and use centimetres to the nearest 0.1cm.

Recess Measurement

Used when the roller blind is to be fitted inside 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 the recess width.
We will make the necessary deductions for the fittings & brackets to ensure the blind operates perfectly within the window recess.

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 the recess drop.

Exact Blind Measurement

Used when the roller blind is to be fitted 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 75mm or 3 inches each side to avoid gaps of light.
Take the overall width measurement including the overlap. This is the Exact Blind Width.
Note: This width includes the operating mechanism of the blind and is not the width of the cloth. See diagram C below.

Exact Blind Drop

Decide how much you wish to overlap the recess at the top & bottom. We recommend at least 75mm or 3 inches 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 the Exact Blind Drop.

Cloth Measurement

Used when the width of the cloth on the roller blind is important.

Cloth Width

Measure the width the blind cloth is required to be.
Note: The full width of the blind will be wider than the cloth width. See diagram C below.

Drop

Take the overall drop. This is the same as the Exact Blind Drop.
