How to Measure Up For Roller Blinds

Getting the perfect fit for your made-to-measure roller blind is simple when you know how. Follow our easy measuring guide to ensure your new blind fits beautifully — whether it’s for a recess window or mounted outside the frame.

Decide on Your Fitting Type

Before you start measuring, choose whether your blind will be inside the window recess or outside (exact fit).

Recessed:

This is when the blind fits neatly inside the window frame. It’s a great option for a clean, built-in look.

Actual (Outside Recess):

This means the blind is fitted outside the window recess, usually over the wall or window frame. It’s ideal if you want to block out more light or hide an unattractive window frame.

Measuring for a Recess Fit

If you’re fitting your roller blind inside the window recess:

Measure the width of the recess in three places — top, middle, and bottom.

Record the smallest measurement.

Measure the drop (height) from the top of the recess to the window sill in three places and take the smallest measurement again.

We’ll make the necessary deductions to ensure your blind fits perfectly within the recess.

Measuring for an Exact Fit (Outside Recess)

If you’re fitting your roller blind outside the recess:

Measure the width of the area you’d like the blind to cover. We recommend adding at least 7.5 cm (3 inches) on each side of the window to help reduce light gaps if that is a priority.

Measure the drop from where you’d like the top of the blind to sit to where you want it to finish.

We’ll make your blind to these exact measurements.

Double-Check Your Measurements

Always use a metal tape measure for accuracy and record all measurements in centimetres. Check twice before placing your order — small differences can make a big impact on the final fit.
