Window Blind Measuring Guides

Please use your exact measurements

The more precise you are, the more precise we are. We cannot accept responsibility for measurement errors when ordering.

We have text and/or video guides for different types of measurements (recess, actual or fabric width). Please use a steel tape measure or a laser/digital measuring device (electronic tape measure) when measuring as the cloth tape measures can stretch or bend and give false readings.

Please note for recess sizes we would make deductions to blind sizes given to ensure the blind fits within the recess, this will be explained in more detail below.
