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 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.
