Roof Blind Measuring & Fitting 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 when measuring as the cloth tape measures can stretch or bend and give false readings.

Ensure you select the correct brand and the exact matching code when ordering.
Although some codes have the same blind size, some have slight differences such as a P04 is different to an 04, and a MK06 is different to a M06.
No plaque visible? Check the GLASS SIZE on our Velux chart, Keylite chart, Fakro chart, RoofLITE chart.
