FAKRO roof window blinds are designed and manufactured to fit FAKRO windows. The information on your ID plate (shown below) contains all the information you need to order the correct blind size for your window. In the example below the size of 78/98 means this window requires a 78cm x 98cm blind.
It is not necessary to measure any part of the window before ordering a blind, this measurement is all that's required.
If your window is a custom size (meaning a custom size blind is required) the measurement will also be on the ID plate. You can discuss this measurement with the our team over the phone, who will be able to provide you with a cost and place the item online for ordering.
