Guides - Measuring VELUX Window Blinds

    Determine VELUX window codes including Size Chart

    To find out what size your VELUX window is, open your VELUX window and you will see a metal plate as shown below:

    In the box on the left side, as highlighted you will find your window code. You can enter this window code into our site to find the prices for blinds to fit your size window and order using that size.

    If you cannot find your window code or see a data plate, and are still sure it's a genuine VELUX window then you can refer to the chart below, which gives you the internal visible glass sizes.
