VELUX® Window Sizes

How to find your VELUX window code

Firstly look for the data plate (see below),  then note down the code as illustrated below (it will most likely be a number letter sequence eg GGL M04). Then find the correct size on the drop-down menus on the Velux blinds page,  add to the basket, and then checkout.

If you can't find your code or your window doesn't have a data plate all is not lost. You can find the Velux window size by using the visible glass size. Use the table below to find your visible glass size and then follow the table to the left and it will tell you what code you have.  There is normally a prefix before the code eg GGL or GGU you can ignore those.  It is the window code that is the important part.
