VELUX® Skylight Window Codes

A common question that we are asked is “How do I find my VELUX® Skylight Window Code?”. 

Finding the right VELUX® Skylight window code is really simple and in most cases no measuring is required. Window manufacturers attach a product plate to the frame giving you the window code.

Use the illustration below to give you an idea of what information should be on the plate. If you can’t find one, then simply measure the visible glass size, and use the table below to find the code, or give us a call, and we will ascertain the correct code.

IF YOU NEED ANY ASSISTANCE IN FINDING YOUR WINDOW CODE THEN PLEASE GIVE US A CALL ON 0800 008 6293 OR EMAIL US AT team@skylight-blinds-direct.co.uk AND WE WILL BE HAPPY TO HELP

Once you have confirmed your window code go straight to the VELUX® Skylight Blinds category here

Skylight Window Product Plate

The product plate will look something like the image below. Note down the code as illustrated below. A letter/number/letter sequence. 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.
