How to find the right VELUX roller blind size — no measuring required

Super easy and no tape measure needed. To find the type and size of your VELUX window for which you want to select a roller blind, just read the code from the data plate on the window sash.

Fit guarantee

Fit guarantee means we match the roller blind according to the window’s data plate. If, despite providing correct data, the product doesn’t fit, we will provide a free replacement for the correct version.

Where to find the data plate

Open your VELUX roof window. In the upper left or right corner of the window sash (the moving part of the window), you will see a data plate with a code.
The letters indicate the window type, and the code (e.g., MK04) indicates its size. Example from the illustration below: window type: GGL, window size: MK04.

Select this data in the configurator on the product page. The type and size together guarantee a perfect fit.
