Velux Measurement

Finding your window code

Measuring for roof blinds couldn't be easier - you just need to find the code on your window. Look for a plate on your window frame.

For Velux® windows you are looking for a code which is made up of two parts.

For Keylite, Rooflite, Fakro and Dakstra windows you just need to find a single code.

See the measuring guide on the product page for further information.
