For a perfect fit, you need to discover the reference on the window type sign at the top of the window. You will need to record this information for the order process.

Find the right size blind for your roof window

The below illustration shows a VELUX window type sign. Type signs differ in appearance depending on the model of your window. Most roof window manufaturers include a type sign like this on their windows that shows the window type and size. To order a blind you will need to specify: Window type and window size. E.g. GGL M08 as below.

Can't find the code for your VELUX roof window?

If for some reason the type sign is missing on your VELUX roof window, you can use this size chart to find the size code for your window.

If in doubt as to what your roof window reference code is, please do contact our customer service at for advice.

Find the right size for your Keylite roof window

Itzala value blinds also fit Keylite roof windows. However it is not so straightforward to find the correct size blind for a Keylite window because they do not list the size on the type sign like the other manufacturers. If you want to buy a blind for your Keylite window you therefore need to measure the internal glass size to find out which blind to buy. Just measure the width and height (in millimetres), and then choose the brand Dakea and use the corresponding code to get a perfect fit.
