Not sure how to pick the right blind for your Roto roof window? Super easy!

Picking the right size for your Roto roof window blind can be stressful. That’s why we built a foolproof process that eliminates all risk.

What to look for?

Every Roto roof window (even 40-year-old!) has its own unique code with size and model info.

Don’t measure the window! Roto gives the size as a code (like 7/9, 11/11), not centimeters.

The code is usually located (depending on window age and model) under a red, blue or grey plastic flap. Sometimes on exposed metal plates. Check below:

IMPORTANT: Nothing’s printed on the plastic flap itself. You gotta lift it to see the real code.

Roto roof window nameplate with size code under flap — You’ll find the code under a **red**, **grey** or **blue** plastic flap. Sometimes on the **metal plate** itself.

Where to look?

Nameplates can be in 4 spots on your Roto roof window. Check the drawings below to find yours:

Four possible nameplate locations on Roto roof window — Example above: **window size:** 9/11, full **Roto window code:** WDF R85 KBW 9/11.

EXPERT TIP:

Never copy the code from the aluminium frame inside the glass! That’s the glass code, not the window. We need the code from the window sash/frame.
