Selecting the best window seal size for your window is super easy.
Simply follow these steps:
1️⃣ For single casement windows (pic A): Measure the 4 sides of your window.
For double casement windows (pic B): Measure the 4 sides of one single panel - this part is where the product will be actually installed.
2️⃣ Then, choose the size which is closest to your perimeter:
| Size of your window/panel | Window seal to buy |
| Up to 320cm/126'' | 300CM |
| Between 320cm/126'' and 420cm/165'' | 400CM |
| Between 420cm/165'' and 520cm/204'' | 500CM |
| Between 520cm/204'' and 580/228'' | 560CM |
If you are in doubt between 2 sizes, select the bigger one.
👉A small note about some outwards opening windows and tilt windows
If you have a window that opens like the ones in the pictures below or you notice that there's a gap left next to the hinge side once the panel is open, make sure to select a window seal size that is bigger OR as big as your window so that your window seal can cover all the 4 sides of your window completely to avoid any air flowing back to your room.
