How to use the size template?

Just put the top right corner of your item into the blue space, then check which space the opposite corner (bottom left) fits in.

If it’s in the green space and the thickness does not exceed 5 mm, then the size is XS.

If it’s in the yellow space and the thickness does not exceed 20 mm, then the size is S, and so on.

EXCEPTION: No “square” item can be sent as XS, even if it’s very small. Because of its “unusual” dimensions, it will have to be stamped for the next category up, in this case: S
