If you check the size guide on a product page you will see that there are different measurements for every one of them. We want to give our customers the best possibilities to choose the right size which is why the measurements are provided in a table. The centimeter and inches equivalent measurements are both provided to make it easier to visualize the size in their preferred unit of measurement.
We highly recommend comparing the measurements from the size guide with your own measurements before ordering.
If you have other concerns about our size guides, feel free to reach out to us.
