FAQ

Why does the recommendation add around 2 inches?
That allowance typically places the buckle on the middle hole for balanced fit and adjustability.
What does the EU belt number represent?
It generally represents length in centimetres from the buckle end to the middle hole.
Can different brands vary?
Yes. Hole spacing and fit can differ by manufacturer, so use this as a baseline and confirm with brand charts.
