What 40 mm means in practice

A wide strap is made for jeans and casual trousers with wide loops; before ordering, check that your loops are at least as wide as the strap, because dress-trouser loops are often narrower. Width is measured straight across the strap in the middle of its length, not at the buckle or the tip. This page lists 5 files from 2 brand(s); 2 of them are reversible. Buckle families: LV initials, LV wire-outline, Double G.

Comparing with neighbouring widths

A few millimetres change how heavy the buckle looks far more than how the belt feels. Compare with 38 mm before deciding, and check every width side by side in the width index; the belt width guide explains which outfits suit each band.
