A 35mm buckle size typically refers to the width of the buckle frame or the opening of the buckle where the belt is inserted. This measurement is also sometimes referred to as the “buckle tongue width.” A 35mm buckle size is equivalent to 1.38 inches, or just over an inch and a third.
A 35mm buckle size is a common size for belts worn with jeans or casual pants. It is also a popular size for men’s dress belts. When selecting a belt with a 35mm buckle, it is important to ensure that the belt width matches the buckle size for a proper fit.
