How the Thickness of Leather is Measured!

Leather thickness is usually measured in ounces. One ounce equals 1/64" in thickness. Thus, a weight of 7 to 8 oz. means the leather is 7/64" to 8/64" in thickness or approximately 1/8" thick. The thickness of leather varies to some extent throughout the hide. This is why leathers are usually shown with a range of thickness such as 4 to 5 oz., or 6 to 7 oz. As a comparison, a quarter (coin) is equal to a 4 oz. thickness.A standard thickness for belts is a 7 to 8 oz leather.
