Leather Thickness Chart

At Rustic Leather we want you to be informed about your leather purchase. Here is a handy & easy to use leather thickness chart.

Leather thickness is usually measured in ounces. One ounce equals 1/64" in thickness. Thus, a weight of 4 to 5 oz. means the leather is 1/16" to 5/64" in thickness. The thickness of leather varies to some extent throughout the hide. This is why leather is 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 7 to 8 oz leather.
