Leather Weight/Thickness Chart

Posted by NekDel L on

The thickness of leather is measured in ounces, and each ounce equals 1/64 of an inch. So, a 4 ounce piece of leather would measure approximately 4/64”, or 1/16” thick. To accommodate variations in thickness across a split hide, leather weights are often given in ranges. For example, 6oz-7oz.

A lighter weight leather will be more flexible, while a heavier weight leather will be more durable.  Below is a table to help you with the conversion:

Leather Weight (Oz) Thickness (mm)
1 0.4
2 0.8
3 1.2
4 1.6
5 2
6 2.4
7 2.8
8 3.2
9 3.6
10 4
