Leather Weight and Thickness

Leather is usually measured in terms of ounces. One ounce equals 0.4 millimeters, thus a weight of 3 to 4 oz. means the leather is 1.2mm to 1.6mm thick. In an effort to make leather a uniform thickness, hides are run through a splitting machine. However, each animal is different and there is always a slight thickness variation throughout the hide. This is why leathers are usually shown with a range of thickness, such as, 2 to 3 oz., 1.4 to 1.6mm., etc. If a single measurement is given, such as 3oz, it is assumed to be the average thickness of the hide.
