Thickness or Weight  

Leather is usually measured in terms of ounces. One ounce equals 1/64th of an inch thickness. Thus, a weight of 7 to 8 oz. means the leather is 7/64th to 8/64th of an inch thickness. In an effort to make leather a uniform thickness,wet 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,4 to 5 oz.,6 to 7 oz.,etc.


Some simple examples of thickness based on US coins:

A dime = 3 oz
A penny = 3.5 oz
A quarter = 4 oz
A nickel = 4.25 oz
