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.
