An Overview of Leather Thicknesses

One ounce of leather is equal to 1/64" in thickness, but hides rarely measure to the exact 1/64" throughout, as there are always slight variations in thickness. Hides run through a splitting machine are more consistent, but still not perfect. It is best to remember that the more ounces there are, the heavier the leather will be. The chart below provides basic leather conversions and the uses of each size.


* Always remember that leather is a natural material that’s not intended for use on products that carry a high liability or certification of tensile strength. On occasion, leather fibers can become weak without any visible signs of wear. Fall arrest or safety equipment should never be made with leather constructing the strength member. More consistent materials like heavy-duty webbing should be used for strength member construction.
