What does it mean?
A leather’s weight refers to the thickness of the leather. The most common units for leather weight are ounces, millimeters, and inches. Again, each of these measures the thickness of leather. If you need to convert leather weight between these units, you may find our conversion chart useful. Note that all weights on a row are equal, for example, 1 ounce is equal to .4 millimeters which is equal to 1/64 inch. You’ll notice that 1 ounce is 1/64 In, this ratio is true of all sizes and is a good rule of thumb to keep in mind when considering leather weights.
The Weight of a leather determines the strength and flexibility characteristics of the piece. With heavier (thicker) leathers tending to be stronger and less flexible while light leathers are more pliable but not quite as tough. Heavy leathers (above 7 ounces) are good for products like holsters, saddles, and belts. Light leathers (below 6 ounces) are great for wallets, small bags and apparel.
It’s important to note that there is a great deal of flexibility when it comes to leather applications. Many leathers can be used for most projects, so choosing the right one will often be a personal preference and specific to your project needs.
