Frequently Asked Questions
What does leather oz mean?
Leather weight in ounces refers to thickness: 1 oz = 1/64 inch (≈0.4mm). It originated from the weight per square foot but now primarily indicates thickness.
What thickness is best for wallets?
Wallets work best with 2–3 oz leather (0.8–1.2mm). Too thick makes them bulky; too thin lacks durability.
What thickness for belts?
Belts typically use 8–10 oz (3.2–4.0mm) leather for durability, sometimes doubled (two layers) for extra strength.
