The thickness of a U.S. dime is approximately 1.35 millimeters or 0.053 inches. This small measurement makes the dime one of the thinner coins in circulation.
To put it into perspective, the dime is thinner than a quarter and slightly thicker than a penny. Its size and thickness make it unique among U.S. coins, which often leads to confusion when handling change. The dime’s thickness also plays a role in its design and functionality, ensuring that it can easily fit into coin slots and vending machines without issue.
