"Quarter-size" refers to an object or measurement that is approximately the same diameter as a U.S. quarter coin, which is about 0.955 inches (2.42 cm) across. This term is often used to describe the size of small items, such as coins, buttons, or even certain fruits like cherries. In various contexts, "quarter-size" can help people visualize dimensions quickly. For example, when discussing the size of a wound or a blemish on the skin, saying it is "quarter-size" gives a clear idea of its scale, making it easier for others to understand the extent of the issue.
