"Quarter-size" refers to an object or measurement that is approximately the same size as a U.S. quarter coin, which has a diameter of about 0.955 inches (24.26 mm). This term is often used in various contexts, such as describing the size of a small item, a wound, or a growth. In practical applications, "quarter-size" can help people visualize dimensions when comparing items. For example, a quarter-sized piece of fruit might be a small apple or a cookie, making it easier to understand the expected size without needing precise measurements.
