1.
actual size; real dimensions; true measurements
The real, measured dimensions of an object as opposed to scaled or approximate sizes. Commonly used in shopping, manufacturing, and design contexts.
A compound of 実 (actual, real) and 寸 (measurement, dimension — from the traditional unit of length). Despite the origin of 寸, the word refers to actual measurements in any unit, not just the traditional Japanese inch.
