The word 规模 is formed by combining two characters, each contributing a distinct metaphorical image related to measurement and form. The first character, 规 (guī), originally depicted a compass used for drawing circles, thus representing a standard, rule, or prescribed limit. The second, 模 (mó), originally referred to a mold or pattern used for casting objects, conveying the idea of a model, blueprint, or tangible form. When fused, the compound creates a conceptual blend where 规 establishes the prescribed scope or standard, and 模 provides the structural model or blueprint that gives it shape, together yielding the abstract meaning of "scale", "extent", or "scope", the defined dimensions and proportions of something.
