7 mm scale, also known as British O scale is a model railway scale of 1:43.5 (or 7 mm to 1 ft; hence its name).[1] The scale is thus different from American O scale (1:48)[1] and European O scale (1:45). For standard gauge railways, 32mm gauge, or 0 gauge is most commonly used.[1] ScaleSeven (S7) standard however specifies 33 mm gauge, which is closer to scale.[1] For narrow gauge modelling, 16.5 mm gauge
