F scale – using 1:20.3 ratio with 45 mm (1.772 in) gauge track. This scale uses the same gauge as, and is derived from the popular G scale. It is the largest popular scale/gauge combination, and is suitable for use in the garden. Perhaps not surprisingly, most narrow gauge modellers in the United States model US 3 ft gauge prototypes. However ...
Ridable, outdoor gauge, named according to the gauge in inches, and scale in inches per foot, for example 7 + 1 ⁄ 4 in (184 mm) gauge, 1.5 inch scale. The gauge is 7 + 1 ⁄ 2 in (190.5 mm) in the US and Canada, where the scale sometimes is 1.6 inch for diesel-type models. Private and public (club) tracks exist in many areas.

NEM gauges are arranged conveniently to use the normal gauge of smaller scales as narrow gauges for a certain scale. For instance, H0m gauge is the same as the TT-scale normal gauge, H0e same as the N-scale normal gauge and H0i same as the Z-scale normal gauge. For H0 and 0 scales, NEM uses the number zero, and NMRA uses letter "O" (HO instead ...
A variety of rulers A carpenter's rule Retractable flexible rule or tape measure A closeup of a steel ruler A ruler in combination with a letter scale. A ruler, sometimes called a rule, scale or a line gauge or metre/meter stick, is an instrument used to make length measurements, whereby a length is read from a series of markings called "rules" along an edge of the device.

Thus the scale and approximate prototype gauge are represented, with the model gauge used (9 mm for H0e gauge; 6.5 mm for H0f gauge) being implied. [ 2 ] The scales used include the general European modelling range of Z, N, TT, H0, 0 and also the large model engineering gauges of I to X, including 3 + 1 ⁄ 2 , 5, 7 + 1 ⁄ 4 and 10 + 1 ⁄ 4 ...
3 mm scale, also known as 3 mm finescale, is a model railway scale of 3 mm : 1 ft (305 mm) used for British prototypes. Introduced as British TT gauge , it sits approximately halfway between British N gauge and OO gauge but is not as popular as either and there is no longer any mass manufacturer ready-to-run support.
A scale ruler is a tool for measuring lengths and transferring measurements at a fixed ratio of length; two common examples are an architect's scale and engineer's scale.In scientific and engineering terminology, a device to measure linear distance and create proportional linear measurements is called a scale.
