2 mm scale, often 2 mm finescale is a specification used for railway modelling,
Since 2 mm scale is very close to the 1:148 British N scale, a hybrid specification can be modelled by re-wheeling proprietary British N-scale models to the 9.42 mm track gauge. This hybrid specification results in a track gauge equivalent to , slightly narrower than the prototype 4 feet inches. There is an advantage however in the narrower gauge as this allows more room for the outside motion of outside cylindered steam locomotives, which must be overscale in order to function correctly. This approach is often recommended for beginners. However, 2 mm-scale and hybrid-scale models do not usually sit well together due to the larger size of the latter.
Supplementary Standards
Like Protofour, 2 mm standards have been extended to several other prototypes of both wider and narrower gauge with the same tolerances such as Brunel's gauge, Japan Rail's narrow gauge and so on.
FiNescale Standard
The FiNescale standard in use for European prototypes is identical to 2mmFS, with the exception of a to-scale rail gauge of .
Appreciation
One major effect of the standard is to improve the appearance of the track as opposed to N scale, where it is overly tall.

- An early example of a 2 mm layout was Rydes Vale which was created in the 1960s by H. H. Grove and his son.
- The development of the Kineton exhibition layout by the Leamington & Warwick Model Railway Society was feature in series in the British Railway Modelling magazine running from February 2016.
