'''O14''' is a set of [[model railway]] standards for accurately modelling {{RailGauge|2ft}} [[narrow-gauge railways]] in 1:43.5 ([[7 mm scale]]) using {{convert|14|mm|in|3|abbr=on}} gauge track.

The first published O14 standards appeared in ''[[Model Railway Constructor]]'' magazine, September 1951. The article was titled "A Narrow Gauge Layout" and was by Douglas Clayton. He advocated [[H0 scale|HO]] standards, less 2.5mm coupled with coarse scale [[OO gauge|OO]] wheelsets set to 12.5&nbsp;mm back to back. A subsequent article in 1953 provided details of his layout. Very little more happened regards the development of O14 until [[Roy C Link]] published a new set of standards (1993 — revised 1994) in his magazine ''[[Narrow Gauge and Industrial Railway Modelling Review]]''. They were developed for his range of O14 kits — now produced by David Janes under the name KBscale. They are based on the proven 4&nbsp;mm scale [[EM gauge|EM]] standards (BRMSB) and are reasonably close to exact scale especially considering the variations to be found in prototype nominal {{TrackGauge|2ft}} gauge railways.

This scale/gauge combination is managed by the O14 Group (an informal web based society dedicated to finescale 7mm narrow gauge modelling) and supported by the [[7mm Narrow Gauge Association]].

==Related scales==
[[O gauge]] is used for modelling standard-gauge railways in [[7 mm scale]], with [[ScaleSeven]] the accurate scale and complementary set of standards to O14. Other [[7 mm scale]] narrow-gauge [[model railway]] gauges include: [[O16.5]], [[On30]] and O21.
