HO or H0 is the most popular scale of model railway in the world.
According to the NMRA standard S-1.2 predominantly used in North America, in HO scale, 3.5 mm (0.1378 in) represents 1 real foot (304.8 mm); this ratio works out to about 1:87.1. According to the MOROP standard NEM 010 predominantly used in Europe, the scale is exactly 1:87. In HO, rails are usually spaced 16.5 mm (0.64961 in) apart which models the standard railroad gauge of 1,435 mm (4 ft 8 1⁄2 in).
The name HO is derived from the fact that its 1:87 scale is approximately half that of O scale which was the smallest of the series of older and larger 0, 1, 2 and 3 scales introduced by Märklin around 1900. In most English-speaking markets it is pronounced "aitch-oh" and written with the letters HO today, but in German it is pronounced "hah-null", and still written with the letter H and numeral 0.
Currently, HO is the most popular model railroad scale in both continental Europe and North America, whereas OO scale (4 mm:foot or 1:76.2 with 16.5 mm track) is still dominant in Britain.
There are some modellers in Great Britain who use HO scale. For them, the British 1:87 Scale Society was formed in 1994; it publishes a quarterly journal with news, views, and practical advice for modellers and collectors. A magazine, Continental Modeller, focuses on the railways of other countries, including America and Europe, and has extensive coverage of HO scale layouts.
Today, HO locomotives, rolling stock (cars or carriages), buildings, and scenery are available from a large number of manufacturers in a variety of price brackets.
