HO is a gauge (scale) for model trains. The name HO comes from the fact that it represents a reduction of half from the earlier O gauge ("Half O"), which was more popular in Europe. The ratio for HO gauge equipment is 1:87 which means that the HO tracks are 16.5mm apart, or 1/87th of a standard train track (1435mm). In Europe, an almost exactly the same scale is called OO (pronounced "Double O"), even though it is much closer to half of O scale than double it (it is actually called "Double O" because there are two O's (OO) in the scale name).

∙ 12y agoHO is derived from the fact that its 1:87 scale is approximately half that of O or 0 scale, which was from the original numerical scale. The 0 scale was crated as a smaller version of the 1 scale, then the H0 scale was created later, halving the 0 scale.
