All About Scales

What is ‘scale’?

The size of a model or miniature relative to whatever it is a representation of is known as its scale. Scales can be defined in a variety of confusing ways, for a variety of historical reasons. For example, models of historical vehicles are often defined simply as “1/48”, implying that the model is a forty-eighth the size of the original. Wargaming figures instead regularly use the ‘eye height’ measure, where a ‘28mm’ model is a model scaled such that a human would be 28mm tall up to their eyes (presumably to avoid the difficulty of accounting for fancy hats). Model railway scales are more complicated still.

This page serves as a reference to allow you to easily convert between ‘equivalent’ scale representations, and to record common uses of those scales.

Large amounts of the information contained herewithin is taken from http://theminiaturespage.com/ref/scales.html upon which this serves to update and elaborate. That page has been an invaluable resource to me over the years and I highly recommend you check it out for more details about scale conversion.

Note: Many conversions shown here are slightly rounded, particularly if the equivalent is close to a commonly-used term for a scale.

For instance, I have merged 1/100 and 15mm scales (which are more strictly 16.1mm and 1/107 respectively), because they are so close as to be indistinguishable.

1/X scale Xmm eye height X to the foot Model Railway Uses
Tiny       (to be expanded)
1/2400 0.67mm     Modern naval miniatures including WWI, WWII, and beyond.
1/1250 1.29mm     Naval miniatures for the most part. Used by actual militaries for training.
1/1200 1.34mm 1 inch to 100 feet   UK/USA alternative to 1/1250.
1/800 2mm     Probably the smallest scale where you field units of actual people, although at this scale, units are generally textured blobs, a whole formation to a base.
1/450 3.58mm   T scale The tiniest working model railways. Sometimes referred to as 1/480 instead.
1/270 6mm     At this scale you start to actually get individual figures for people (rather than just bumps), although they may still be moulded together onto a strip. Also used for sci-fi vehicles such as FFG’s X-wing Miniatures Game, Games Workshop’s new Adeptus Titanicus. Old Epic 40k was roughly 6mm too.
1/220 7mm   Z scale  
1/160 10mm   N scale Comparatively large number of models available from different genres, including Games Workshop’s old Warmaster.
1/144 12mm     Popular scale modelling scale. Gundam’s High-Grade (HG) and Real-Grade (RG) models are normally made to this scale.
1/100 15mm     Popular scale for all sorts of wargaming, with both individual infantry figures and a wide variety of vehicles availables. Flames of War models are at this scale, as are Gundam’s Master-Grade (MG) models.
1/87 18.5mm   HO scale Also used for diecast civilian cars.
1/80 20mm     Some wargaming figures are available as this scale.
1/76 21.2mm   OO scale British alternative to HO, diecast cars also available.
1/72 22.4mm 1 inch to 6 feet   Primarily used for scale models of vehicles and planes
1/64 25mm   S scale Original scale of early Games Workshop (/Ral Partha) models.
1/56 28mm     Most popular wargaming scale, used for Warlord’s Bolt Action, Napoleonics (including Perry Miniatures variety of plastic kits), and, Games Workshop’s mainline games (although they increasingly creep upwards). Although closer to 1/58, vehicles at this scale are increasingly being sold as 1/56.
1/48 32mm   O scale (USA) Relatively common scale for a variety of purposes, both in scale modelling and wargaming. Star Wars Legion uses this scale.
1/43.5 37mm 7mm to the foot O scale (UK) Die-cast cars available.
