There are two measures of scale that seem to get used interchangeably between different manufacturers, groups of gamers and collectors. However where applicable I have also referred to the equivalent Railroad Scale as it is often possible to use buildings and models for tabletop gaming purposes.
- Ratio or Fraction (i.e. 1:72 or 1/72) – The number on the right shows how many units (Inches, centimetres it doesn’t matter) on the life sized object are equivalent to one on the model. So a 1/100th model that stands 1cm tall represents a real object 100cm tall.
- Size (i.e. 15mm or 28mm) – This is usually taken as the height of the average male figure and is measured from the bottom of the foot to eye level. But this isn’t standard across the industry and a lot of variation has resulted in “scale creep”.
|Fraction||Size||Common Applications(& Example Manufacturers)|
|1/268||6mm||Equivalent to 1/285 scale and 1/300 scales. Popular for ‘Micro armour’ games.|
|1/220||7mm||Z scale model railroad scale|
|1/200||8mm||20th Century armoured vehicles and aircraft|
|1/161||10mm||Fantasy, historical and science fiction. (Pendraken Miniatures)|
|1/160||10.06mm||N scale model railroad scale. Trees in this scale work well with 10-15mm models.|
|1/144||11.2mm||Official FOW Aircraft scale (Battlefront)|
|1/107||15mm||Popular Wargaming scale. Official FOW infantry scale (Battlefront / Old Glory / Peter Pig)|
|1/100||16.1mm0||TT Gauge. Alternative for 15mm|
|1/87||18.5mm||HO scale. HO Buildings are suitable for 15mm models (Hornby / Airfix / Revell)|
|1/80.5||20mm||Skirmish-level 20th Century Wargaming.|
|1/76||21.2mm||OO scale. Plastic miniatures and kits are available in this scale for aircraft, ground vehicles, and soldiers. (Hornby)|
|1/72||22.4mm||Popular for die-cast toys and plastic kits. (Revell)|
|1/64||25mm||S Gauge. Traditional Wargaming scale. Fantasy Wargaming, historical skirmish-level games, science fiction, and for use with role-playing games.|
|1/58||28mm||Sometimes referred to as "large" 25mm figures. Popular size for roleplaying models. (Games Workshop / Perry Miniatures)|
|1/54||30mm||Another scale used for pre-20th Century miniatures.(Enigma Miniatures)|
|1/50||32mm||LoTR’s models (Mithril Miniatures)|
|1/43.5||37mm||British O Gauge based on 7mm to the foot|
|1/48||33.5mm||US O Gauge which is 0.25 inches to the foot and referred to as "quarter inch scale". Popular for plastic aircraft kits. (Tamiya)|
|1/40||40mm||ACW & Napoleonic figures (Old Glory / Eureka Miniatures / North Star Figures)|
|1/38||42mm||Roughly corresponds to old B Range (Irregular Miniatures)|
|1/35||46mm||Plastic kits of armour. (Tamiya)|
|1/30||54mm||Sometimes called "Toy Soldier" scale|

I'm treating this as a work in progress (like so many other things) so please let me know if I've made any glaring errors or omissions. Once I'm confident this is accurate and comprehensive I'll post the table as a Page for ease of reference.
