The most commonly found full model scale is 28mm scale as this is the most common scale used by gaming companies in recent years, although these models can be closer to 32mm scale or even 35mm scale due to scale-creep. Additional to scale-creep, often models that are sold and marketed as being a 28mm scale have anatomical features such as hands and heads that are out of proportion with the rest of the model. Originally a result of limitations fine details in metal, this is commonly done as a stylistic choice to create a more imposing or impressive looking character, referred to as "heroic" scale. Models made to be exactly in scale are referred to as "true" scale. Heroic scale and scale-creep are more common in sci-fi and fantasy models than historical or military war game models, although true scale models can still sometimes suffer from heroic proportions.
