The scale of a figure is often described in millimeters, for example one of the most common scales is 28 mm. While a model may be described as 28 mm the actual height of the model may be different. This is because of a number of factors such as manufacturer, model proportion, method of measuring the model, the model's pose, and what sort of man the model is meant to represent. A manufacturer might advertise its figures as 28 mm, but their products may be over 30 mm tall. Manufacturer's use of scale is not uniform and can deviate by as much as 30%. Some manufacturers measure figure height from the feet to the eyes rather than the top of the head; therefore, a figure that is 30mm to the top of its head could be considered to be a 28mm miniature.
