Scales, Ratios and various sizes

How big?

Scales can be given as a ratio or a fraction (i.e., 1:64 or 1/64).  In this case 1mm on the miniature equals 64mm on the original .

Some scales (like GW) are listed as a certain height, ( 25mm, 28mm and 54mm are the most common ones)

Unfortunately none of the manufacturers can get there act together to standardize the scale. Some measure to the eye level and some measure to the top of the head. Fantasy and sci-fi ones also throw a wrinkle into the mixture. Usually, height scales measure to "eye height" while ratio scales measure to "head height"
