The scale of figure kits varies, but as of 2008, 1/8 seems to be the predominant scale. Prior to 1990 the dominant scale was 1/6. This scale shrink coincided with the rise in material, labor, and licensing costs. Other scales, such as 1/3, 1/4, 1/6, 1/7 also exist, but are less common. Larger kits (1/3, 1/4, etc.) generally command higher prices due to the greater amounts of material required to produce them.
