The team at Reaper Miniatures stick close to the 25mm Heroic scale for their regular line of products, a few exceptions do apply. These dimensions fall in line with the industry standard for most of board games that have heroes or monsters. The smallest piece is about as tall as a dime and the tallest miniature stands at about 18 inches.

Reaper Miniatures also produces some miniatures at the 54mm and 72mm scale and are often labeled as such in the name of that miniature. While the CAV line utilizes the N-Scale, much like what is apply to certain model train sets.
