The models all come in different sizes. In order to be compatible with most table top and board games we measure the model size by the diameter of the base it is on. This assists with compatability with the grid size used in your tabletop game. Here are the standard sizes we offer: Medium: 1" Large: 2" Huge: 3" Gargantuan: 4" Colossal 5" or more As for scale, we do our best to keep the models at a 28mm scale common to RPG games like Dungeons & Dragons. Due to carrying models from numerous artists who sculpt in various scales and styles we have opted to standardize models by the base they are on or fit on. The height of the model varies but can be seen when compared to the base the model is on. If you have a very specific height, scale, or size request you are always welcome to reach out to us and we will gladly work with you. Remember, when in doubt reach out :)
