Creature Size
Each creature takes up a different amount of space. The table below shows how much space a creature of a particular size controls in combat. Objects sometimes use the same size categories.
| Size | Space | Space | Reach |
|---|---|---|---|
| (Upright) | (Long) | ||
| Fine | ¼ square | ¼ square | Close |
| Diminutive | ¼ square | ¼ square | 0 |
| Tiny | ¼ square | ¼ square | 0 |
| Small | ½ square | ½ square | 1 |
| Medium | 1 square | 1×2 squares | 1 |
| Large | 2×2 squares | 1×4 squares | 2 |
| Huge | 3×3 squares | 2×6 squares | 2 |
| Enormous | 4×4 squares | 3×8 squares | 3 |
| Gigantic | 5×5 squares | 4×10 squares | 3 |
Remember that each square is one meter across. This isn't always the space the creature occupies, but also typically includes the space that they control with physical attacks. Creatures that take up fractional spaces—those of Small size or smaller—can stack two creatures (if Small) or up to four creatures (if Tiny or smaller) in a single square.
Note that Large or larger creatures can typically attack foes at greater Reach.
Sharing Squares
A creature may enter another creature's square if there are two size levels difference between them, even if their combined sizes would exceed that square. For example, a Tiny creature could enter a Medium creature's square, or a Small creature could enter one of a Large creature's squares. Of course, if the combined sizes of the creatures does not exceed one square—such as two Tiny or smaller creatures in one square—then more creatures can occupy the same space.
