Creature Size and Space

Each creature occupies and controls a different amount of space in combat. Objects sometimes use the same size categories:

| Size | Space | Example | | Tiny | ½-square cube\ | Cat | | Small | 1-square cube | Goblin | | Medium | 1-square cube | Human (Average) | | Large | 2-square cube | Dire wolf | | Huge | 3-square cube | Tyrannosaurus | | Gargantuan |

4-square cube

| High dragon |

Reach: You can reach virtually anything within 1 square of you.

Zone of Control: You can't move through the space of a creature that doesn't permit you to do so, unless the creature is incapacitated, Tiny, or at least two sizes larger or smaller than you.

No Sharing Spaces: You can't willingly end your move in the space of another creature, unless the creature is incapacitated, Tiny, or at least two sizes larger or smaller than you.

Squeezing Into a Smaller Space: A Tiny, Medium, Large, Huge, or Gargantuan creature can squeeze through an opening no narrower than half the width of its space. A Small creature can squeeze through an opening as narrow as ⅓ square.

While squeezing, a creature must spend 1 extra square of movement for each square it moves there, and it has disadvantage on Fighting tests. Fighting tests against the squeezing creature have advantage.

Square-Cube Law: A Tiny creature can use its Agility in place of its Strength when it makes a test to climb, jump, or passively determine the maximum distance it can jump (see Jumping, Climbing, Swimming).
