Size

Size represents a creature’s physical scale and plays an important role in determining how it interacts with the world. It affects movement, combat reach, available space, line of sight, environmental navigation, and the effectiveness of certain abilities or equipment.

Each creature has a size category ranging from the minuscule to the titanic. These categories define how much space the creature occupies on the battlefield and how far it can reach.

Size Categories

Size Modifier	Category	Space (ft.)	Reach (ft.)
–5	Infinitesimal	Special	0
–4	Microscopic	Special	0
–3	Minuscule	5 x 5	0
–2	Tiny	5 x 5	5
–1	Small	5 x 5	5
0	Medium	5 x 5	5
+1	Large	10 x 10	5
+2	Huge	15 x 15	10
+3	Enormous	20 x 20	15
+4	Titanic	25 x 25	20
+5	Behemoth	30 x 30	25

Moving Through Smaller Spaces

A creature normally requires space equal to or larger than its size category to move freely without penalty.

Squeezing: If a creature attempts to move through an area that is 5 feet narrower than its space, it can still move, but at half speed in that area.
Combat Penalties: Being in a space narrower than the creature’s size imposes a –5 penalty to AC and all attack rolls.

Size and Stealth

When attempting to Hide or use Stealth, apply your Size Modifier to the Stealth check result. Smaller creatures find it easier to hide, while larger creatures are naturally more visible:

Smaller creatures: Subtract the negative modifier from the check (effectively adding to the total).
Larger creatures: Subtract the positive modifier from the check.

Example:
A Small creature (Size Modifier –1) adds +1 to its Stealth checks.
A Huge creature (Size Modifier +3) suffers a –3 penalty to its Stealth checks.
