====== Size Categories ======
^ Size Category ^ Reach     ^ Space        ^
| Tiny          | 0 feet    | 1 square     |
| Small         | 5 feet    | 1 square     |
| Medium        | 5 feet    | 1 square     |
| Large         | 10 feet   | 2x2 space    |
| Giant         | Special   | Special      |

===== Tiny =====

A tiny creature is one that does not fully occupy a 5 foot square. They can only attack creatures who share a square with them. Multiple tiny creatures can share the same square without needing to make a check. Pixies and house cats are iconic tiny creatures.
===== Small =====

A small creature fully occupies a 5 foot square but is significantly smaller than a typical human. Mid-sized dogs or dwarves are iconic small creatures.
===== Medium =====

A medium creature is the size of a typical human.
===== Large =====

This represents something significantly larger than a typical human, while not being excessively massive. Orcs and trolls are iconic large creatures.
===== Giant =====
^ Reach    ^ Space       ^
| 15 feet  | 3x3 space   |
| 20 feet  | 4x4 space   |
| 25 feet  | 5x5 space   |
| 30 feet  | 6x6 space   |
| 35 feet  | 7x7 space   |
| 40 feet  | 8x8 space   |

The size category of “giant” creatures is a variable definition meant to encompass creatures larger than what a typical “large” creature entails. You can increase a creature’s size by 1 step above large by adding 5 feet to its reach and increasing its space by 1x1. Giant creatures typically start around the size of a walrus or an elephant.
Note: Giant is typically stated as “Giant (# x # space, X feet. reach)”. If a creature is just “Giant” it is assumed to be “Giant (3x3 space, 15 feet. reach)”.

===== Atypical Reach =====

Some creatures have different reaches than those listed. This is often due to some oddity of their biology- the above size categories assume a humanoid frame. A horse, for example, only has a reach of 5 feet. This is because they are a quadruped rather than a 12 foot tall orc.

===== Equipment & Size =====

You can use equipment so long as it is within a size category of you. A small creature can use things designed for a medium, small, or tiny creature and a large creature can use stuff for a medium, large, or giant creature. It might require a little modification but it’s generally accepted that a human and a halfkin can make use of the same equipment. When in doubt- players can freely swap equipment unless it would be ridiculous.
