v50.15 · v0.47.05 This article is about the current version of DF.Note that some content may still need to be updated. |
- You may be looking for size of clothing, armor, the dimensions of a tile, or the list of creatures by size.
Size is a measure of how big a creature or item is, as volume in cubic centimeters[1], and called [BODY_SIZE] or [SIZE] in raw files.
Size has many important effects on the game, many through its direct effect on item weight, but as material properties go, its implementation is sometimes underwhelming - witness the incredible compression of matter, space, and time that is the QSP. When even multiple full grown dragons occupy a single square, size becomes a little difficult to contextualize. It doesn't help that a bronze colossus fits in a basic wooden cage (although, a fire man fits in it too).
Size directly affects such things as which weapons your dwarves can equip, butchering returns, storage limits, and combat effectiveness for both creatures and weapons.
Size is used to calculate an item's weight, along with the density of the underlying material(s):
- Weight (in Γ) = Density (in kg/m3) * Size (in cm3) / 1,000,000 (cm3 in a m3)
Through weight, the size of an item has further ramifications in the game, such as hauling speed, pressure plate activation, impact momentum, weight restrictions, and so forth.
The weight of creatures is calculated from the densities and sizes of the layers of their body parts, which currently results in corpse weights that are about 1/3 heavier than expected.
Internally, all custom size numbers are rounded down to the nearest multiple of 10 - thus, if you define an item with [SIZE:15], it will actually behave as if you had specified [SIZE:10].
Buildings
The [DIM] building token defines the size of a workshop or building in tiles. This differs from creatures and items in that a building doesn't have a weight, and it's not in cm³, of course.
Creatures
When it comes to creatures, size is a rough stand-in for weight since standard flesh weighs about one gram per cubic centimeter. However, in the typical complexity of Dwarf Fortress, there are a number of other materials animals can include (ivory, hair, horn, shell, etc.) which have their own densities, shifting a creature's actual weight relative to its size, sometimes significantly (elephant tusks weigh a lot). Creature size is determined by [BODY_SIZE] tokens, often with multiple tokens to set their base size at certain ages.
Bodysize determines several things:
- Average butchering yields.
- How much damage they can absorb (along with morphology).
- How much damage they can inflict in melee (along with morphology and attack definition tokens).
- For creatures that can wear equipment (
[EQUIPS]).
- What size of equipment a creature can wear; clothing and armor are sized for a specific species and only creatures near that size can wear them.
- Weapons have a minimum size that a creature must be to wield them (
[MINIMUM_SIZE]and[TWO_HANDED]).
The actual size of an individual creature is the result of different effects:
- The base BODY_SIZE for the species of creature.
- The age of the creature; most creatures are born at minimum size, and grow to a maximum.
- Some, like dragons and most species of snake, grow throughout their entire lifetime, and may not live long enough to reach the maximum.
- Inheritance; many creatures have
[BODY_APPEARANCE_MODIFIER]) tokens, that allow them to vary in height, width, or length, which they can pass on to children. - Muscle mass, determined by it's strength attribute (a thin dwarf with ~44210 size will be ~64210 once they become unbelievably strong), due to muscle having
[THICKENS_ON_STRENGTH]. - Fat mass, due to
[THICKENS_ON_ENERGY_STORAGE].[Verify]
Creature sizes range from 1 (small insect vermin) to 200,000,000 (giant sperm whales, the largest creature in the game). See List of creatures by adult size for details.

Items
Most items defined in the raws require a [SIZE] token, each class of item has its own: for instance, [SIZE] for ammo, [SIZE] for weapons, [SIZE] for tools, and so on.
Item types not defined in the raws also have a size which can be determined from their weight and material density, using DFHack, or code debugging. Some assorted item type sizes, and their storage capacity when applicable:
