		+	== Bodysize ==
		+	Creature-specific size is known internally as '''bodysize''' (from the {{tt\|[BODY_SIZE]}} [[creature token\|token]]). When it comes to creatures, size is a rough stand-in for [[weight]]: standard flesh weighs one gram per cubic centimeter. However, in the infinite complexity of ''Dwarf Fortress'', there are a number of ''other'' [[material]]s animals internalize ([[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''). Bodysize also determines average [[butcher]]ing yields, (along with morphology) how much [[damage]] they can absorb, and (along with morphology and attack definition [[creature token\|token]]s) how much damage they can inflict in melee. On {{tt\|[HUMANOID]}} creatures, size also directly determines what kind of equipment a creature can wear: large, small, normal, or none at all.
		+
		+	The actual size of a creature is the result of three different effects, one basic and two that are highly variable. First and most basic is the average maintained across an individual species of creature. The second is the [[age]] of the creature: most creatures are not born anywhere near their maximum size, and instead must grow into it; some, like most species of snake, grow throughout their entire lifetime, and probably will not live long enough to reach it. The third is inheritance: version 0.31.1 introduced [[genetics]], allowing creatures to inherit part of their size from the appearance, specifically the height and girth, of their parents.
		+
		+	Actual creature sizes go from 1 (small insect [[vermin]]) to 200,000,000 ([[giant sperm whale]]s, the largest creature in the game). See [[List of creatures by adult size]] for details. The average size set for a dwarf is 3,000, 15,000, and 60,000, the size of a baby, child and adult respectively.

		+	== Mechanics ==
		+	* '''Constructed items''': [[item definition token\|Item definition files]] for [[industry\|industry-crafted]] items are specific to various classes of items: for instance, [[ammo]] has its own [[ammo token\|ammo definition tokens]], as does [[armor token\|armor]], as do [[tool token\|tool]]s, and so on. A {{tt\|[SIZE]}} token is a field required in all of these definitions.
		+
		+	Bars lack a defined size token in the raws. They have a size of 600 cm<sup>3</sup>, which can be deduced from the equation listed above using their weight and the densities of their corresponding materials. This is consistent with 5 bars fitting inside a [[Container#Quick_Reference\|3000-capacity bin]]. The dimensionless unit of '150' products per bar, primarily of use for soap, suggests that each use of soap should diminish the size of the item by 4cm<sup>3</sup> (i.e. 600cm<sup>3</sup>/150). Whether this is true is currently untested.{{verify}}
		+
		+	* '''Inorganic items''': [[Stone]]s, [[gem]]s, and [[ore]]s appear to have a default, hard-coded size that is applied to all items of that class; thus there is no direct [[inorganic material definition token]] for it.
		+	* '''Plants''': There is no size [[plant token]].
		+	* '''Buildings''': The {{tt\|[DIM:#:#]}} [[building token]] defines the by-[[tile]] size of a [[workshop]] or [[building]].
		+	* '''Creatures''': The [[creature token]] version of {{tt\|[SIZE]}} is the <tt>[BODY_SIZE:#:#:#]</tt> token, which accepts three variables. The first number is age in years; the second additional age is in days. The third number is its size in cm<sup>3</sup>. Multiple ages and multiple {{tt\|[BODY_SIZE]}} tokens are used to constrain a creature's [[age]]-based growth pattern and final size. Genetics is accounted for by a {{tt\|[BODY_APPEARANCE_MODIFIER]}} token tagged for {{tt\|LENGTH}} and/or {{tt\|HEIGHT}}. For instance, genetic variance in the [[anaconda]] is defined so: {{tt\|[BODY_APPEARANCE_MODIFIER:LENGTH:90:95:98:100:102:105:110]}}. Each interval value is genetically inherited, and each interval value has an equal chance of occurring; the numbers are the percentage of the base size a creature in the interval will be.
