:''You may be looking for size of [[clothing]], [[armor]], the dimensions of a [[tile]], or the [[List_of_creatures_by_adult_size|list of creatures by size.]]''

'''Size''' is a measure of how big a [[creature]] or [[item]] is, as volume in cubic centimeters{{cite forum|30026.msg831163#msg831163}}, and called {{token|BODY_SIZE|c}} or <code>[[Item_definition_token|[SIZE]]]</code> in the [[raw file]]s.

Size has many important effects on the game, many through its direct effect on item [[weight]], one of the many [[material science|material properties]] in Dwarf Fortress. Size directly affects such things as [[Weapon#Size|which weapons]] your dwarves can equip, [[butcher]]ing returns, [[storage]] limits, and [[combat]] effectiveness for both creatures and weapons.

As far as in-game location and movement, size does ''not'' matter; one item or creature always is located in just one tile, regardless of size. If a [[path]] is open to a dwarf, it's open to every other creature in the game, no matter how large. A thousand full grown [[dragon]]s can occupy a single square (so long as [http://www.bay12games.com/media/b12_call_1_transcript.html 999 of them are lying down]), and a common [[rabbit]] blocks a [[door]] or fills a [[cage]] as completely as a gigantic [[bronze colossus]].

__TOC__
== Game mechanics ==
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.

Internally, all custom size numbers are rounded down to the nearest multiple of 10 - thus, if you define an item with <code>[SIZE:15]</code>, it will actually behave as if you had specified <code>[SIZE:10]</code>.{{cite forum|169696.msg8300987#msg8300987}}

The weight of [[creature]]s 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.

== Buildings ==
The {{token|DIM|building}} [[building token]] defines the size of a [[workshop]] or [[building]] in [[tile]]s. 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'' [[material]]s 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 {{token|BODY_SIZE|c}} tokens, often with multiple tokens to set their base size at certain ages.

Bodysize determines several things:
* Average [[butcher]]ing yields.
* How much [[damage]] they can absorb (along with morphology).
* How much damage they can inflict in melee (along with morphology and attack definition [[creature token|token]]s).
* For creatures that can wear equipment ({{token|EQUIPS|c}}).
:* What size of equipment a creature can wear; clothing and armor are sized for a specific species and only creatures with a species base size near that size can wear them, an individual creature's actual size does not matter for this.
:* Weapons have a minimum size that a creature must be to wield them ({{token|MINIMUM_SIZE|wp}} and {{token|TWO_HANDED|wp}}), tissue layer thickness not included, see below.

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 {{token|BODY_APPEARANCE_MODIFIER|c}}) tokens that allow them to vary in height, width, or length, which they can maybe [[Genetics|pass on]] to children.
The following add to size, but are not included when determining how weapons are wielded.
* Muscle mass, determined by its [[strength]] attribute (a thin dwarf with ~44210 size will be ~64210 once they become unbelievably strong), due to muscle having {{token|THICKENS_ON_STRENGTH|tissue}}.
* Fat mass, due to {{token|THICKENS_ON_ENERGY_STORAGE|tissue}}.{{verify|untested, seems like it should, and a bug if it doesn't}}

Creature sizes range 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.

== Items ==
Most items defined in the [[raws]] require a <code>[SIZE]</code> token, each class of item has its own: for instance, {{token|SIZE|ammo}} for [[ammo]], {{token|SIZE|wp}} for [[weapon]]s, {{token|SIZE|tool}} for [[tool token|tool]]s, 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:

[[File:Roc_Size.png|frame|Estimated size comparison between a roc and a dwarf.]]

'''Rocs''' are gigantic [[megabeast]]s taking the form of colossal birds of prey. These [[creature]]s reach their max size at only 20 years, and once they hit that age, they become the [[List of creatures by adult size#end of list|largest creatures]] in the game who are capable of flight. As megabeasts, rocs are also found in lairs, stealing items from nearby [[site]]s and generally harassing [[civilization]]s. Their lair is often littered with the loot they've amassed, as well as a number of [[nest box]]es for them to use. All rocs are born with Talented [[skill]] in [[Combat skill|fighting, biting, kicking, dodging]] and [[Observer|observing]].

Rocs are naturally formidable opponents; they are twice the size of a [[titan]] and are able to attack your [[dwarves]] from above, quickly turning them into little bearded shreds with their talons. However, when compared to their fellow megabeasts, rocs are arguably the least powerful of the four. Unlike other megabeasts, rocs are susceptible to both pain and over-exertion, and they also lack the danger posed by the [[Dragonfire|fire breath]] of a [[dragon]], the multi-attacks of a [[hydra]] or the inorganic armor of a [[bronze colossus]]. That being said, rocs are not to be underestimated, for their sheer size makes them a grave threat to a fortress.

Despite their monstrous size, rocs are just as vulnerable to [[cage]] [[trap]]s as any other creature. In the event the player succeeds in capturing one, they can be [[Animal trainer|trained]] and turned into war or hunting beasts or, if female, be [[pasture]]d at a [[nest box]] to lay gigantic [[egg]]s – rocs lay the largest eggs in the game, each over thrice the size of a dwarf, but egg size currently plays no role. Rocs only lay 1-2 eggs at a time, which would make them subpar targets for [[egg production]] along with the size of them making hauling the eggs a time-consuming process, though one may choose to ignore this fact for the bragging rights of having your dwarves dine on the eggs of a colossal mythical bird.

Along with dragons, rocs are one of the megabeasts in possession of the {{token|CHILD|c}} token, meaning they can become fully domesticated without [[modding]]. (Outdated: However, due to being megabeasts, rocs are perpetually hostile to your military [[squad]]s and must be kept separated from your soldiers, otherwise they will kill each other on sight.{{bug|10731}}) This is almost certainly outdated information according to [https://www.reddit.com/r/dwarffortress/comments/111mnh1/tame_dragon_not_attacking_military/ this] Reddit post. Trained or tame rocs likely won't attack friendly creatures, even if they're military, guests etc.

Some dwarves [[Preferences|like]] rocs for their ''awe-inspiring size'' and their ''dedication to their young''.
