The Tiny trait marks creatures, PCs, and items whose size falls below a standard 5‑foot square. Tiny creatures occupy less than 5 feet of space (roughly 1–2½ feet across), have 0‑foot reach by default, and multiple Tiny creatures can share a single 5‑foot square.
Mechanically, Tiny size affects space, reach, movement through other creatures’ spaces, and Bulk interactions, while leaving most other stats unchanged. A Tiny creature:
Has 0‑foot reach, so it must be in the same space as a target to make most melee Strikes unless using a reach weapon sized for Tiny creatures.
Can occupy the same space as a larger creature, and at least four Tiny creatures can fit in one 5‑foot square.
Can enter other creatures’ spaces more freely than larger creatures, which is crucial for Tiny PCs whose melee Strikes would otherwise have no valid targets.
Flanking rules don’t change: Tiny creatures flank exactly like any other creature—you and an ally must be on opposite sides of an enemy, with a line drawn between your centers passing through opposite sides or corners of the enemy’s space. Being inside an enemy’s space does not count as flanking by itself. To flank in melee, a Tiny creature usually needs a reach weapon sized for Tiny users (its reach is typically 5 feet less than the listed value, so a 10‑foot reach weapon gives a Tiny wielder 5‑foot reach).
For equipment, Tiny weapons and items usually have the same stats but half the Bulk compared to Small/Medium versions, while Bulk conversions and negligible items scale differently. Rules specify that a Tiny creature treats 10 negligible‑Bulk items as 1 Bulk, reflecting how small objects become meaningful loads at that scale. General carrying capacity still uses the standard “5 + Strength modifier” and “10 + Strength modifier” Bulk thresholds for encumbered and maximum load, but Tiny creatures often hit those limits faster because more things count as real Bulk to them.
Tiny PCs (such as sprites or awakened animals) follow special guidance: they can enter other creatures’ spaces, often ride allies, and use the same core three‑action economy, but need to manage 0‑foot reach, flanking constraints, and tighter Bulk limits carefully. Starfinder’s Tiny creatures follow the same general pattern: about 1–2 feet in size, four per square, sharing space easily while relying on positioning and reach to engage larger foes.
In the Starfall Galaxy, Tiny isn’t “small”—it’s equipment scale. Tiny species, micro‑drones, awakened vermin, and pocket‑rigged synthetics move through the galaxy in spaces most people call “vent shafts” or “places you drop a wrench and never see it again.”
A Tiny body can walk along cable bundles behind bulkheads, sprint across computer banks without touching the floor, or hide behind a single loose plating panel while heavy armor troops stomp past. Everyone else sees hallways and rooms; Tiny creatures see tunnels, ledges, and cover in places that weren’t designed as terrain at all. At the same time, the Starfall proverb holds: “If the ship has a hole, something Tiny can get through it before you can patch it.”
Space and sharing
Tiny creatures take up less than a full 5‑foot square and can share squares freely with each other and with larger creatures. At least four Tiny creatures fit in one square under default rules.
0‑foot reach
Most Tiny creatures have 0‑foot reach, meaning they can’t attack adjacent squares with ordinary melee weapons; they must enter a target’s space to make melee Strikes. Reach weapons lose 5 feet of reach in Tiny hands, so a typical 10‑foot reach weapon gives a Tiny wielder 5‑foot reach—enough to attack from an adjacent square without occupying the enemy’s space.
Moving through other creatures
Tiny PCs can move into and through the squares of larger creatures more freely than normal, which is vital since they often need to be inside a foe’s space to attack. This also means they are more exposed to effects that target spaces (bursts, blasts, hazards) that ignore creature boundaries.
Flanking rules unchanged
The flanking definition is identical: you and an ally must be on opposite sides of a foe, with a line between your centers passing through opposite edges or corners; being inside the target’s space by itself doesn’t count.
Tools for Tiny flankers
Reach weapons sized for Tiny creatures (like a “shortened” long spear or whip) allow a Tiny PC to stand in an adjacent square and flank normally.
Rogue feats like Gang Up can let Tiny rogues treat enemies as flanked if both they and an ally have the foe within reach, regardless of precise opposite‑side positioning.
Tiny PCs thus often build around reach, mobility, and teamwork to consistently apply flanking and precision damage.
Bulk adjustments
Tiny creatures use the normal Bulk limits (5 + Strength modifier encumbered, 10 + Strength modifier maximum), but they: Treat 10 negligible items as 1 Bulk. Use equipment that typically has half the Bulk of Small/Medium equivalents, though cost and stats are usually the same.
Practical consequences
In practice, Tiny characters hit carrying limits quickly unless they keep Strength reasonable or delegate hauling to companions, mounts, or drones. Even coinage and everyday gear stop being “weightless” abstractions and become real logistics to manage.
