RUSTLY

Rust Maps

Every Rust world is generated from two numbers — a seed and a size. Here's how that works, what the sizes and biomes mean, and how to read a map at a glance.

How Rust maps work

Rust doesn't ship hand-made maps. Every world is procedurally generated from a seed (a number) and a world size (in metres). The same seed and size always produce the exact same world — the same island shape, monuments, roads and rivers — on any server, which is why seeds get shared and copied.

That also means maps are tied to the wipe. When a server changes its seed or size — usually at the monthly force wipe — the whole world changes with it. A seed is worth knowing for one wipe, not forever.

Map sizes at a glance

SizeAreaBest for
30003 × 3 kmTight and fast — solos, duos and low-pop servers. Monuments are close together, so travel and roams are short.
35003.5 × 3.5 kmA common default. Enough room for a healthy population without the map feeling empty.
40004 × 4 kmThe typical high-pop vanilla size — space for lots of bases and every monument, without huge dead zones.
45004.5 × 4.5 kmBig-server territory. More monuments and more room to hide a base, but longer travel to fights.

Servers can pick any size from 1000 to 6000, but almost all sit between 3000 and 4500.

The four biomes

Arctic

Bright white, usually a band along one edge of the map.

Tundra

Pale blue-green with darker pine cover.

Temperate

Green, the largest share of most maps.

Arid

Sandy tan/yellow, usually opposite the arctic edge.

Frequently Asked Questions

How do Rust maps work?expand_more

Every Rust world is procedurally generated from a seed and a world size. The same seed and size always produce the same map, so worlds are shared and copied by their seed rather than drawn by hand.

Do Rust maps change?expand_more

Yes — a server's map changes whenever it changes its seed or size, which most do at the monthly force wipe. A given map only exists for that wipe.

How big is a Rust map?expand_more

It depends on the server's world size. Most run between 3000 and 4500 metres across — a 4000 map is 4 km × 4 km. Sizes can range from 1000 to 6000.

How many biomes are in Rust?expand_more

Four: arctic, tundra, temperate and arid. They band across the map from frozen to desert, and the biome you start in shapes your early game.
