Building stability
Pick what your build stands on and what you build with, and see how high and how far out it holds before it turns red.
You can build 8 high (≈32 m) and 5 out to each side.
Height: tested in gameReach: calculated
Fainter pieces are closer to the limit – they show yellow or orange in game. The gold row is the height you pick below.
At ground level you can stick out 5 pieces.
TipA stone foundation would take you 10 high and 7 out.
Rules that matter
- 1Only the anchor sets the heightAsh gives 5 pieces up, oak 8, stone, Castle Kit and Kharidian 10. What the walls are made of doesn't matter, and bracing doesn't add height.
- 2Wall material sets the reachStone walls lose more stability sideways than ash or oak. For wide builds, use a stone foundation with oak walls.
- 3Beams make new anchorsA vertical beam that touches the ground counts as a foundation of its own tier. Thick and thin beams are equal. Horizontal beams between walls don't help.
- 4Reach shrinks as you go upEvery piece up costs stability, so you can build less far out on higher floors.
- 5Angled beams need a grounded postA slanted beam must end in a vertical beam that reaches the ground – look for the blue connection dot.
- 6Watch for false anchorsBeams on rocks or ledges can look connected without being anchored.
- 7Use foundations, not floors, at the bottomFloor tiles in place of foundations float and stay unstable.
- 8Neighbours help a littleA foundation next to a better one gets some of its stability – an ash foundation beside oak reaches about one less than oak.
- 9Leave room for the roofBuild the roof from the corner and the bottom up, put beams or posts under it, and keep the building 1–2 floors under the max so the roof can reach.
- 10Read the preview colourGreen is stable; yellow then orange means you're near the limit; red can't be placed. With stability turned off when the world was made, none of this applies.
How it's calculated
Every piece has a stability value. The piece touching the ground starts with its own (ash 1515, oak 2415, stone 3215 for foundations and beams). Each piece placed on top costs 300; each piece out to the side costs 300 × its sideways loss (1.5 for ash and oak, 2.5 for stone walls, 1.25 for stone beams). A piece can go down while at least 10 is left.
Measured means players have tested the number in game. Calculated comes from the same model, which matches every measured limit but hasn't been tested in game for that combination yet.
