Minecraft spiral staircase generator step by step
Pick the well size and the height and get the staircase layer by layer: each layer is one step. A 3 × 3 spiral staircase 24 high takes 48 blocks, with 8 steps per turn and 7 blocks of headroom. Add a round wall for a tower, then build it or export it.

Spiral staircase sizes at a glance
Block counts for a 24 block climb. The steps per turn decide how steep it is and how much headroom you get.
How to use it
4 steps
- Set the well size (3 × 3 is the compact classic) and the step width; everything inside the steps is the centre pillar.
- Set the height in blocks. Each layer holds exactly one step, one block above the last.
- Step through the layers from the bottom: place the pillar and that layer's step. Use stair blocks facing the climb to walk up without jumping.
- Add a wall for a tower, then use build mode on your phone or export a schematic.
Questions builders ask
How do I make a spiral staircase in Minecraft?
Build a pillar in the middle and place one step per layer around it, each one block higher than the last. In a 3 × 3 well the 8 blocks around a 1-block pillar are the steps, so one full turn is 8 steps and climbing 24 blocks takes 48 blocks in total. Put a stair block on each step, facing the way you climb, so you can walk up without jumping.
Will I hit my head on the step above?
No. A step has the step one turn higher straight above it, 8 layers up in a 3 × 3 well, so there are 7 free blocks of headroom. You need 2. Wider wells have more steps per turn: 9 in a 5 × 5 well with 2-wide steps, 19 in a 9 × 9 well.
What size spiral staircase should I build?
3 × 3 is the compact classic (one step per block around a single pillar). 4 × 4 has a 2 × 2 pillar and 8 steps per turn. 5 × 5 with 2-wide steps (77 blocks for 24 high) is comfortable for a tower. Use 7 × 7 or more for a grand staircase.
Which way does it turn?
The generator climbs clockwise seen from above, starting on the east side. To turn the other way, build the layers in a mirror image, or rotate and mirror the schematic when you paste it.
Can I put a wall around it for a tower?
Yes, switch on "Round wall around it". The 5 × 5 staircase then gets a round wall and is 7 × 7 on the outside: 461 blocks for 24 high, wall included.
