Minecraft Torus Generator (Java & Bedrock)
A torus is a ring-shaped donut lying flat. A 31-block torus with a 7-block tube uses 2,948 blocks when filled; hollow saves most of that.

Blocks for common torus sizes
| Outer diameter | Tube | Hollow blocks | Filled blocks |
|---|---|---|---|
| 15 | 5 | 552 | 668 |
| 21 | 5 | 868 | 1,028 |
| 25 | 7 | 1,496 | 2,200 |

Counts come from the same generator as the tool above, so they always match the grid.
How to use it
- Set the outer diameter (the whole width) and the tube thickness (how fat the ring is).
- The tube thickness is also the height, in layers.
- Build layer 1 at the bottom, then press › and build each ring above it.
- The middle layer is the widest ring. The layers above mirror the ones below.
- Hollow keeps only the outer skin of the tube, which saves most of the blocks.
How it works
Each block is placed if its centre falls inside the perfect shape that fits your size exactly. Hollow shapes keep only the blocks within your chosen wall thickness of the outside, so walls never have gaps. Every number on this page is calculated, not typed by hand.
Questions
Why can't the tube be thicker than half the diameter?
At half the diameter the hole in the middle closes completely. Any thicker and the shape is no longer a ring.
Does this work for Minecraft Bedrock and Java?
Yes. Blocks are the same size in Java and Bedrock, so the same layout works in both editions and in every version.
Why is the centre a 2×2 square on even sizes?
An even diameter has no single middle block, so the centre falls between four blocks. Use an odd size (like 25) if you want one middle block to build from.
