MOSSBACK STUDIO
Minecraft circle and sphere generator
Pick a size and see exactly which blocks to place. Circles and ovals of any size, and spheres and domes layer by layer, with the number of blocks in every row so you can count along while you build.
Point at a block to see where it is from the centre.
How to build it
- Mark the centre first. The amber lines on the grid run through the middle; with an even size the centre is between two blocks.
- Build one row at a time. The number at the end of each row is how many blocks that row has.
- For a sphere or dome, finish a layer, go one up with the slider, and build the next layer on top of it. The darker blocks show the layer below, so you can line them up.
Thin or thick
- Thin outline: blocks only touch at the corners in the curved parts. Uses the fewest blocks and looks smoothest from far away.
- Thick outline: every block touches the next one by a side, so there are no diagonal gaps. Use it for walls that must keep mobs and water in.
- Filled: every block inside the shape, for floors, pools, and solid spheres.
Sizes that look good
Odd sizes (7, 9, 11, 15, 21...) have a single block in the middle, which is easiest to centre on a point. Small circles below 7 come out quite square in any tool; that is the block grid, not a mistake.
