Minecraft Sphere Generator review
A free browser tool for planning round builds with layer views and a rotatable 3D preview.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Minecraft Sphere Generator is a browser-based tool for planning round Minecraft builds. It suits solo builders who want to inspect spheres or ellipsoids before placing blocks, including users planning a dome by building half a sphere. You can set a diameter or separate ellipsoid dimensions, then choose whether the shape is hollow or filled. The tool is part of Minecraft Code List, an unofficial Minecraft reference site.
Its strongest planning aid is the combination of layered and 3D views. A slider steps through horizontal 2D layers from bottom to top, while the rotatable 3D preview gives a view of the full form. Total and per-layer block counts help estimate the materials needed at each stage. Layer patterns can also be copied as text, which offers a practical way to reference a build while working, although the page does not specify file export formats.
The focus is deliberately narrow: sphere and ellipsoid generation rather than a broad library of Minecraft shapes. Coordinate output is not part of the tool, so builders who need coordinates or a wider range of structure types should look elsewhere. The tool is available on the site without a stated charge. Pick it for visualizing round builds, checking layer-by-layer counts, and adapting a sphere into a dome; skip it if your planning depends on coordinates or file-based export.

- Where it doesn't
- Shape generation is limited to spheres and ellipsoids.
- It does not provide coordinate output.
- The page does not specify export formats or a maximum dimension.
