21 blocks - unique pattern
Layers count upward from the bottom of the shape. A dome starts at the upper center plane. Repeated patterns are computed once and labeled so mirrored sphere layers can reuse the same block map.
Stack estimates assume the selected blocks stack to 64. Shulker estimates assume 27 stacks, or 1,728 blocks, per box; confirm the actual block stack size before gathering materials.

How to Use the Minecraft Sphere Generator
- Enter a whole-number diameter from 3 to 51 blocks.
- Choose a full sphere or an upper dome, then choose a hollow shell or solid fill.
- For a hollow build, set the wall thickness and select Generate sphere plan.
- Move through the horizontal layers from bottom to top and reuse any layer labeled as a repeated pattern.
- Mark finished layers, copy the current grid, or download and print the complete text plan.
How Minecraft Sphere Layers Are Generated
Every candidate block is represented by its center point on a three-dimensional square grid. The generator measures that center from the shape center and includes it when the distance is at or inside half the selected diameter. Hollow mode removes centers at or inside the inner radius, which is the outer radius minus the selected wall thickness.
A full sphere includes every horizontal layer. An upper dome starts at the upper center plane and keeps the layers above it. Odd diameters center on one block; even diameters center between blocks. The plan hashes each two-dimensional layer pattern so matching and mirrored layers are labeled for reuse instead of asking you to recount them.
Minecraft Sphere and Dome Examples
15-block hollow sphere
With diameter 15, Full sphere, Hollow shell, and a one-block wall, the plan uses 602 blocks across 15 layers. The layer comparison reduces those layers to 7 distinct block patterns.
15-block upper dome
The same 15-block hollow settings in Upper dome mode keep 8 layers from the center plane to the top and use 321 blocks. The base layer is included, so the dome has a complete widest starting ring.
15-block solid sphere
Changing the 15-block sphere to Solid fills the interior and raises the deterministic total to 1,791 blocks. That is 27 complete stacks of 64 plus 63 blocks.
Material Counts, Layer Order, and Limits
Layer numbers count upward from the bottom of the selected shape. Stack totals assume blocks that stack to 64. The shulker estimate assumes 27 stacks, or 1,728 blocks, per box. Some blocks use smaller stack sizes, and survival builds also need scaffolding, lighting, entrances, framing, or replacement blocks that are not part of the sphere itself.
This is a deterministic block-center approximation, not a promise of a mathematically smooth surface or an in-game schematic. Copy and download produce text blueprints only. TheToolSite is independent of Mojang and Microsoft; Minecraft names describe the planning workflow, and no game assets or data files are included.
