Start from the widest layer
The widest slice gives you the footprint fastest. Once that ring feels right, moving up or down becomes much easier.
Minecraft Sphere Generator
Plan solid spheres, hollow shells, domes, and circles before you place blocks in the world. Step through each layer, compare the silhouette from the top and the front, and copy the current slice as a clean build reference.

Copy & text plan
Copy the current layer while you build. Copy every layer when you want a full reference for yourself or another builder.
Top view
Front view
The silhouettes answer the practical questions first: how wide the build will read from above, and whether the curve still feels clean from the front.
How to use the planner
Use circles for flat foundations
The circle modes are useful on their own for floors, towers, wells, ritual zones, and any top-down round composition.
Build hollow when the inside matters
If the outside silhouette is the goal, a hollow shell usually saves blocks and gives you room for lighting, stairs, and decoration.
How to use the generator
Pick a mode and radius, then step through the shape layer by layer. The summary, the 3D preview and the block map all follow the layer you select.
Six modes
Solid sphere, hollow sphere, upper and lower dome, filled and outline circle. Hollow modes add a shell thickness from one to four blocks.
Radius and diameter
Every shape is centred on one block, so the diameter is twice the radius plus one: radius 7 is 15 blocks across. Radius goes up to 64.
Layers
Previous, Next, the slider and the layer list move through the slices; each is labelled with its height from the centre, y=0 being the middle and widest layer. The 3D view can show the whole shape, highlight the layer, or show that layer alone.
Copy
Copy current layer while you build; copy all layers for a full reference to share. In the copied text # is a block and . is empty.
Planning a big build
Count the material
Total blocks divided by 64 is the number of stacks; a shulker box holds 27 stacks, 1,728 blocks. A hollow shell needs far fewer blocks than a solid sphere of the same radius.
Build from the widest layer out
Start at the middle layer, the widest one, and work up and down from it. It is easier to keep the curve true than starting at a tiny cap.
Top and front views
The top view shows the current layer as you will place it; the front view shows the silhouette, which is where an uneven sphere shows first.
Any version
Spheres are block positions only, so the plans work in every edition and version. For flat circles, rings, arches and dome profiles without the full 3D shell, the circle & dome planner is lighter.
