Minecraft Sphere Generator
Plan a sphere, dome, circle or ellipse block by block. Set the size, choose hollow or filled and how thick the wall is, then step through the layers from the bottom up. Every layer shows its block count, and you can save it as a PNG or print the whole plan.

Click the plan, then use ↑ ↓ (or ← →) to change layer, Page Up/Page Down to jump 5, Home/End for the bottom and top. Layer 1 is the bottom.
Point at (or tap) a square to see its column, row and distance from the centre.

How to build a sphere in Minecraft
- Pick the shape and size. Type the diameter: the number of blocks across the widest part. Choose hollow for a shell you can live in, or filled for a solid ball.
- Mark the centre. The orange lines show the centre of each layer. Place a marker block at the centre on the ground so every layer lines up.
- Build layer 1, then go up. Copy the purple squares, then press the up arrow for the next layer. The light purple squares show where the layer below was, so you can see where the new layer steps in or out.
- Check your count. Each layer shows its number of blocks; the table and the CSV list them all, with a running total. Totals are also given in stacks of 64, the stack size of most items (Minecraft Wiki, Inventory, checked 27 October 2026).
How the shapes are worked out
- Which blocks are in: a block is part of the shape when its centre is inside the perfect sphere, circle or ellipse of that diameter. This makes every layer symmetrical left to right and front to back, and a sphere's top half mirrors its bottom half.
- Hollow walls: a block is part of the wall when it is within the wall thickness of the outside, counting steps between blocks that share a face. A 1-block wall has no gaps: there is no face-to-face way from the inside out.
- Even and odd sizes: an odd diameter has a single middle block; an even one has two middle blocks, so the centre line falls between them.
- Domes are the top half of a sphere of the same diameter, open at the bottom. With an odd diameter the widest (middle) layer is included.
Circles and ellipses
Circle and ellipse plans are a single layer: use them for round towers, floors, fountains or the base of a dome. An ellipse takes a width and a length, so a 21 × 13 ellipse is 21 blocks across one way and 13 the other. For a round tower, build the hollow circle again on every level.
FAQ
How many blocks are in a Minecraft sphere?
It depends on the diameter and the wall. Enter your size above: the total, the count per layer and the number of stacks of 64 are shown at once. A filled sphere needs far more blocks than a hollow one of the same size.
What diameter should I choose?
Odd diameters (9, 15, 21…) have one middle block, which makes the centre easy to find and mark. Bigger spheres look rounder but take many more blocks.
How do I make a dome?
Press Dome and enter the diameter of the base. The plan shows the top half of a sphere, starting from the widest layer at the bottom.
Can I use the keyboard to change layers?
Yes. Click the plan (or tab to it) and use the up and down arrow keys. Page Up and Page Down jump 5 layers; Home and End go to the bottom and top layer. The layer slider also works with the arrow keys.
Can I print the plan?
Yes. Print all layers puts every layer on paper with its block count; choose "Save as PDF" in the print dialog to keep a PDF. You can also save one layer, or all layers on one image, as a PNG.
Is this an official Minecraft tool?
No. CrispKit is not affiliated with Mojang or Microsoft. The plans work for any block game with a square grid.
