Domes, towers and mega-builds are easier with friends and a world that is always online. Deploy a Java or Bedrock server in seconds.
How to use the circle generator
Choose a shape, then enter the diameter (and height or depth where it applies). The preview shows one layer at a time as a grid, where green squares are blocks. Use the layer slider to move up through spheres, domes, cylinders and cones. Switch Hollow on for an outline, and raise the thickness for a stronger wall. Copy the layer as text or download it as a PNG to keep next to you while you build.
Common circle sizes
Block counts for a single circle layer. Even diameters have no center block, so odd sizes are easier to measure.
| Diameter | Filled blocks | Outline blocks |
|---|---|---|
| 5 | 21 | 12 |
| 9 | 69 | 24 |
| 11 | 97 | 28 |
| 15 | 177 | 40 |
| 21 | 349 | 56 |
| 31 | 749 | 84 |
Spheres, domes and other shapes
A sphere is a stack of circles that grow and then shrink again, and a dome is the top half of one. The generator also covers ovals, cylinders for towers, cone roofs, arches and spiral staircases. A hollow sphere is much cheaper than a solid one: an 11 block sphere takes 739 blocks solid but only 278 as a shell.
How many blocks will I need?
The total appears under the preview in blocks and stacks of 64. For chests and shulker boxes, send it to the Inventory & Stack Calculator. Planning a huge build with friends? A Minecraft server keeps it online for everyone.

Minecraft Circle Generator FAQ
Can't find what you're looking for?

How do I make a circle in Minecraft?
Pick a diameter in the generator, then build the grid one row at a time. Mark the center block, count out from it using the row widths shown, and fill in each row. Odd diameters have a single center block, which makes them easier to line up.
- ?
What is the best diameter for a Minecraft circle?
Odd diameters such as 11, 21, or 31 are easiest because they have a true center block. Even diameters work too, but their center sits between four blocks, so you need to measure from the middle of the build.
- ?
How do I make a sphere or dome?
Choose Sphere or Dome, set the diameter, and step through the layers with the slider. Each layer is a circle of a different size. Build from layer 1 upward, keeping every circle centered on the same block.

How many blocks do I need?
The total is shown under the preview in blocks and in stacks of 64. Hollow shapes use far fewer blocks than filled ones, so switch Hollow on if you only need the outer shell.

Does it work on Java and Bedrock?
Yes. Circles are just a pattern of blocks, so the same layout works on both editions and in any version.
