Minecraft circle generator

Plan circles, ovals, spheres and domes block by block – with block counts, layer by layer, and ticks for the blocks you have already placed.

Thick: the edge is closed even at the corners (watertight). Thin: fewer blocks, some only touch at a corner.

How to plan a circle in Minecraft

  1. Pick the shape: circle (or oval), sphere or dome.
  2. Enter the diameter – how many blocks the shape measures at its widest point.
  3. Pick the fill: filled, thick edge or thin edge.
  4. Build it row by row. Hover over the grid to see how many blocks a row has.

Odd or even diameter?

An odd diameter such as 25 gives the shape a centre block – perfect for a tower, a fountain or a beacon in the middle. With an even diameter such as 24 the centre lies between four blocks, which suits gates and corridors two blocks wide. The red line always marks the centre.

Thick or thin edge?

With a thin edge some blocks only touch at a corner. That saves blocks and looks clean from above, but water and small mobs can slip through. A thick edge closes those gaps – use it for walls, pools and glass domes.

Spheres and domes layer by layer

For spheres and domes the generator shows one layer after another, from the bottom up. The layer below shows through faintly, so you can see where the edge steps in or out. “Blocks in total” helps you gather materials: one stack is 64 blocks.

Frequently asked questions

How many blocks do I need?

Right above the grid: the blocks for the whole shape and the same number in stacks of 64. For spheres and domes you also see the blocks of the layer shown.

Can I save my progress?

Yes. Click a block to tick it as placed, drag to tick several. The ticks stay in your browser only, for your last 12 shapes up to 256 × 256 blocks.

How big can a shape be?

Circles and ovals up to 1,000 blocks, spheres and domes up to 400 blocks across.

Does it work for Java and Bedrock?

Yes. The generator only counts blocks, and circles and spheres are the same in both editions.

How do I take the plan with me?

“Save picture” downloads the grid as a PNG, for example for your phone next to the PC. “Copy link” shares exactly this shape with all settings.
