2D Minecraft shape planner

Minecraft Circle & Oval Generator

Enter a circle diameter or an oval width and height, keep the exact outer size you requested, and get a 2D grid, row plan, counts, PNG, and TXT reference for manual building. The calculation runs locally in your browser and does not produce a 3D or importable file.

Exact outer-size plans for 2D shapes

Enter a diameter for a circle or a width and height for an oval, then choose outline, filled, or inward-thickened mode. The browser creates a 2D grid, row plan, counts, PNG, and TXT reference for manual building.

No account required

Use the plan as a visual reference when you build in Java or Bedrock. It is not an import or compatibility guarantee.

Choose a 2D shape

Circle uses one diameter. Ellipse uses a width and height. Every input is the occupied outer size in blocks.

Inputs

Use whole values from 1 to 256 blocks. Even sizes are valid and keep their center between cells.

Choose a build mode

Outline uses a one-block edge. Thick outline grows inward without changing the outer size. Filled occupies the full shape mask.

Minecraft Circle & Oval Generator FAQ

What does the circle size mean?

Diameter, width, and height mean the final occupied outer dimensions in blocks. A thick outline grows inward, so it does not make the shape wider or taller.

Can I make an even-size Minecraft circle?

Yes. Even sizes stay exactly as entered. Their geometric center falls between cells, while odd sizes have one center cell.

Does this create a sphere, dome, or cylinder?

No. This tool is only for 2D circles and ovals. It does not create spheres, domes, cylinders, 3D previews, or game data files.

What can I do with the PNG and TXT files?

Use them as a manual row-by-row build reference. They are not a Minecraft world, schematic, litematic, NBT file, or automatic game import.
