Build Perfect Circles in Minecraft
Generate block-by-block blueprints for circles, ovals, spheres, and domes — with live preview, build order animation, and PNG downloads for Java and Bedrock.
What is a Minecraft circle generator?
A Minecraft circle generator is a free online tool that turns any diameter into a block-by-block pixel blueprint you can copy directly into the game. Pick a size from 5 to 256 blocks, choose a shape, and the generator draws the exact grid - every row, every block - for circles, ovals, spheres, domes and arcs in both Java and Bedrock editions.
The circle generator uses the same discrete-circle math as the midpoint circle algorithm, which is why odd diameters produce a clean, symmetric ring every time. No downloads, no accounts, and the blueprint is always free.
How to use
- 1Choose a shape and a size - odd numbers give a true center block.
- 2Copy the blueprint block by block, or use Builder mode to step through every placement.
- 3Export a PNG, SVG or copy /setblock commands with your world coordinates.
- 4For spheres, domes, toruses and ellipsoids, build one layer at a time from the bottom up.

Frequently asked questions
How do I build a circle in Minecraft?
Pick a diameter, copy the blueprint from the grid, then place the blocks one by one. Start at the center block and work outward for a perfect result every time.
What circle size should I use?
Small circles (5-15 blocks) suit fountains and windows, 21-49 is right for towers and rooms, and anything above 65 is for huge builds like stadiums and coliseums.
Do the blueprints work for Java and Bedrock?
Yes. The grid shows block positions, so it works identically in Java Edition and Bedrock Edition.
How do I build a sphere or dome?
Switch to the sphere or dome tab, then use the Layer slider to see each slice from bottom to top. Build one layer at a time and the shape assembles itself.
Can I copy /setblock commands?
Yes - hit Copy /setblock to get every block as a /setblock command, with your world coordinates applied. Use Copy All layers for spheres, domes, toruses and ellipsoids.
What is Builder mode?
Builder mode turns the blueprint into a step-by-step guide: click blocks to mark them placed, use Next and Prev to move through the build order, or press Play to auto-advance.
