How to Make a Circle in Minecraft

Minecraft is built entirely from square blocks — so a "circle" is actually a staircase approximation of a circle. The algorithm picks the blocks whose centres are closest to the ideal mathematical circle.

Here's how to use this generator to build a perfect Minecraft circle:

1. Set your desired diameter with the slider.
2. Adjust thickness for a hollow ring (1 block = outline only) or a filled circle (set to half the diameter).
3. Pick a block color that matches your build material.
4. Download the PNG and use it as a reference while building in-game.
5. Build layer by layer — the template shows exactly which blocks to place.

Tips for large circles

For circles larger than 50 blocks across, use the quadrant axis option to divide the circle into 4 symmetric sections — you only need to follow one quarter and mirror it.

How the Algorithm Works

The generator uses the midpoint circle algorithm — the same technique used in computer graphics since the 1980s. For each x-position, it calculates the y-coordinate on the circle's edge using the equation:

Because Minecraft blocks are discrete units, we round each y-value to the nearest integer. The result is the most accurate circle possible at any given diameter — no command blocks or mods required.
