Step-by-step guide

How to use the Circle Generator

Enter the outside diameter of the circle in blocks.
Read the generated grid from one row to the next, preserving symmetry.
Use the block total to collect materials before starting the build.

Calculation

Formula and game rule

The grid marks cells whose centre lies inside the chosen radius but outside the radius minus one block, producing a one-block outline.

Worked example

Example result

For a diameter of 15, copy one quadrant first and mirror it across both centre lines to reduce placement mistakes.

What to check before using the result

Even and odd diameters have different centres, so do not add or remove a centre row after generation.
Large circles look smoother but still follow a square block grid rather than a mathematically continuous curve.

Java and Bedrock Edition

Block geometry is the same in Java and Bedrock Edition; the chart works for either edition and any block type.
