Each chart is one circle drawn with the block-center rule. Quarter lists the block count of every row in the top-right quarter, from the top row to the middle; 2×3 means three rows of 2.

Everything is drawn in your browser. Nothing you enter is uploaded or saved, and your placed marks disappear when you close the page. This is an unofficial fan tool: it is not made by or connected to Mojang or Microsoft.

How to read the chart

Every card is one circle drawn with the block-center rule. Under it you see the number of blocks and the quarter pattern: the number of blocks in each row of the top-right quarter, from the top row to the middle. A pattern such as 5 · 3 · 2 · 1×3 means a row of 5, then 3, then 2, then three rows of 1.

Build one quarter from the pattern and mirror it three times to finish the circle. The table at the bottom lists the thin, thick and filled block counts for each diameter so you can plan materials.

  • Thin keeps a one-block outline; thick closes corner joins.
  • Odd diameters have a single center block, even ones a 2×2 center.
  • Pick another range to see sizes up to 100.

Why other charts may differ

Other charts may round the edge differently, so a circle of the same width can differ by a block or two. This one always keeps a block when its center is inside the ideal circle.

Common questions

Which circle sizes does the chart include?

Every diameter from 5 to 32 by default. Use the Sizes menu for 3 to 16, 17 to 32 or larger ranges up to 100.

What is the quarter pattern?

It lists how many blocks the top-right quarter has in each row, from the top row down to the middle row. Repeat marks such as 1×3 mean three rows of that length.
