Minecraft Circle Chart: Every Circle from 3 to 40 Blocks

How to use it

1. Find the width you want in the chart. The number above each circle is the diameter in blocks.
2. Pick Thin, Thick or Filled. The drawings and counts change at once.
3. Open a circle in the generator for a row by row guide and a PNG, or press Print chart.
4. Build one quarter, check it against the drawing, then mirror it for the other three.

How to read the circle chart

Every drawing is one circle seen from above. One square is one block. The number on top is the diameter, the full width of the circle in blocks, and the number below is how many blocks the circle needs in the style you picked. Click any circle to open it in the circle generator, which lists every row as "skip so many, place so many".

All 38 circles use the same rule. A block is placed when the centre of its square lies inside a perfect circle of that width. The thin outline keeps only the blocks that touch the outside along a side. The thick outline keeps every block that touches the outside, corners included, so it has no diagonal gaps. The filled disc keeps everything.

Block counts for every size

This table repeats the counts from the chart with all three styles side by side, so you can compare before you mine. Stacks are counted at 64 blocks.

Two patterns stand out. The thick outline is always 4 blocks less than four times the diameter: 76 for a 20 block circle, 156 for a 40 block circle. The thin outline is close to 2.8 times the diameter. The filled disc grows with the square of the size, which is why a 40 block floor needs four times the blocks of a 20 block floor.

Bigger circles

Past 40 blocks a picture is hard to count by eye, so use the generator and follow the rows. For planning, these are the totals for a few large sizes people often build: arenas, castle towers and map-sized rings.

Which size to pick

Odd sizes have one block in the middle. That is what you want for a tower around a single column, a beacon, or a spiral staircase with a centre post. Even sizes have a two by two middle, which suits a double door or a 2 by 2 tree trunk in the centre.

Small circles, up to about 7 blocks, look more like rounded squares. That is not a mistake in the chart, there are simply too few blocks to show a curve. Between 9 and 15 blocks the shape starts to read as round, which is why so many towers use 11, 13 or 15. For a large dome or arena, anything from 25 up looks smooth from a distance.

A 16 block circle fits exactly inside one chunk. A 32 block circle spans exactly two. That helps when you want a build to line up with chunk borders, for example to keep a farm loaded.

Building from the chart

1. Choose the centre and mark the four outer points: top, bottom, left and right. For a 15 block circle they are 7 blocks from the centre block.
2. Build the top left quarter by copying the drawing row by row.
3. Mirror that quarter to the right, then mirror the whole top half down.
4. Walk around the finished ring and compare each side with the chart. A single wrong step is easy to see when the four quarters do not match.

For a wall, stack the same outline layer on layer. Ten layers of a thin 20 block circle is 560 blocks, 8 stacks and 48. To turn a total into chests and shulker boxes, use the stack calculator. For round shapes in three dimensions, the sphere, dome and cylinder generators draw every layer.

Chart or generator?

A chart is fastest when you already know the width and want to see the shape. The generator is better for odd jobs: ovals, circles over 40 blocks, a row list you can tick off, or a PNG of one circle at a large size. Both use the same maths, so a 23 block circle in the chart is the same as a 23 block circle in the generator. The pixel circle generator does the same for pixel art and cross-stitch, without the game terms.
