64 block circle in Minecraft

How to use it

1. Check the grid and the block count in the tool.
2. Open the row by row guide and start at the top row.
3. Place each row as written: skip the gap, then place the run. Only the top 32 rows are listed, the rest is a mirror image.
4. Download the PNG if you want to keep it open next to the game.

The 64 block circle in numbers

Sixty four blocks is the width of a stack, which makes counting easy. It suits a round lake, a crater or the outer ring of a big spawn build.

The outline of a circle 64 blocks wide is made of 180 blocks. That is 6 per cent of the 3,228 blocks in the full disc, so a ring is far cheaper than a floor. The ideal area of a circle with this diameter is about 3,217 square blocks, and the filled version differs from that by 0.3 per cent. The circumference of the ideal circle is about 201.1, for comparison.

Row by row guide for the top half

Start at the top row. Each line says how many empty blocks to leave from the left edge and how many to place. When a line has two runs, leave the gap between them empty. Rows below the middle repeat the same lines in reverse order.

1. skip 26, place 12
2. skip 22, place 4, skip 12, place 4
3. skip 20, place 2, skip 20, place 2

The filled disc has rows of these widths from the top: 12, 20, 24, 30, 32, 36, 38, 42, 44, 46, 48, 50, 50, 52, 54, 54, 56, 58, 58, 58, 60, 60, 62, 62, 62, 62, 64, 64, 64, 64, 64, 64. Mirror them for the lower half.

Symmetry and straight edges

The diameter is even, so there is no centre block. The middle is a two by two square, and the circle has two middle rows and two middle columns. Mark the two centre lines before you start. The longest straight run is 12 blocks. Long flat runs make a circle look squarer, and short ones make it look rounder, which is why sizes like 50 and 100 look a little different from 64 even though they are close.

Block counts for walls of different heights

A round tower or wall repeats the thin outline layer after layer. These are the totals for a 64 block wide wall.

Building it without mistakes

Place four marker blocks, one at each side, then fill in the runs between them. The two middle blocks on each side are the ones that line up with the centre lines. Build one quarter, check it against the guide, and copy it to the other three by mirroring. Count your first row before you build the rest, a single wrong skip shifts the whole curve.

For a roof or a floor, switch the tool to Filled. For a wall with no diagonal gaps, which matters for moats, pens and sealed rooms, switch to Thick and expect 72 extra blocks per layer.

For ovals or any size not listed, use the circle generator. To turn a circle into a ball, try the sphere generator, or the stack calculator to turn a block total into chests.
