Minecraft Circle Chart for Survival Builders Survival building is a materials game. Before you mine a single block for a round build, check the chart: it tells you exactly how much stone, wood or concrete the circle will eat, down to the last block, so one trip to the quarry is enough. Block counts (outline / filled): Diameter 9: outline 24 blocks, filled 69 blocks. Diameter 11: outline 28 blocks, filled 97 blocks. Diameter 13: outline 36 blocks, filled 137 blocks. Diameter 15: outline 40 blocks, filled 177 blocks. Diameter 17: outline 48 blocks, filled 225 blocks. Gather one extra stack beyond the number on the chart. You will lose a few blocks to mistakes, scaffolding and the inevitable creeper, and it is better than a second mining trip at midnight. Plan your own circle here: CircleCraftLab
