Minecraft Circle Diameter Reference Chart
Use this table to plan circular structures. All values are calculated using MCCircleGrid's deterministic voxel rasterization engine.

How to Read This Table
The Octant Sequence shows the consecutive linear runs of blocks from the cardinal apex to the 45-degree diagonal. Start at the top cardinal point, lay the first run, then step diagonally and place the next run, continuing until you reach the diagonal corner. Mirror this sequence across all four quadrants to complete the circle.
