Minecraft Circle Generator
Use the circle page when the task is a flat footprint, wall, floor, arena, tower base, or ring measured by diameter or radius. The blueprint updates instantly as you edit values.
- Even footprint: the center is between four blocks, so mark the 2×2 center area before mirroring.

Odd vs Even Center
Has one exact center block. Perfect symmetry around center.
Center is between middle blocks. Mark the shared center line or 2×2 area before mirroring.
Common diameters
Even footprints center between blocks; odd footprints use one center block. Mixed oval footprints use a center line on only one axis.
Circle build workflow
- Choose Diameter for a full footprint or Radius when you already measured from center to edge.
- Pick Outline or Filled before reading the block count.
- Mark the center and the X/Z axes, then follow each row segment.
- Copy the rows or export PNG/SVG/CSV before starting a survival build.
Circle outputs
- Single-layer grid preview with center guide and optional row labels.
- Top-to-bottom Z row segments with X start/end ranges.
- Outline count, filled-count reference, stacks of 64, print sheet, and share link.
Circle mistakes to avoid
- Do not enter radius when the input mode is Diameter.
- For even diameters, mark the 2×2 center area before mirroring rows.
- If you change thickness, recheck both outline and filled material counts.

FAQ
What diameter should I enter?
Enter the full outside width of the circle in blocks unless you intentionally switch to Radius mode.
What does “Blocks if filled” mean?
It is a material reference for the same footprint filled solid, even when the visible blueprint is outline mode.
Should I use PNG or CSV?
Use PNG for a visual reference and CSV when you want exact row ranges in a spreadsheet.
