About this calculator
Draw a flat circular block layer as a grid pattern. The generator does not create a dome or stacked vertical shape.

Frequently asked questions
Does this make a sphere or dome?
No. It creates one flat, centered pixel-art disk pattern and reports its width and block count. It does not calculate vertical layers, a dome, or a sphere.
Which inputs and limits apply to Minecraft Circle Generator?
Use the units shown beside each field. These are form limits, not recommended settings. Diameter in blocks (odd numbers look best): 3–41 on(x, y): r − 0.9 ≤ √((x − r)² + (y − r)²) ≤ r + 0.5 Generates one flat, symmetric pixel-art disk pattern; it does not calculate a dome or vertical layers.

What is a complete worked example for Diameter in blocks (odd numbers look best) = 15; Style = Hollow outline?
Inputs: Diameter in blocks (odd numbers look best) = 15; Style = Hollow outline. Calculation: on(x, y): r − 0.9 ≤ √((x − r)² + (y − r)²) ≤ r + 0.5. Results: Block pattern = .....#####..... ...###...###... ..##.......##.. .##.........##. .#...........#. ##...........## #.............# #.............# #.............# ##...........## .#...........#. .##.........##. ..##.......##.. ...###...###... .....#####.....; Width in blocks = 15; Height in blocks = 15; Blocks needed for one layer = 56.
