About MC Circle Generator

A reference for placing blocks

MC Circle Generator turns an outer width and height into a flat block blueprint. It is free to use without an account. The circle tool keeps both axes equal; the oval tool lets you set them separately.

Read a row, mark the blocks you have built, and continue in this browser. Materials, row segments and downloaded PNGs use the same generated grid.

How the outline is chosen

The grid samples cell centers inside an ellipse. Filled keeps every inside cell. Outline keeps an inside cell when at least one neighbor above, below, left or right is outside. This is a four-neighbor boundary; it can differ from a distance-based ring.

The mathematical rule follows the Donat circle generator algorithm reference. Its MIT copyright and permission notice are included in the bundled third-party notice. Site copy, layout and diagrams are created for this tool.
