About Circle Generator

What this site does

Circle Generator is a free set of planners for Minecraft builders. Enter a size and the tool draws the block grid, lists the length of every row and counts the blocks and stacks. The main tool is the circle generator; the other pages cover ovals, spheres, domes, round towers, spiral staircases, arches, cones, hexagons and octagons, pixel art and beacon pyramids, with a stack calculator for turning counts into stacks.

How the grids are calculated

Every shape follows the same plain geometry. The grid is D blocks across, and each cell is judged by its centre: a cell is in the shape when its centre is within half the diameter of the centre of the grid, and a cell exactly on that distance is included. The check uses whole-number arithmetic, so the same input always gives the same grid. There are no empirical constants or hand-tuned tables behind any result.

A block grid can only approximate a curve, so each result is the nearest set of whole blocks under the stated rule rather than a perfect round shape. Each tool page states its own rule, with small examples you can check by hand.

Sources and data

The grids are computed in your browser from the rules above; no third-party dataset is used. Stack sizes and chest sizes are described with reference to the Minecraft Wiki.
