How are the blocks calculated?

The tool builds a symmetric circle or ellipse and counts its blocks. Filled mode keeps the interior, while outline mode removes inner layers.

Are my settings and progress saved?

Settings and progress are saved in the browser when storage is available. Clearing browser data removes them, but shared links include settings, not progress.

What is the difference between odd and even diameter circles?

Odd diameters have a single centre block, while even diameters have a centre that falls between four blocks. This affects how the circle is positioned and built.

Can I use this tool to automatically build in my Minecraft world?

No, this tool creates a 2D plan that you must follow manually. The site does not edit a game world or place blocks automatically.

About Minecraft Circle Generator

Screenshot of the Minecraft Circle Generator homepage — The Minecraft Circle Generator homepage

Minecraft Circle Generator is an independent block-pattern planner that helps players lay out circular and elliptical structures before building them in the game. The tool turns dimensions into a grid that can be followed one row or layer at a time, offering three main planners: Circle & Ellipse Generator for top-view outlines and filled footprints, Sphere Generator for three-dimensional forms as horizontal layers, and Circular Tower Planner combining a filled foundation, repeated wall rings and optional dome.

The generator creates pixel-perfect patterns on a square block grid, calculating block counts and material stacks needed. Players can choose filled or outline styles, adjust thickness, and follow step-by-step build mode marking completed rows. The tool provides multiple export options including PNG, SVG and CSV formats, allows printing blueprints, and enables copying coordinates and text grids for in-game reference.

No account is required to use the tool. Settings and progress are saved in the browser when storage is available. The site does not edit a game world or place blocks automatically; players must follow the generated plan when building.
