Minecraft Circle Generator
Turn a diameter into a precise block blueprint, then build it row by row without counting every block by hand.

Build the circle, not the spreadsheet.
VoxelCurve converts each row into exact segments, so you can work from the center or from the edge. Your progress stays in this browser and the blueprint can be shared to your phone.

A Minecraft circle generator converts a mathematical circle into a block grid that can be built in a voxel world. Because Minecraft blocks are square, a circle is represented as symmetric horizontal and vertical runs rather than a perfectly smooth curve.
Odd vs. even circle sizes
Odd sizes such as 21×21 have one center block. Even sizes such as 20×20 are centered between four blocks. VoxelCurve keeps this convention consistent across the blueprint, row instructions, material count and export files.
Thin, thick or filled?
Thin creates a one-block outline. Thick expands the wall inward while keeping the same outside dimensions. Filled creates a solid disk, useful for floors and platforms.
Java and Bedrock
The visual blueprint and text instructions work for both Java and Bedrock Edition because they describe block placement rather than game-specific commands. The optional .litematic export is intended for Java Edition workflows using Litematica-compatible tools.
Frequently asked questions
How do I make a perfect circle in Minecraft?
Choose the outside diameter, generate the blueprint, mark the four cardinal edges and then place each row segment symmetrically. The guided builder shows the exact runs so you do not need to count from an image.
Can I make even-sized circles?
Yes. Even circles are centered between the middle four blocks, while odd circles have one center block.
Does the tool work on mobile?
Yes. The blueprint supports touch dragging and pinch zoom, and the Send to Phone button creates a QR code for the current dimensions.
