How to Use This Tool
Building perfect circles in a voxel game like Minecraft can be tricky. This generator mathematically calculates the absolute best block placement for any radius.
- Select whether you want a perfect Circle or a custom Ellipse (Oval).
- Enter the total block width (diameter) you need for your build. Odd numbers (e.g., 31) have a single center block, while even numbers (e.g., 30) have a 2x2 center.
- Choose your rendering style depending on if you are building an outline, a thick wall, or a solid platform.
- Click the Export Image button to save the blueprint to your computer so you can reference it while playing.
Frequently Asked Questions
Why do the circles sometimes look slightly blocky?
Because Minecraft forces players to build on a grid, true curves are impossible. This tool uses Bresenham's Midpoint algorithm to generate the mathematically closest approximation of a curve on a grid.
What happens if I use an even number for the width?
When you use an even number, there is no true single center block. The generator will create a shape with a 2x2 (4 block) perfectly centered core.
Can I build spheres with this?
To build a sphere, generate a circle for the equator (widest point). Then, work your way up layer by layer, generating progressively smaller circles. We plan to add a dedicated 3D sphere generator in the future.
