About Minecraft Shape Generator
Building perfect geometric shapes in Minecraft is tricky by hand. This tool calculates the exact block coordinates for circles, spheres, pyramids, cylinders, domes, rings, squares, and diamonds — all driven by mathematical formulas.
Select a shape, adjust the size (radius or edge length), toggle hollow mode for shells instead of solid fills, and choose a block type as a reference label in the exported file. The live grid preview shows a top-down view of each horizontal layer. Use the layer buttons to flip through multi-level shapes like spheres and pyramids.
Copy the coordinates to clipboard or download a .txt file listing every (x, z) position per layer — ready to follow while building in-game. All computation runs entirely in your browser.

Frequently asked questions
What shapes can the tool generate?
Circles, ovals, spheres, cylinders, pyramids, domes, rings, squares, and diamonds. Select the shape type from the dropdown and set the dimensions — the tool calculates exact block coordinates instantly.
How do I use the coordinates in-game?
Copy the output or download the .txt file. The coordinates are relative, so pick a starting point in your world, then place blocks according to each (x, z) position listed. For 3D shapes, step through each layer one at a time from bottom to top.
What does hollow mode do?
Hollow mode outputs only the outer shell of the shape rather than a solid fill. This is useful for large builds — a hollow sphere at radius 30 requires far fewer blocks than a solid one and is much more practical to build in survival.
What is the maximum radius I can generate?
The tool supports radii up to 500 blocks, which covers even the largest survival megabuilds. For very large radii, exporting the coordinates to a .txt file is recommended so you can refer to them section by section.
What is a 'layer' in the shape output?
For 3D shapes like spheres, pyramids, and cylinders the output is split into horizontal layers (Y levels). Each layer shows the top-down block pattern for that height. Use the layer navigation buttons to step through each slice and build from the bottom upward.
