Minecraft circle and oval generator

Set the width and depth and get a circle or oval out of blocks: a thin outline, a ring of any thickness or a solid fill. The base for towers, pools, fountains and round plazas. The shape shows up in 3D at once, each layer sits on a grid, export to .litematic and .schem.

How it works

1. Set the dimensions with the sliders — the shape is recalculated instantly and shown in 3D.
2. Pick a block (some tools take two: main and secondary).
3. Turn on Layers to see the shape slice by slice — handy for building by hand.
4. Download .litematic for Litematica or .schem for WorldEdit.

Examples

• Circle 31
• Oval 41×21
• Filled plaza 15

FAQ

How do I make a clean block circle?

Use the same width and depth: an odd size gives a circle with a centre block, an even size puts the centre between blocks. Thickness 1 is an outline for walls; Filled gives a floor or plaza.

How do I build this without mods?

Open the schematic in the viewer, turn on Layers and place blocks layer by layer on the grid. With Litematica or WorldEdit the schematic is pasted in one go.

Why does the shape look stepped?

Blocks are whole, so every curve turns into steps — the game does the same. An odd size gives a clean centre block, an even size gives two.

Is it free, no sign-up?

Yes. Everything is computed in the browser; the file is built locally and never uploaded.
