Generate a pixel-perfect Minecraft circle of any diameter, with a block grid preview and counts.
Odd diameters have a single centre block; even diameters have a 2×2 centre. The grid preview below shows filled blocks in orange.
Filled counts every block inside the circle; outline counts only the ring blocks you actually place for a hollow circle. For a dome or sphere, build the same circle at each height with a shrinking diameter.

How to use this tool
Type the circle's width in blocks, for example 11.
Orange squares are blocks to place; pale squares are empty. Build row by row.
Use the filled count for a solid disc and the outline count for a hollow ring.
For bigger circles, place the centre first, then work outward row by row.
Formula & worked example
Diameter 5: the grid has 21 filled blocks and a 12-block ring (rows: 3, 5, 5, 5, 3 blocks). Diameter 11 gives 97 filled blocks.
Limitations — read this before you rely on it
Pixel circles are approximations: a block is either in or out, so small circles look chunky and even diameters have no single centre block. The counts here use centre-distance, the standard method for Minecraft circle generators.
Frequently asked questions
Pick a diameter, then place blocks row by row following a pixel grid — this generator draws that grid and counts the blocks for you.
97 blocks filled, or 32 blocks for just the ring.
Odd diameters have one centre block and look symmetrical around it; even diameters have a 2×2 centre and suit builds centred on a 2×2 feature.
Yes: stack circles with shrinking diameters as you go up, mirroring them below the middle for a full sphere.
Very small diameters (under about 7) have too few blocks to look round. Use a larger diameter for a smoother curve.
