Minecraft Pixel Circle Generator
Block-by-block circles and ellipses you can copy straight into Minecraft, with the block count and a tick-off chart for the build.
- 2 – 400 blocks wide
- Outline or filled
- Block counts
Type a diameter and get a block-by-block circle you can copy straight into Minecraft. The generator uses the same rule builders use by hand: a block is placed when its centre falls inside the circle, so every size comes out as round as the grid allows. Set width and height separately for ellipses, choose an outline or a filled shape, pick the ring thickness, and read the block count before you start gathering materials.
How to build a circle from the chart
- Set the diameter in blocks. Leave "Perfect circle" ticked for a true circle, or untick it and set width and height separately for an oval.
- Choose Outline or Filled, then set the ring thickness. Tick "No diagonal gaps" if you need to walk around the ring or keep water inside it.
- Check the block count and stacks so you gather enough material before you start.
- Mark the centre in your world, then build one quarter of the ring from the chart and mirror it to the other three quarters. Zoom in on the preview to count runs of blocks along each row.
- Click each block on the preview as you place it - it turns green and the "Placed" counter climbs. Progress is remembered in your browser, so you can come back mid-build.
- Download the PNG if you want the chart open on a second screen or phone while you build.
Odd or even diameter?
An odd diameter has a single centre block, so the circle is symmetrical around a block. That is the right choice when the circle wraps around something: a beacon, a fountain, a central pillar, a tree.
An even diameter is centred on the line between two blocks. Use it when something two blocks wide has to pass through the middle, such as a doorway, a path or a rail line, or when the circle must line up with an even-sized build like a 16×16 chunk.
Thin, thick or filled
A one-block outline uses the fewest blocks (24 for a 9-block circle, 40 for 15) and works for walls, tower edges and decorative rings, but its blocks only meet at the corners on the diagonals. If you need to walk the ring, hold water or keep mobs out, tick "No diagonal gaps" or set the thickness to two or three. Filled gives you a solid disc for floors, ceilings, pool bottoms and the base layer of a dome.
Very small circles look like octagons because there are not enough blocks to show the curve. Below about nine blocks that is simply what a circle is in Minecraft; from around fifteen upwards the shape reads clearly as round.
Pixel circle FAQ
How many blocks does a 15-block circle need?
A 15-block circle is 40 blocks as a one-block outline and 177 blocks filled in. A 31-block ring is 84 blocks. Set the size above and the block count, plus how many stacks of 64 that is, updates instantly.
How do I make a perfect circle in Minecraft?
There are no true circles on a block grid, only the closest approximation. This generator fills a block whenever the centre of that block falls inside the circle, which gives the roundest result the grid allows for any diameter. Keep "Perfect circle" ticked so width and height stay equal, then build the ring row by row.
Should I pick an odd or even diameter?
Odd diameters (15, 21, 31) have a single centre block and a true middle row, so they sit symmetrically around a beacon, fountain or pillar. Even diameters centre on the line between two blocks, which is what you want when a doorway, path or two-block-wide feature runs through the middle.
What is the difference between a thin outline and a walkable ring?
A thin outline uses the fewest blocks, but its corners only touch diagonally, so you cannot walk around it and water or mobs can slip through. Tick "No diagonal gaps" to make every step orthogonal, or raise the thickness to two or three blocks for a proper walkway.
Can I use this for domes and spheres?
A dome is a stack of circles that shrink layer by layer. Use the Sphere Generator for the full layer-by-layer plan; this tool is for a single flat circle or ellipse, like a tower footprint, a pool or a round floor.
