How to use the circle generator
- Set the diameter. Type a width or use the plus and minus buttons. Keep "Keep it a circle" ticked for a round shape, or untick it to make an oval.
- Choose a style. Thin uses the fewest blocks, Thick makes a solid wall with no diagonal gaps, Filled gives you a disc for floors, and Wall width lets you set any thickness, such as a 3 block thick tower wall.
- Build from the centre lines. The red dashed lines mark the middle. Count blocks out from them, and mirror every row left to right and top to bottom.
- Tick blocks off. Tap any block to turn it gold as you place it. The counter shows how many you have marked.
- Save it. Download a PNG, print it, or copy the link: the link keeps your exact size and style, so you can open the same plan on your phone next to the game.
Every tool for round builds
How the circle is worked out
Each block on the grid is tested at its centre point. If that point falls inside the circle (or oval) of the size you chose, the block is part of the filled shape. The outline is then taken from the edge of that filled shape: a block stays if it touches the outside along a side (thin) or along a side or a corner (thick). Wall width keeps every block that is within that many steps of the outside. Because the test is the same for every block, the result is exactly symmetrical in both directions.
Block counts for common circle sizes
These come from the same rules as the generator above.
| Diameter | Thin outline blocks | Filled blocks |
|---|---|---|
| 5 | 12 | 21 |
| 7 | 16 | 37 |
| 9 | 24 | 69 |
| 11 | 28 | 97 |
| 15 | 40 | 177 |
| 21 | 56 | 349 |
| 25 | 68 | 489 |
| 31 | 84 | 749 |
| 41 | 112 | 1313 |
| 51 | 144 | 2053 |
| 64 | 180 | 3228 |
| 101 | 284 | 8021 |
Tips for building big circles
- Mark the centre block first with a different block, then build the four points straight up, down, left and right of it. Every other row fits between those 4 points.
- Build one quarter, then copy it. The quarter pattern under the grid lists how many blocks each row adds, from the top row to the middle.
- For towers, use the same circle on every layer, or open the sphere generator to make each layer a little smaller for a round roof.
- For a curved wall around a base, use Wall width set to 2 or 3 so the wall is easy to walk on.
Questions
How do I make a circle in Minecraft?
Pick a diameter above, then copy the green blocks onto the ground one row at a time. Start with the top row, count blocks from the dashed centre line, and mirror each row on the other side. Tap blocks as you place them so you never lose your place.
Should I use an odd or even diameter?
Odd diameters (like 21 or 31) have a single centre block, which makes it easy to line the circle up with a door, a beacon or a tower in the middle. Even diameters (like 20 or 32) have a 2 by 2 centre and look slightly smoother at small sizes. Both are correct circles.
What is the difference between thin and thick?
A thin circle connects its blocks corner to corner, so it uses the fewest blocks but has diagonal gaps you can walk through. A thick circle fills those corners so every block touches the next by a full side, which makes a solid wall with no gaps for mobs or water.
How many blocks do I need?
The numbers above the grid show the exact block count for the shape on screen, and the same count in stacks of 64. A thin 21 block circle needs 56 blocks; a filled one needs 349.
Can I make a circle bigger than 512 blocks?
The grid goes up to 512 by 512. For bigger builds, use the quarter pattern below the grid: it lists the run lengths for one quarter of the circle, which you repeat and mirror around the centre.
Does this work for Bedrock, Java and other block games?
Yes. A block circle is just a grid, so the plan works the same in Minecraft Java, Bedrock, Pocket Edition, and other block games, and for pixel art, cross stitch or knitting charts too.
