Minecraft Circle Generator

How to use the circle generator

1. Set the size. Enter the width in blocks. Width and height stay linked for a circle; tap the lock to unlink them for an oval.
2. Pick a wall style. Thin uses the fewest blocks, thick closes every diagonal gap, and filled gives a solid disc.
3. Find your center. Stand on the block you want in the middle and note its X and Z. Enter them under world coordinates to get the exact position of every block.
4. Build and track. Switch to Track build and tap blocks as you place them. The green blocks and the progress bar show what is left, and your progress is saved in this browser.

Thin, thick or filled: which style to pick

Thin is the classic pixel circle. It looks clean from above and costs the fewest blocks, but where the curve steps diagonally, two blocks meet only at a corner. Water can leak through those spots and small mobs can sometimes squeeze past fences built on them.

Thick adds one block at each of those corners, so the ring is sealed all the way round. Choose it for castle walls, pens, moats and anything that must hold water. Raise the wall thickness to make a ring several blocks deep.

Filled covers the whole area. Use it for round floors, platforms, ponds, or as the layer-by-layer base of a dome or tower roof.

Odd or even diameter?

With an odd width such as 21, the circle has one center block, highlighted in the preview as a light band through the middle row and column. Doors, paths and pillars can sit exactly in the middle, so most builders prefer odd sizes.

With an even width such as 20, the center falls between four blocks, shown in the preview as a colored line. Even circles can look a little rounder at small sizes, but nothing can sit perfectly centerd on them.

Building ovals and ellipses

An oval is simply a circle with a different width and height. Unlink the size fields, enter both numbers and the generator draws the ellipse that fits that box exactly. Long ovals suit arenas, ship hulls, racetracks and garden beds. All styles, the tracker, coordinates and printing work for ovals too.

Tips for big circles in survival

• Build the four points where the circle crosses the center lines first. They are always straight runs and give you anchors to check against.
• Work one quarter at a time. The quarter pattern above lists how many blocks each row needs, from the top of the circle down to the middle row.
• Use a cheap placeholder block such as dirt for the first ring, then replace it with your final material once the shape looks right.
• For circles wider than about 60 blocks, print the plan. The printout splits large circles across several pages with bold lines every 10 blocks.
• Turn on Track build so you can stop and come back later without counting again.
