A free browser-based pixel circle chart for Minecraft. Type a diameter, get the exact block outline to build in-game, plus the material count. Works for towers, arenas, walls, nether portals, and dome slices.

How to use this Minecraft circle generator

Type the diameter you want (or set independent width and height for an ellipse), then read the grid. Every red block is a block you place in Minecraft; the grey inside is the empty interior. The Details box on the right tells you how many blocks you need, how many stacks that is, and the final diameter.

The generator uses a midpoint ellipse rasterizer - the same technique the classic Plotz builder uses - so it produces the recognised symmetric ring pattern rather than any interpretation of a circle. Adjust the Scale slider to zoom the on-screen chart up or down without changing the underlying block count.

Great for round Minecraft builds

Use the tool to plan castle turrets, wizard towers, nether portal frames (17x21 is the vanilla portal), arena walls, cake bases, water fountains, redstone clocks, farm rings, and world-border markers. Save the chart as a PNG to print on paper, or SVG if you want to open it in Figma or Illustrator to layer over blueprints.

Frequently asked questions

How do I use the Minecraft circle generator?
Enter the diameter (in blocks) you want your circle to be. The generator uses an ellipse rasterizer to figure out which blocks form a clean circular outline at that size, then draws them on the grid. Toggle Force circle off to draw ellipses (different width and height). Click PNG or SVG to download the chart as a printable reference.

What size circle should I build in Minecraft?
For most round builds pick an odd diameter (7, 9, 11, 15, 21) - they look more symmetrical in-game because they have a single centre block. Larger builds (30+) look smoother because the pixel steps become smaller relative to the whole. Use the diameter you need and the generator handles the maths.

What does "thick" border mean?
The thick option renders a 2-block-thick outline instead of a 1-block-thick one, which is the standard for load-bearing walls in Minecraft round builds - the extra ring stops single-block gaps from looking jagged and helps redstone or lighting stay flush against the shape.

How many blocks are in a Minecraft circle?
It depends on the diameter and border thickness. The Details panel counts them for you and converts to full stacks of 64 and dye/potion stacks of 16 so you know exactly what to bring on your gathering trip.

Can I use this for spheres and domes?
Yes - build the circle at each y-level of your sphere using the diameter for that slice. A ~15-block-diameter sphere uses circles of diameter 3, 7, 11, 13, 15, 15, 15, 13, 11, 7, 3 from top to bottom. The generator lets you scan through diameters quickly to design each ring.

Is the Craftapedia circle generator free?
Yes - it is 100% free, runs entirely in your browser, requires no account, and never uploads your designs anywhere. Bookmark the page and use it as often as you want.
