Minecraft pixel circle size chart

Block counts by diameter

All figures are for a circle (width = height = diameter). For an oval, or any size not listed here, use the generator directly — it computes the exact same numbers for any width and height from 1 to 128.

How to read this chart

• Thin outline is the block count for a one-block-wide ring — the cheapest way to mark the shape out.
• Thick outline also fills the diagonal "pinch points" a thin ring leaves where the curve turns a tight corner, using more blocks for a visually sturdier line.
• Filled (disk) is every block inside the circle, for a solid floor, ceiling, or cross-section rather than a ring. It's always the largest number in the row, and always at least as large as either outline figure for the same diameter.
• All three columns are for one flat layer. Multiply by however many layers tall your build is for a full materials count — a dome or sphere needs a shrinking footprint per layer rather than the same one repeated, which this chart doesn't attempt to plan.

Picking a size

There's no fixed rule for what diameter to use — it depends on the space you're building into — but a few things are worth knowing before you commit to a number:

• Odd diameters have a single centre block and come to a one-block point at the top, bottom, left and right, which tends to read as slightly more "circular" at a glance.
• Even diameters have no centre block; the four extremes are flat two-block edges instead of a point. Neither is wrong — they're just two different valid ways a circle lands on a grid.
• Diameters below about 5 round to a shape indistinguishable from a filled square, because there isn't enough room for the corners to actually get cut. If you specifically want something that reads as round rather than square, start from 5 or larger.
• Doorway and window openings are usually easier with a diameter that's odd and small (5, 7, 9), since the single centre column lines up cleanly with a wall segment.
