Thin
The fewest blocks and a lighter line. Full blocks still hold water and keep mobs out, but fences, panes and walls built on it leave gaps at the corners.

Printable reference
Find your diameter and print a circle template to build from. Browse diagrams from 3 to 64 blocks, or look up thin, thick and filled block counts from 1 to 128.
Thin outlines shown. The number is the block count for that outline.
Thin: blocks joined at corners. Thick: blocks joined along edges (the generator default). Filled: a solid disc.

The fewest blocks and a lighter line. Full blocks still hold water and keep mobs out, but fences, panes and walls built on it leave gaps at the corners.
Every block touches the next along an edge, for a bolder line. Use it for towers, and for fences, panes or walls, which only join side to side.
A solid disc for floors, platforms and the base of a sphere.
Each square in a blueprint is one block seen from above. Find your diameter, mark the centre in game and copy the rows.
Charts round the circle edge differently. This one places every block whose centre is inside the true circle, the most common rule, and lists thin, thick and filled versions.
Yes. Use Print chart on this page for every circle diagram from 3 to 64 on paper, or download a PNG of any single size from the circle generator.
The generator goes up to 256 blocks and adds ovals, spheres and domes.
