Minecraft Circle Chart

Compare outer diameters using one consistent block boundary rule.

Compare circle sizes

Outline keeps the four-neighbor boundary. Filled includes every inside cell. Counts below are generated from those exact blueprints; a stack contains 64 blocks.

Outer diameters and materials
Diameter	Center	Outline blocks	Filled blocks	Outline stacks	Blueprint link
8 blocks	Four-cell intersection	20	52	0 stacks + 20 blocks	Open 8-block circle
10 blocks	Four-cell intersection	28	80	0 stacks + 28 blocks	Open 10-block circle
15 blocks	Cell	40	177	0 stacks + 40 blocks	Open 15-block circle
16 blocks	Four-cell intersection	44	208	0 stacks + 44 blocks	Open 16-block circle
21 blocks	Cell	56	349	0 stacks + 56 blocks	Open 21-block circle
24 blocks	Four-cell intersection	64	448	1 stacks + 0 blocks	Open 24-block circle
31 blocks	Cell	84	749	1 stacks + 20 blocks	Open 31-block circle
32 blocks	Four-cell intersection	88	812	1 stacks + 24 blocks	Open 32-block circle
48 blocks	Four-cell intersection	132	1804	2 stacks + 4 blocks	Open 48-block circle
64 blocks	Four-cell intersection	180	3228	2 stacks + 52 blocks	Open 64-block circle

Odd and even centers

Odd diameters: a center cell

15-block circle

21-block circle

31-block circle

Even diameters: a four-cell intersection

Choose a diameter for your build

Count the space from the first outside column to the last, including both ends. Leave extra room outside that footprint for paths or thicker walls you plan to add yourself.

The chart gives reference sizes. Use the circle generator for any diameter from 1 to 256, or follow the row building guide to lay it out.
