A 31 block Minecraft circle is a strong general-purpose size for towers, arenas, domes, and server hub details. It gives a smoother curve than small circles without becoming a mega-build footprint.
Build one quadrant, mirror the rows, and use the preset for coordinates and PNG export.

31 block circle row counts
The row pattern is the part most builders miscount. Use the outline counts below when building a wall, tower, or ring. Use the generator preset for coordinates and PNG export.

If the build needs a dome, use this circle as the bottom layer and shrink upper layers.

Start from the center point and build one quadrant first.
3. Mirror the rows
Mirror the quadrant on both axes so every side stays symmetrical.
