Generate pixel-perfect circles for your Minecraft builds.
Blocks Needed
Diameter
15x15
Each square = 1 Minecraft block
Tips: Use odd numbers for perfect symmetry. For spheres, build multiple circles of decreasing size on each layer.

Minecraft only has square blocks, so circles are pixel-art approximations. The GBNodes Circle Generator uses the midpoint circle algorithm to calculate the optimal block placement for circles from 3 to 64 blocks in diameter.
Use hollow circles for outlines (towers, windows, arenas) and filled circles as platforms or floors. Tip: odd diameters like 15, 21, or 31 produce more symmetric results.
Use a circle generator to calculate block positions using the midpoint algorithm. Place blocks at each plotted point. Odd diameters give the most symmetric results.
Odd-numbered diameters (15, 21, 31) produce more symmetric circles. For large builds, 32 or 64-block circles are popular. Use the quick size buttons to preview each size instantly.
Stack circles of decreasing size. Use r = sqrt(R² - h²) to calculate the radius of each layer (R = sphere radius, h = height above center). Start with the widest circle at the center and reduce diameter per layer.
