Circle generator
Pixel-perfect circles, ovals, spheres and domes for building in Minecraft. Every square is one block.
Shape
Odd sizes have a single centre block; even sizes have a 2×2 centre. Tip: odd sizes are easier to line up with a doorway.
Blueprint
Row by row (for building and screen readers)
How to build a circle in Minecraft
Minecraft has no round blocks, so a circle is made of short straight runs of blocks. The blueprint shows exactly which blocks to place: build the outline one row at a time, counting the blocks in each run, and mark the centre first so both halves match.
Thin or thick walls
A thin wall touches only at the corners of the blocks, so mobs and light can pass through the diagonal gaps. A thick wall closes those gaps: use it for walls you can walk along or that must keep mobs out.
Spheres and domes
A sphere is a stack of circles that get smaller towards the top and bottom. Move the layer slider and build one floor at a time from the bottom up; a dome is the top half of a sphere. For big spheres, build the widest middle layer first and use it as a guide.
About this tool
How do I make a perfect circle in Minecraft?
Pick the size in the circle generator and copy the blueprint: build one row at a time, counting the blocks of each run. Start from the centre so both halves match.
How many blocks do I need?
The generator counts the blocks for the circle or for every layer of a sphere or dome, and shows the total in stacks of 64.
Should I use an odd or even size?
Odd sizes have a single centre block, so they line up easily with a door or a path. Even sizes have a 2×2 centre.
