Minecraft Circle · Sphere · Oval Generator
Enter a size to see circles, filled circles, ovals, spheres and domes as a block-by-block blueprint. For spheres and domes, step through each layer and build it exactly as shown.
Blue squares are where blocks go. The red dashed lines mark the center; for even sizes the center falls between two blocks.
How to build a circle in Minecraft
- Choose Circle and enter the diameter. Odd sizes (e.g. 15) have a single center block, which is easier to line up.
- Mark the center in your world, then count blocks outward along one quarter of the blueprint. Circles are symmetric, so the other three quarters mirror it.
- Turn on "Bold line every 5 blocks" to make counting easier on large builds.
Spheres and domes
Pick Sphere or Dome and use the layer slider (or ▼/▲) to go through each horizontal slice from the bottom up. Build one layer, step up, and build the next. The block count includes every layer so you can gather materials beforehand; with "Filled" off only the shell is counted.
FAQ
What does "Thick outline" do?
A thin outline only touches at corners on diagonal sections, which lets mobs and light through and looks dotted from far away. Thick outline adds blocks so every block shares a side with the next one.
What’s the largest size?
Up to 200 blocks. Blueprints above about 100 are easier to read zoomed in on a desktop screen.
