Minecraft Sphere Generator

How a Minecraft sphere is built

A sphere in Minecraft is a stack of circles. The bottom layer is a small disc, each layer above it gets wider until the middle (the “equator”), and then they shrink again to a small disc at the top. A sphere with a diameter of 21 has 21 layers, and each one is a different circle.

Working out all those circles by hand is the hard part. The generator calculates every layer for you. Move the Layer slider to see each slice from above, then build it in your world and move up one block.

How to use the sphere generator

1. Set the diameter. Anything from 1 to 128 blocks. Odd sizes have a single centre block, which makes them easier to line up.
2. Choose hollow or solid. Outline makes a hollow shell one block thick (the usual choice). Thick adds more wall layers. Filled makes a solid ball.
3. Step through the layers. Start at Layer 1 (the bottom), build it, then move up. The Blocks counter shows how many you need for that layer only, and the Total shows the whole sphere.
4. Check it in 3D. Switch to 3D to see the finished sphere. The layer you are on is highlighted in gold.
5. Or skip the counting. Download the .litematic file and Litematica will show a hologram of every block in your world.

Step-by-step: building a sphere in survival

1. Pick the centre and note its coordinates (F3 on Java, “show coordinates” on Bedrock).
2. Build a pillar straight up from where the bottom of the sphere will be, as tall as the diameter. This is your guide for the height of every layer.
3. Build the middle layer first. It’s the widest, so it shows you the full size. Build it on scaffolding around the pillar.
4. Work outward from the middle. Build the layers above and below, one at a time, using the layer slider.
5. Close the top and bottom with the small discs, then remove the pillar and scaffolding from the inside.

How many blocks does a sphere need? Here is the exact count for popular sizes. Click a size to load it.

A hollow sphere uses far fewer blocks than a solid one: a 41-block hollow sphere needs about 4,200 blocks, while a solid one needs over 36,000. For big builds, always go hollow.

Hollow vs solid spheres

Our hollow spheres use the thinnest shell that has no holes: every block touches the outside on at least one face. It’s the same logic WorldEdit uses for //hsphere, so you get an airtight shell (great for underwater bases) with the fewest blocks possible.

Solid spheres are best for small decorations like orbs on top of towers, giant fruit, or boulders. For anything larger than about 15 blocks, hollow is cheaper and just as good-looking.

Sphere build ideas

• Glass underwater base: a hollow glass sphere at the bottom of the ocean. Build it, then drain the water inside with sponges or sand.
• Planets and moons: a space-themed world with spheres of different sizes and materials.
• Dragon eggs and giant orbs: small solid spheres (9–15 blocks) on top of towers or gates.
• Tree canopies: overlapping leaf spheres make round, natural-looking custom trees.
• Death Star or ball-shaped bases: a large hollow sphere with floors built inside.
• Mob-proof skyblock bubbles: a glass sphere floating in the sky as a safe home.

WorldEdit sphere commands

//sphere stone 10       solid sphere, radius 10 (21 wide)
//hsphere glass 15      hollow sphere, radius 15 (31 wide)
//hsphere glass 15,10,15  hollow ellipsoid (taller or flatter)

WorldEdit places the sphere centred on your feet. Stand where you want the centre before running the command. The radius is counted from the centre block, so radius 10 gives a 21-block sphere. WorldEdit can only make odd sizes. For even sizes, use the blueprint or the .litematic file.
