Build a pillar to stand on
A temporary pillar at the centre gives you a fixed reference point and a place to stand while you work around each layer.

Minecraft Sphere Generator
This Minecraft sphere generator, or sphere maker, gives you every layer of a sphere as a blueprint, with the block count for each layer and the whole ball. Check the shape in 3D, cut it open at any layer and download it for Litematica, WorldEdit, Bedrock or as a world.

Hollow counts use a one-block shell.

How to build a sphere layer by layer
Set the diameter
The number of layers equals the diameter, so a 21-block sphere has 21 layers.
Start at layer 1
The bottom layer is a small disc. The blueprint shows the layer below in grey to help you line up.
Work upward
Use the layer slider or the + button after each layer. The middle layers are the widest.
Check in 3D
Open the 3D preview and turn on the cutaway to see exactly where your current layer sits.
Tips for building spheres
Build from the middle out for floating spheres
Start with the widest middle layer, then build the halves above and below it. The middle layer is a circle of the same diameter.
Glass needs a seal
Built from full blocks such as glass, both shells keep water out of an underwater base. The thin shell saves blocks; the default thick shell gives a bolder outline.
Large spheres: paste them
Above about 40 blocks a sphere has thousands of blocks. The .litematic and .schem downloads save hours.
Download formats
Every shape can be downloaded for the tool you already use.
Litematica (.litematic)
Put the file in .minecraft/schematics, open the Litematica menu with M and load it as a hologram to build over.
WorldEdit (.schem)
Put the file in the WorldEdit schematics folder, then run //schem load <name> and //paste. The shape is centred on you.
Bedrock (.mcstructure)
Load it with a structure block, or add it to a behaviour pack and use /structure load. Shapes wider than 64 blocks come as tiles.
Java world (.zip)
Unzip into .minecraft/saves and open it: a creative superflat world with your build in front of spawn.
PNG blueprint
A printable image with a grid, coordinates and centre lines. Spheres and domes also come as one sheet with every layer.
Frequently asked questions
How do you build a sphere in Minecraft?
Build it one horizontal layer at a time. Enter the diameter here, start at layer 1 and follow each layer blueprint upward; the layer below is shown in grey so you can line them up.
How many blocks are in a Minecraft sphere?
It depends on the size and whether it is hollow. A hollow 21-block sphere and a solid one have very different counts; the generator shows both the total and each layer.
What is the best size for a sphere?
Odd diameters give a single centre block and a single widest layer, which is easier to build. Spheres under 9 blocks look blocky; 15 and above look round.
Can I make a hollow sphere with thick walls?
Yes. Choose Hollow and raise the wall thickness. The inside stays empty and the count updates as you go.
Can I import the sphere into my world?
Download .litematic for Litematica, .schem for WorldEdit, .mcstructure for Bedrock, or a ready-made Java world with the sphere already built.
