Minecraft Sphere Chart

This Minecraft sphere chart is a lookup table. Each row of the table is one sphere diameter. Layers is how many horizontal layers the ball has: a sphere is as tall as it is wide. Hollow sphere is the block count of the one-block-thick shell, which is what most builds need, and Solid sphere is every block inside the ball. The stacks columns divide each total into stacks of 64 blocks with the remainder, so you can see how many stacks to collect before you start.

The last two columns are for the dome, the top half of the sphere. A dome of the same width has about half the layers and a little more than half the blocks, because the layer with the widest ring is counted once. Click a diameter to open the hollow sphere in the generator, or click the solid count or the dome to jump to that version.

Above the table, each drawing is the sphere cut open through the middle: the row of blocks along the middle of every layer, top layer first. The wall of a hollow sphere is one block thick, so the drawing shows the same block outline you see when you dig through the middle of a build. The number under each drawing is the diameter and the hollow block count.

Small spheres from 5 to 9 blocks make orbs, streetlamps and lanterns. Sizes 11 to 21 suit rooms, fountains and tower tops. Sizes 31 to 45 make observatories, planets and glass domes for a base. Above 50 the block counts climb fast: a 64-block hollow sphere takes 10,464 blocks, and a solid one takes 137,376, which is 2,146 stacks of 64.

An odd diameter has a single block in the exact middle. That matters for a beacon, a spawner or a light in the centre of a room. An even diameter has a 2 × 2 × 2 middle. Neither is better; the Minecraft sphere chart counts both kinds.

Hollow spheres on this Minecraft sphere chart are one block thick. If you need a thicker wall, open the sphere generator and choose the shell thickness, which is drawn with the same engine and adds a second or third skin on the inside. To hollow a solid sphere you have already built, subtract the hollow count from the solid count on this chart: a 32-block sphere has 17,256 solid blocks and 2,568 in its shell.
