Minecraft Cylinder Generator (Java & Bedrock)

A cylinder is the same ring stacked on every layer. A 15-block round tower uses 56 blocks per layer, so 10 layers take 560 blocks.

Blocks for round towers (hollow, solid wall)

Diameter	Blocks per layer	Hollow, 10 tall	Filled, 10 tall
5	16	160	210
7	24	240	370
9	32	320	690
11	40	400	970
15	56	560	1,770
21	80	800	3,490
25	96	960	4,890
31	120	1,200	7,490

Counts come from the same generator as the tool above, so they always match the grid.

How to use it

Set the width (diameter) of the tower and how many blocks tall it should be.
Build layer 1 from the grid. Every layer above it is identical.
Turn on Oval for an elliptical tower, then set a different depth.
Use Filled for a solid pillar, or Hollow for a tower you can walk inside.
Copy the grid as text or download the PNG so you can keep it open while building.

How it works

Each block is placed if its centre falls inside the perfect shape that fits your size exactly. Hollow shapes keep only the blocks within your chosen wall thickness of the outside, so walls never have gaps. Every number on this page is calculated, not typed by hand.

Questions

Is a cylinder just a circle repeated?

Yes. Every layer of a straight cylinder is the same circle, so you only need to learn one layer and repeat it upwards.

Does this work for Minecraft Bedrock and Java?

Yes. Blocks are the same size in Java and Bedrock, so the same layout works in both editions and in every version.

Why is the centre a 2×2 square on even sizes?

An even diameter has no single middle block, so the centre falls between four blocks. Use an odd size (like 25) if you want one middle block to build from.
