Shape Generator

Minecraft Cylinder Generator

Build a perfectly round tower, silo, well, or pipe. Set the diameter and height — every layer is the same circle, so Hollow gives an open tube you can stack to any height, and Filled gives a solid pillar. Flip to the 3D view to rotate the finished tower and see it from any angle.

How to build a cylinder in Minecraft

  1. Set the diameter of the circle and the height of the tower.
  2. Build the ring shown once, then stack identical copies straight up for every layer — all layers of a cylinder are the same circle.
  3. Hollow is an open tube (no top or bottom). Add a filled circle of the same diameter as a roof or floor if you want to close it off.
  4. For the cap shape on its own, use the circle generator.

FAQ

How do you make a round tower in Minecraft?

Set the diameter for the tower's width and the height for how tall it is. The generator gives you one circle cross-section to repeat at every level — build that circle, then stack it straight up. Hollow mode is the open tube you want for walls you can stand inside.

How do you make a cylinder, silo, or pipe?

They're all the same shape — a circle extruded to a height. Use a wider diameter for silos, a narrow one for pipes, and Hollow for an open tube or Filled for a solid pillar. The block count updates live as you size it.

What diameter makes a clean round tower?

Odd diameters (7, 9, 11…) give a symmetric circle with a single-block center, which reads as the roundest. 9–13 is the sweet spot for castle and wizard towers; go wider for arena or silo walls.

What's the difference between a cylinder and a sphere?

A cylinder repeats the same circle at every height (straight sides). A sphere changes the circle size each layer so it curves in at the top and bottom. Use the Sphere generator if you want a ball or dome instead of a straight tower.
