Minecraft Shape Generator
Pick a shape, type its size and get a block-by-block plan: a numbered grid for every layer, the block count for each layer and in total, and a 3D preview you can turn. Save the grid as a PNG, the shape as an STL, or copy a WorldEdit command. It runs in your browser.
Guides for each shape

- Pixel Circle GeneratorA pixel-perfect circle for sprites and pixel art, saved as a PNG with a transparent background.
- Minecraft Sphere GeneratorSolid or hollow spheres and ellipsoids, shown layer by layer from the bottom up.
- Minecraft Dome GeneratorDomes with a round or elliptical base and your own height, solid or hollow.
- Minecraft Arch GeneratorRound, pointed and shallow arches with span, rise, thickness and depth.
- Minecraft Spiral Staircase GeneratorSpiral stairs with a chosen radius, height, turn direction and steps per turn.
- Minecraft Pixel Art GeneratorTurn an image into a block-by-block pixel art plan.
- Minecraft Map Art GeneratorPlan map art from a picture with a block palette.
- Minecraft Block Palette GeneratorBuild a block palette that matches the colours of an image.
How to use the Minecraft shape generator
- 1
Pick a shape
Choose a circle, oval, sphere, dome, cylinder, cone, pyramid, torus, polygon, arch or spiral staircase with the buttons above the inputs.
- 2
Enter the size
Type the width, height or radius in blocks. Odd sizes have a single centre block; even sizes have a 2 by 2 centre. The tool shows the total block count at once.
- 3
Read it layer by layer
Move the layer slider to see each slice from the bottom up. The grid marks the centre, and the row counts list how many blocks to place in each row.
- 4
Build it or save it
Build from the grid, copy the WorldEdit command for the odd sizes it supports, or download a PNG of the plan or an STL for 3D printing.
What each shape is good for
Eleven shapes share the same tool. These are the common builds for each one.
| Circle, oval, polygon | Flat plans from above: towers, ponds, plazas, arenas and the footprint of a round room. |
|---|---|
| Sphere | Planets, globes, glass orbs and the outline of a rounded tower top. Solid or hollow. |
| Dome | Roofs for observatories, greenhouses, temples and bases. Sits flat on its base layer. |
| Cylinder and cone | Towers and silos (cylinder), witch hats and spires (cone). |
| Pyramid | Stepped pyramids and roofs, with a square or rectangular base. |
| Torus | Rings, hoops, portals and donut-shaped halls. |
| Arch | Doorways, bridges, windows and gateways. Round, pointed or shallow. |
| Spiral staircase | Stairs inside a tower or around a pillar, with your own turn direction. |
Flat shapes: circle, oval and polygon
A circle in Minecraft is a ring of square blocks that looks round from far away. The trick is that every layer of a big build is the same flat circle, so a good plan of one layer is most of the job. The circle generator draws it for any diameter, and the oval generator lets the width and height differ. Both can draw a thin outline, where blocks touch at the corners, a thick outline, where they touch along edges, or a filled disc for floors.
Odd and even sizes behave differently. An odd diameter has one block at the centre, which is handy for a pillar, a beacon or a ladder. An even diameter has a 2 by 2 centre and cannot hold a single middle block, but it is often the better choice when you want a wide, symmetric doorway. The tool says which one you picked. The polygon option draws any regular shape from 3 to 16 sides, such as the hexagon or octagon floor of a gazebo.
Round solids: sphere, dome, cylinder, cone and torus
Solid shapes are built from layers. A sphere is a stack of circles that grow and then shrink; a dome is the top half of a sphere, standing flat; a cylinder repeats one circle; a cone shrinks it layer after layer; and a torus is a ring made from a round tube. Use the layer slider to move through the stack, and the 3D preview to see the whole shape. The hollow option keeps only a one-block shell, which saves a lot of blocks for big builds.
The block count matters more than most players expect. A solid sphere that is 31 blocks across needs over fifteen thousand blocks, while the hollow version needs only a couple of thousand. The tool shows the total, so you can plan your materials before you place the first block, and the count for each layer so you can build one slice at a time.
Arches, pyramids and spiral stairs
Arches and stairs are the shapes that are hardest to eyeball. The arch generator makes a round, pointed or shallow arch with the span, rise, wall thickness and depth you choose, and shows the front view with the number of blocks in each row. The spiral staircase generator places each step around a centre pillar, with the radius, height, steps per turn and turn direction you choose, so the stairs line up and you can walk them without a jump gap.
Pyramids are simple but easy to get wrong at the top. The tool lets you pick any base and height, and a button sets the height to half the base for the classic 45 degree sides. When a shape matches a WorldEdit command, such as a sphere, a cylinder or a pyramid, the tool writes the command for you. Everything runs in your browser and nothing is uploaded.
