Minecraft line spacing

Segment length and number of marks — the generator spaces them evenly and spreads the remainder so gaps differ by at most one block: torches along a wall, fence posts, lanterns on a road, bridge pylons. Two blocks: line and mark. In 3D at once, export to .litematic and .schem.

How it works

1. Set the dimensions with the sliders — the shape is recalculated instantly and shown in 3D.
2. Pick a block (some tools take two: main and secondary).
3. Turn on Layers to see the shape slice by slice — handy for building by hand.
4. Download .litematic for Litematica or .schem for WorldEdit.

Examples

• 5 torches over 32
• Posts: 7 over 48
• Dense: 9 over 16

FAQ

What happens to the remainder when the length does not divide?

You get gaps of two sizes that differ by one block, alternated evenly — to the eye the spacing looks regular.

How do I build this without mods?

Open the schematic in the viewer, turn on Layers and place blocks layer by layer on the grid. With Litematica or WorldEdit the schematic is pasted in one go.

Why does the shape look stepped?

Blocks are whole, so every curve turns into steps — the game does the same. An odd size gives a clean centre block, an even size gives two.

Is it free, no sign-up?

Yes. Everything is computed in the browser; the file is built locally and never uploaded.
