Isometric paper

A triangular grid for drawing in three dimensions.

Isometric paper is ruled with three sets of parallel lines at sixty degrees to each other, forming equilateral triangles. That geometry lets you sketch three-dimensional objects at a consistent scale without any perspective distortion.

2 spacings, two paper sizes

Every sheet is drawn as vector geometry at an absolute measurement. Print at 100% scale and the spacing on the paper is the spacing on the label.

What it is for

  • Sketching 3D objects, packaging and furniture at true scale
  • Technical and engineering drawing without perspective
  • Isometric pixel art and game-tile design
  • Quilting, tiling and tessellation patterns

Print at 100% scale

This is the one setting that matters. Choosing “fit to page” rescales the sheet and the spacing no longer matches the label — a 5 mm grid comes out at 4.7 mm and every measurement taken from it is wrong. Set scale to 100% and pick the paper size that matches your printer. The print guide covers the rest.

Common questions

What is isometric paper used for?
Drawing three-dimensional objects so that all three axes stay at the same scale. Unlike perspective drawing, a line of a given length represents the same distance wherever it sits on the page, which is what makes it useful for technical work.
What angle are the lines?
Thirty degrees above horizontal in each direction, plus verticals — which produces equilateral triangles and the characteristic 120-degree corners of an isometric cube.
Can I use it for pixel art?
Yes. Isometric tile art maps directly onto the triangular grid, which is why the format is common in game design as well as engineering.
