About isometric graph paper
Isometric paper turns flat sketching into convincing 3D. The vertical and 30° diagonal grid holds cubes, pipes and buildings at consistent angles, which is why product designers, engineers and game artists keep it around.
The grid is built from vertical lines and 30° diagonals that meet at a true equilateral lattice, so cubes, pipes and rooms keep consistent angles as you draw. It is the go-to for 3D product sketches, isometric game art and piping diagrams where proportions must stay believable.
Draw vertical edges straight up and horizontal edges along the 30° lines; there is no foreshortening, so equal lengths stay equal in every direction. A lighter grid color keeps your linework readable on top.
Great for
- 3D product and concept sketches
- Isometric pixel / game art
- Engineering and piping drawings
- Architecture and interiors
Common questions
What angle is isometric paper?
The diagonals sit at 30° from horizontal, forming a true equilateral (isometric) grid.
How is it different from perspective paper?
Isometric keeps parallel lines parallel with no vanishing point, so it is faster for technical 3D; perspective paper converges to vanishing points for realistic depth.

Printing at the right size
Every sheet is drawn in real units, so it prints true to size as long as you print at 100%. In the print dialog, set the scale to 100% and turn off “Fit to page” or “Shrink oversized pages” — then a 5 mm square really measures 5 mm. Download a vector SVG to edit later, a PNG at up to 600 dpi, or a ready-to-print PDF. Everything is generated in your browser, nothing is uploaded, and every sheet is free to print for personal, classroom and commercial use. See the guide to printing at true size or the FAQ for more.
