Free Printable Isometric Paper
A triangular 30° grid for 3D sketching, technical drawing and game maps — set the line spacing, then print to PDF on Letter or A4. Free, no signup.
About this free printable isometric paper
This generator makes free printable isometric paper as a PDF — a triangular 30° grid for drawing in 3D. Set the triangle size (5 mm means 5 mm between grid points, the standard way isometric paper is sized), choose a triangular grid (with verticals) or a diamond grid (without), pick the line color, and the page size. It's drawn as crisp vector graphics, so the grid stays sharp and prints at its true spacing on both Letter and A4.
How to draw on isometric paper
- Draw vertical edges straight up the vertical lines.
- Draw width and depth along the two 30° diagonal directions.
- Heights stay vertical; the diagonals keep every face at the correct isometric angle.
- Build up cubes and boxes first, then add detail — the grid keeps proportions true.
What people use it for
3D and technical sketching, engineering and product design, architecture, isometric pixel art, and tabletop game maps and dungeons. Design-and-technology classes use it to teach isometric projection. If you need a flat square grid instead, use graph paper or dot grid paper. Because you can set the spacing and print instantly, you always have the right grid.

Frequently asked questions
- What is isometric paper?
- Isometric paper is grid paper ruled with three sets of parallel lines instead of squares, forming a field of equilateral triangles. The angled grid lets you draw 3D objects in isometric projection — where the three axes are evenly spaced — so cubes, buildings and machines look correctly proportioned.
- What angle is isometric paper?
- True isometric paper uses lines at 30° above horizontal (and their mirror), with optional verticals. Those 30° angles give the standard isometric look where all three axes are 120° apart. This generator uses 30° by default.
- How do I use isometric paper?
- Draw vertical edges along the vertical lines, and horizontal-looking edges along the 30° lines. Heights go up the verticals; width and depth follow the two diagonal directions. The triangular grid keeps every face at the correct isometric angle, so 3D shapes stay proportioned.
- What is the difference between triangular and diamond isometric grids?
- Triangular (true isometric) includes the vertical lines, splitting the page into equilateral triangles. Turning verticals off leaves only the two diagonal families, forming a diamond grid — handy for some pattern and lettering work. Use the verticals toggle to switch.
- What is isometric paper used for?
- 3D and technical sketching, engineering and product design, architecture, isometric pixel art, tabletop game maps and dungeons, and drawing cubes, prisms and cylinders. It's a staple in design and technology classes.
- Is it free, and does it work on Letter and A4?
- Yes — completely free, no signup. Choose US Letter or A4, portrait or landscape, and the isometric grid prints at its exact spacing.
