How to print isometric paper
- Choose lines or dots. A triangle grid guides every edge; dots give a cleaner page.
- Pick the triangle size — 5 mm for detail, 1 cm or 1/2 inch for teaching.
- Download and print at 100%.
How isometric drawing works
In an isometric drawing, the three edges of a cube meet at 120°: verticals stay vertical, and the other two directions run at 30° above the horizontal, left and right. Lengths along all three directions use the same scale, so you can measure straight off the drawing. The grid gives you exactly those three directions: vertical lines and two families of 30° lines.
| Use | Suggested setting |
|---|---|
| Maths lessons on 3D shapes and nets | 1 cm, lines |
| Technical and product sketches | 5 mm, dots |
| Game maps and pixel-style art | 5 mm or 1/4 inch, lines |
| Architecture and room layouts | 5 mm, lines, light grey |
Tips
- Hold the paper so the vertical lines run up and down; that keeps the 30° directions correct.
- Draw the front corner first, then the three edges out from it, then close the shape.
- Use light grey or blue lines so they fade behind your drawing, or disappear when photocopied lightly.
Frequently asked questions
What is isometric paper used for?
Drawing 3D objects without perspective: technical and engineering sketches, architecture, product design, pixel-style game maps and maths lessons on 3D shapes.
Lines or dots?
Lines (a triangle grid) help beginners keep every edge at 30°. Dots give a cleaner page once you’re confident, because only your own lines show.
What size should I choose?
5 mm triangles suit detailed drawings; 1 cm or 1/2 inch suit classrooms and younger students.
Is the grid exact?
Print at 100% / Actual size (not “Fit to page”), otherwise the printer shrinks the page and the spacing is no longer exact.
