Printable graph paper / Isometric paper
Isometric paper, printable
Vertical lines plus two sets of lines at 30° to the horizontal, which makes a grid of equilateral triangles. Every edge of a cube drawn in isometric projection lands on a line.
What it’s good for
3D shapes and nets in geometry, game-level and pixel-art sketches, and furniture or room layouts.
Every option above can be changed: swap Letter for A4, change the line colour to a pale blue that photocopies faintly, or turn on landscape. The PDF is rebuilt instantly in your browser and nothing is uploaded.
Prefer to draw on screen? The online graph paper board has the same grids with markers and snapping lines.
Questions people ask
What is the difference between isometric paper and isometric dot paper?
Isometric paper shows full lines; isometric dot paper shows only the points where lines would cross. The lined version is easier for beginners, the dotted one gives a cleaner finished drawing. This page prints the lined version; the dot grid preset prints square-spaced dots.
How do I print it at the correct size?
Choose “Actual size” or 100% scale in the print dialog. “Fit to page” shrinks the grid by a few percent.
