Isometric Graph Paper
Isometric graph paper has three sets of parallel lines at 60° to each other, forming a regular field of equilateral triangles. It is the standard for 3D sketches, isometric pixel art, and technical drawing. Generate it on Letter or A4, print, or download a vector PDF.
What is isometric graph paper?
- Three line directions at 60° apart — one vertical, two at 30° from horizontal — let you draw three faces of a cube on a flat page.
- Every triangle on the page is equilateral, so all distances along the grid lines are equal.
- The classic spacing is ¼ inch (~6.35 mm) or 5 mm for a metric grid.
What is it good for?
- Isometric pixel art and game-asset sketches.
- Architectural and engineering perspective sketches.
- Lego, voxel, and 3D-printed model planning.
- Tabletop dungeon maps in isometric perspective.
Isometric vs triangular vs hex
- Isometric — three line directions; great for 3D drawings.
- Triangular — same triangle field, but rendered as filled-in triangles rather than continuous grid lines.
- Hexagonal — hexagons rather than triangles; popular for tabletop maps and board games.
Frequently asked questions
What angle is isometric graph paper?
The two non-vertical line directions sit at 30° above the horizontal, with a 60° angle between any two adjacent lines.
Is isometric the same as 3D graph paper?
Yes, informally. "Isometric" is the standard technical term; "3D graph paper" is how it is often described in art and craft contexts.
What spacing should I pick?
¼ inch (0.25 in) on Letter or 5 mm on A4 are the standard defaults. Pick a finer spacing for detailed pixel art and a coarser one for big sketches.
Can I print it on landscape paper?
Yes. Switch orientation to Landscape in the generator and the isometric field will fill the rotated page.
Does it work for game maps?
Yes. Many isometric board games and RPGs use a 1 cm or ½ inch grid; both are one click away in the generator.
