Printable Equilateral Triangle Grid Paper

Equilateral Triangle Paper: Printable Triangle Grid for Isometric Drawing & Art

Equilateral triangle paper covers the page with a grid of equilateral triangles — each side equal, each angle exactly 60°. This makes it the go-to paper for isometric drawing, tessellation art, 3D cube sketching, and geometry class. Because three triangles meet perfectly at every vertex, the grid also functions as a hexagon grid: connect every other set of triangles to reveal the hexagons hidden inside.

Isometric Drawing & 3D Sketching

The 60° grid is the foundation of isometric projection — the drafting technique that shows objects in three dimensions without perspective distortion. Architects, product designers, and game artists use isometric grids to sketch cabinets, buildings, and pixel-art environments. With equilateral triangle paper you can:

• Draw 3D cubes, crates, and staircase structures by following the three axis directions of the grid.
• Sketch isometric room layouts or dungeon maps for tabletop RPGs — every corridor stays perfectly aligned.
• Design pixel-art sprites or level maps in a clean isometric style without graph software.

Prefer dots to lines? Our isometric dot paper gives the same 60° grid as light reference dots that stay invisible once you draw over them.

Tessellation, Geometry & Art

• Tessellation art – equilateral triangles tile the plane perfectly. Color alternating triangles to build hexagons, Stars of David, pinwheel patterns, or Escher-inspired creatures.
• Geometry class – hands-on proofs for the interior angle sum of polygons, symmetry groups, and the relationship between triangles and hexagons.
• Quilting & patchwork – the 60° grid mirrors the classic "grandmother's flower garden" hexagon quilt layout; plan your fabric colors before cutting.
• Origami planning – sketch fold lines for modular origami units that assemble into 3D polyhedra.
