Triangle Graph Paper
Triangle graph paper fills the page with equilateral triangles, ready for tessellations, beadwork patterns, Truchet tiles, and geometric art. It uses the same underlying lattice as isometric paper but renders the lines closer to the triangles for a cleaner look. Print or download a vector PDF.
Triangle vs isometric
- Both are based on the same equilateral-triangle lattice.
- Isometric paper emphasizes the three directions for drawing 3D objects.
- Triangle paper emphasizes the triangle shapes themselves — better for tessellations and 2D pattern design.
What is it good for?
- Tessellation studies and tile patterns.
- Quilt design and patchwork planning.
- Bead-loom and peyote-stitch patterns.
- Triangle-grid mazes and puzzles.
- Origami crease patterns (especially flagstone and waterbomb bases).
Spacing choices
- ¼ inch (0.25 in) — dense; great for small pattern studies.
- ½ inch (0.5 in) — comfortable for quilt and beadwork planning.
- 1 cm or 2 cm — metric defaults; pair well with A4.
Frequently asked questions
How is triangle paper different from isometric paper?
They share the same lattice. Triangle paper highlights the triangles; isometric paper highlights three direction lines, which makes it easier to draw 3D objects.
Can I change the triangle size?
Yes. The spacing input controls the side length of each triangle. Lower values produce denser grids.
Will all the triangles be the same size?
Yes — every triangle on the page is equilateral and identical, so the grid is true to scale in all three directions.
Can I use triangle paper for tessellations?
Yes. It is one of the standard substrates for designing periodic tessellations and Truchet-tile patterns.
What paper size is best?
Letter or A4 are both fine. For wall-sized pattern studies, switch to Tabloid (11 × 17 in) or A3.
