Triangle Grid Paper
Triangle grid paper is printed with three line families that cross into a lattice of equilateral triangles. Download triangle grid templates in 7 sizes for tessellations, quilting and geometric patterns — free as PDF, PNG or SVG.
Key takeaways
- The three line families run at 0°, 60° and 120°, forming 60° equilateral triangles.
- The cells pack evenly in every direction, so patterns repeat without gaps.
- All triangle grid downloads are free and print at true scale.

How to use triangle grid paper
What is triangle grid paper?
Triangle grid paper is printed with three families of lines that cross into a lattice of equilateral triangles. Every triangle has three equal sides and three 60° angles, so the cells pack evenly in every direction. Designers use it for tessellations, geometric patterns and 3-D sketches.
Drawing tessellations
An equilateral triangle tiles the plane on its own, and combining triangles builds hexagons, diamonds and stars. Trace triangles repeatedly to make repeating patterns for quilting, tiling and surface design.
Choosing a triangle size
The spacing sets the triangle size. 5 mm is standard for detailed patterns, while 1 cm suits larger tessellations and classroom geometry. The three line angles stay fixed regardless of spacing.
Triangle grid vs isometric grid
The two use the same three line angles, so the cells look identical. Triangle paper is sold for flat geometric patterns, while isometric paper is labelled for 3-D drawing — the difference is mainly how you use it.
Triangle Grid Paper sizes and spacing
| Option | What it gives you | Best for |
|---|---|---|
| 2 mm | Fine, dense triangles | Detailed patterns and technical work |
| 5 mm | Standard pattern grid | Tessellations and design |
| 1 cm | Large, easy-to-trace cells | Quilting and classroom geometry |

FAQ
What is triangle grid paper used for?
It is used for geometric drawing, tessellations, quilting patterns and technical sketches that need equilateral triangles.
What angle are the lines on triangle grid paper?
The three line families run at 0°, 60° and 120°, so they meet to form equilateral triangles with 60° corners.
Is triangle grid paper the same as isometric grid paper?
They use the same three line angles, so the cells look alike. Isometric paper is labelled for 3-D drawing, while triangle paper is used for flat patterns.
Which spacing should I use for triangle grid paper?
5 mm is standard for detailed work, and 1 cm suits larger tessellations and classroom geometry.
Are these triangle grid downloads free?
Yes. All triangle grid PDF, PNG and SVG files are free to download and print with no login.
Can I draw 3-D sketches on triangle grid paper?
Yes. Because it uses the same 0°, 60° and 120° line families as isometric paper, you can sketch cubes and other 3-D objects along those three axes.
