What is triangle grid paper?

Triangle grid paper uses three sets of evenly spaced lines to form repeating equilateral triangles. The grid provides accurate 60-degree directions and also makes hexagons, diamonds, and repeating geometric forms easy to construct.

Use it for geometry exercises, tessellations, quilting blocks, beadwork, mosaics, technical sketches, and pattern design. Smaller triangles suit detailed constructions, while larger triangles leave more room for coloring, labels, and classroom work.

Which paper size should I choose?

Check the size printed on your paper pack or shown in the printer tray. A4 is standard in most countries, while US Letter is standard in the United States and Canada. Choose a larger size only when your printer or print service supports it.

Which triangle size should you choose?

The choices below explain what changes and when each option is useful. Make the actual selection in the download panel at the top of the page.

5mm

A 5mm triangle grid creates a dense field for detailed tessellations, compact geometry, bead patterns, quilting plans, and fine technical sketches.

6mm

A 6mm triangle grid balances drawing detail and writing room for general geometry, pattern design, maps, diagrams, and classroom activities.

10mm

A 10mm triangle grid provides larger cells for bold constructions, labels, classroom demonstrations, quilting layouts, and designs that need more drawing room.

Point-up or flat-base grid phase?

The choices below explain what changes and when each option is useful. Make the actual selection in the download panel at the top of the page.

Point Up

The point-up option starts the diagonal line pattern in the phase that places an upward-pointing triangle at the upper grid edge.

Flat Base

The flat-base option shifts the first diagonal row by half a triangle side, changing the phase visible at the upper grid edge.

What is triangle grid paper used for?

Geometry and tessellations

Construct equilateral triangles, hexagons, 60-degree angles, transformations, and repeating tilings.

Craft and pattern design

Plan quilting blocks, beadwork, mosaics, embroidery, and other designs built from triangular units.

Maps and technical sketches

Lay out routes, structures, diagrams, and spatial systems that benefit from three drawing directions.
