Triangular Graph Paper
A field of equilateral triangles with every line at 0°, 60° or 120°, so 30-60-90 geometry is drawn rather than constructed.

On squared paper a 60° line is an approximation you eyeball or set out with a protractor. On triangular paper it is simply the next line along. So is 120°, and so are all the reflections of both.
That turns a whole family of constructions into tracing: equilateral triangles, regular hexagons, rhombi, trapezia and every tessellation built from them.
The triangular lattice is the parent of several others — join alternate vertices and you have hexagons; take pairs of triangles and you have rhombi.
Every sheet here is free, adjustable and prints at exact scale.
Isometric paper adds vertical lines to the triangular lattice so you can draw upright edges of solids. Triangular paper leaves them out, which suits flat pattern work rather than 3D sketching.
Yes — six triangles round a shared vertex make a regular hexagon, so hexagonal tilings fall straight out of the grid.
8 to 12 mm is comfortable for pattern work. Go smaller for dense tessellations, larger for classroom demonstrations.
