Put this page to work.

Connect adjacent points to create triangles, diamonds, or hexagons. Each triangle has three equal edges, so repeating steps preserve a consistent scale.

The measurement to know: equilateral-triangle edge length. Row height equals the chosen edge length × √3 ÷ 2. Alternating rows are offset by half an edge to make the triangular lattice.

On this sheet: triangle edge: 20 mm; row height: 17.32 mm; dots: 112. The drawing area is 156 × 230 mm.

ISO B5 is 176 × 250 mm. This differs from Japanese JIS B5 (182 × 257 mm). Changing the paper size adjusts the available area; the selected pattern measurement stays the same.
