Graph Paper Generator

Because the paper is generated at true physical dimensions, and any 'fit to page' or 'shrink to printable area' setting rescales it — a 5 mm grid silently becomes ~4.8 mm, which ruins anything measured against it. In the print dialog, set scale to 100% / Actual size. Borderless isn't needed; the layout already keeps a printer-safe margin.

US school graph paper is the 1/4-inch quad; engineering pads use 5 mm with a heavier line every fifth square (the toggle here) so you can read 25 mm blocks at a glance; 1 cm suits younger students and large plots. Metric countries default to 5 mm — if you're matching an existing notebook, measure one square.

It guides without dominating: dots align handwriting, tables, and sketches like a grid does, but visually disappear behind your ink — which is why bullet journals standardized on it (typically 5 mm spacing, matching the option here). It's also the favorite for interface sketching, where full gridlines fight the drawing.

The triangular grid gives you three axes at 120° — verticals plus two 30° diagonals — so 3D objects draw in correct isometric projection by just following the lines: heights along verticals, depth and width along each diagonal family. It's the standard for technical sketching, Minecraft-style plans, and engineering drawings without CAD.
