Custom grid generator
The 576 templates in the library cover the common combinations. If you need a pitch, colour or paper size that isn't one of them, build it here: pick a grid family, dial in the exact spacing and sheet, and download a print-ready SVG in seconds. Nothing is uploaded - the file is generated in your browser.
How this generator works
Every field maps directly onto the SVG that gets drawn: pitch is the true centre-to-centre spacing in millimetres, margin is the blank border kept clear of grid lines (useful for hole-punching or binding), and the paper sizes match the ISO 216 and ANSI sheets used across the rest of the library. The file downloads as a vector, so it prints crisply at any size and stays editable in Illustrator, Inkscape or Affinity Designer if you want to add your own linework on top.
Choosing a grid family
Square is standard graph paper - good for plans, charts and general sketching. Dot grid gives you alignment points without the visual weight of solid lines, popular for bullet journals and light layout work. Engineering is a square grid with a heavier line every N squares (5 by default), the convention used on quadrille pads for quick order-of-magnitude reading. Isometric draws three line families 120° apart for 3D sketching and technical illustration. Hexagonal tiles flat-top hexagons for tabletop maps, wargaming terrain and cellular diagrams.
Printing at true size
Open the downloaded SVG in your browser or vector editor and print at 100% / actual size - never "fit to page", which rescales the pitch. The how-to-print guide covers the calibration check that catches printers which silently shrink the page by a few percent.
Prefer a ready-made sheet?
If your spec matches one of the common combinations, the pre-built library is one click with no setup: browse by grid type, paper size, or profession. Working at an odd scale ratio instead of a fixed grid? Use the scale calculator to convert drawing to real-world dimensions first.
