A column of figures added by hand drifts sideways without something to hold it straight. A small diagram drawn freehand does the same thing in two directions at once. Thirty rows of 6.0 mm squares fill the page and hold both still.

That pitch sits between two others on the same shelf: a finer grid built for charting stitch by stitch, and a coarser one built to leave room for a whole word inside a square. Six millimetres is the middle setting, tight enough for a grid of small numerals and loose enough not to fight a pencil line.

The grid does not add the column up correctly. It only keeps each digit under the one above it, so a mistake is at least easy to find.

The film

Page by page

A vertical film from our own bench — this page contacts nobody's server to play it, and downloads nothing until you press play.

A vertical film, 52 seconds: the cover, the ruling page, then 5 reference pages. Synthesised ambient bed, no dialogue — captions in three languages.

Real pages

Five pages from the Squared Notebook 6 mm laid out as cards: a squared page, a conversion table, an emergency page, a world map page, and the pen test page.
Five pages rendered straight from the print file: the squared page, a conversion table, the emergency page, the world map, and the pen test leaf at the back. Every square is drawn as geometry, not tiled from a bitmap.
