Eight millimetres separates one rule from the next, twenty-three lines down an A5 page. That is the whole specification: no dot, no box, no margin column, just a line to write against. It sits between the two named rulings on this shelf, finer than wide and coarser than college.

A pitch this size holds an ordinary hand without crowding it and without leaving so much air above the line that a page looks half-finished. It is drawn as vector geometry rather than a tiled image, so the rule holds its edge at any zoom and the file stays small enough to matter.

It is a pitch, not a philosophy. There is nothing else on the page to argue about.

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 Lined Notebook 8 mm shown as cards: a ruled page, a section divider, a conversion table, an emergency page, and a world map page.
Five pages rendered straight from the print file: a ruled page, a divider, a conversion table, the emergency page, and the world map page at the back. Every rule is geometry, not a bitmap, which is the difference between a line that stays crisp and one that goes soft the moment somebody zooms in.
Specification card for the Lined Notebook 8 mm listing 132 ruled pages at 8.00 mm, 23 lines per page, 140 pages total, A5 trim.
One hundred and thirty-two pages ruled at 8.00 mm, twenty-three lines each, vector throughout so the file stays small. Eight pages of reference matter close the book: conversion tables computed from definitions, emergency numbers checked against two independent sources. One hundred and forty pages total, A5, seven sewn signatures of twenty.

Questions

What is the line spacing?

8.00 mm, measured off the finished page.

How many lines per page?

23, down an A5 page.

How does 8 mm compare to wide or college ruling?

Finer than the wide rule on this shelf, coarser than the college pitch.

Is it dated?

No.

Is the ruling printed as an image?

No. It is vector geometry, so it holds its edge at any zoom and keeps the file small.

There is another experiment by which I will shew you its weight.
Michael Faraday, The Chemical History of a Candle, 1861
