Narrow ruled is a phrase most stationery aisles print on the cover and never explain. Here it is a quarter of an inch between lines, 6.35 millimetres, twenty-seven rows down the page. That is the actual US paper standard behind the words, not a rounded guess at it.

The pitch comes from the definition itself: one quarter of an inch, which is 6.35 millimetres, not a figure rounded off a printed page after the fact. Every rule on the page is vector geometry, plotted rather than photographed from a tile, so a hairline this fine never turns into a blur when the page is magnified.

It sits between the other two American rulings on this shelf: wider on one side, narrower on the other. This is the one most people mean by narrow without ever saying the number.

In every book

The same six pages open every book: your details, who to call, the signs to point at when you have no shared language, and the map. They sit at the front because the moment you need them is not the moment to be flicking through.

This book belongs to
One page for your name and number, so a book that goes missing can come back.
My details
Blood group, allergies, who to call. Written once, carried everywhere.
Emergency numbers
Forty countries, taken from Wikidata property P2852 (CC0), agreed across two sources, every row carrying its QID. Numbers change and a book does not — verify locally on arrival.
Point at this
A pictogram grid captioned in English above and Indonesian below, for when there is no shared language.
World map
Natural Earth 110m, public domain, equirectangular, with UTC hour meridians computed from the projection rather than from a timezone database. For orientation and for pointing at, not a navigation chart.
Conversion tables
Computed from definitions — 25.4 mm to the inch — and not copied from anywhere, so every row can be checked by anyone holding the book.
Pen test leaf
The last page, printed for it on purpose. Every notebook is used this way; printing it deliberately is cheaper than losing the last leaf to it by accident.

The film

Page by page

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

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