Hibrkraft's Plain Lab

Books that state their own measurements.

Plain Lab is Hibrkraft's printed-book line: agendas, planners, journals, notebooks and logbooks. Sewn in signatures at the same bindery as our leather journals, in Bogor.

Five Plain Lab books on a wooden desk beside a window. Security Patrol Book 2027, Maintenance Calendar 2027 and Dotted Notebook 4 mm stand against the wall; Daily Agenda 2027 lies across Site Diary 2027. To the right an open dotted notebook carries a handwritten list for the day, with a pen resting on it.

Not sure where to start?

Six questions and you may skip any of them. What it is for, what you do, how big, how close a ruling, whether it needs dates, how thick.

Almost no notebook seller states its ruling pitch. They write "lined" or "dotted" and stop there, so the only way to find out whether your handwriting fits is to buy one first.

These books come off an engine that knows its own geometry, so every product page states the figures: the pitch in millimetres and points, how many rows that yields at this trim, the signature count, and the spine thickness. The same numbers are printed on the last leaf of the book itself.

One ruling gives different line counts at different sizes. College ruling at 7.14 mm gives 24 lines on A5 and 21 on 5 × 7 inches. That is not a small detail if you write by hand every day.

The numbers

One ruling, two sizes, two line counts.

This is the thing no seller states, and the only thing you can check yourself once the book arrives.

Ruling	A5 · 148 × 210 mm	5 × 7 in · 127 × 178 mm
lined · 7.14 mm	24	21
lined · 6.00 mm	30	25
dot · 5.00 mm	36	30

Same pitch, smaller page. Not a rounding — computed from each book's own geometry and printed on its last leaf.

Browse by ruling pitch

8 pitch pages. Each states how many rows you get on A5 and on 5 × 7 — measured, not nominal.

Every swatch is drawn at its true pitch, in a window of the same height. The scale is exact relative to the others; against a ruler held to your screen, approximate.

Each page states how many books fall inside it, and from which shelves.

A vertical film, 13 seconds: the ruling page and the figures printed on its last leaf. Synthesised ambient bed, no dialogue — captions in three languages.

The table above, moving: two trims drawn at one scale, so the gap between the rules is the same on screen because it is the same on paper.
