Four millimetres is a tight pitch for a dot grid, tight enough to rule a small sketch or a dense bullet list without the dots crowding into each other. Thirty-eight rows fit the page at that spacing. The same grid at A5 size runs to forty-six; the sheet is smaller, not the dot. Every dot is a piece of vector geometry rather than a tiled image. It stays a sharp point at any zoom, instead of softening into a grey fleck the way a scanned dot grid does.

A five millimetre version of this same grid sits elsewhere on this shelf, coarser and better suited to a looser hand. Four millimetres is the finer of the two, built for anyone whose bullet journal habit runs toward small boxes and dense pages rather than open ones. Neither pitch is more correct than the other. It is a question of how small you write.

A dense page like this rewards patience more than speed. Filling thirty-eight rows with anything worth keeping takes longer than the eye expects the first time it sees how small the grid actually is.

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

Questions

How fine is the grid?

Four millimetres between dots, thirty-eight rows to the page.

Is the dot grid printed as an image?

No, it is vector geometry, so it stays a sharp point rather than a soft grey fleck under close inspection.

How does this compare to the A5 dotted notebook on the same grid?

Same four millimetre pitch, thirty-eight lines here against forty-six there. The smaller sheet holds fewer rows, not a coarser dot.

Is there a five millimetre option?

Yes, elsewhere on this shelf, coarser and suited to a looser hand.

Does it come with a cover?

No. It is the sewn block, sized for a leather cover made separately.

Remember that all is but opinion, and all opinion depends of the mind.
