Four millimetres is a tight pitch for a square grid, tight enough to hold a dense diagram or a small table without the lines crowding each other into a blur. Thirty-eight rows fit the page at that spacing.
A coarser five millimetre version of the identical grid sits elsewhere on this shelf, better suited to a looser hand or a rougher sketch. Neither pitch is the correct one. It is a question of how small the drawing needs to sit.
Every square on the page is built from vector paths, not a tiled bitmap, so it keeps a sharp edge at any zoom instead of turning into a grey smear on a close look. It does not make the drawing inside the squares any more accurate.

Questions
How fine is the grid?
Four millimetres, thirty-eight rows to the page.
Is a coarser grid available?
Yes, a five millimetre version sits elsewhere on this shelf.
Is the grid a printed pattern or drawn geometry?
Vector geometry, not a tiled image, so it holds a sharp edge under a close zoom.
Is it dated?
No.
Does it come with a cover?
No. It is the sewn block, sized for a leather cover made separately.
A simple shadow is one where no light at all interferes with it.
