Four millimetres, corner to corner: that is the specification, and on a page sold for its ruling it is the only fact worth arguing about. Forty-six rows fit the column at that pitch, run the same distance apart from the first page to the last, with no divider or index interrupting the count.
The dot is drawn, not tiled. A grid built from a repeated bitmap goes soft at the edges the moment somebody zooms into a scan or a print run enlarges it past its own resolution; a grid built from vector lines does not, because there is no fixed resolution to run out of. Most listings for a dotted page stop at the words 'dot grid' and leave the spacing to arrive with the parcel.
This one states it up front: 4.0 millimetres, one hundred thirty-two ruled pages, plain. Nothing on the page explains what the grid is for. That was never this book's job.

Questions
What is the exact dot spacing?
4.0 millimetres, measured centre to centre.
How many rows fit a page?
Forty-six, at that pitch.
How big is it?
A5, 148 x 210 mm, 140 pages, 8.01 mm across the spine.
Is the grid printed as a bitmap image?
No. Every dot is a drawn point in the page's own geometry, so it stays sharp at any zoom rather than softening like a tiled scan.
Is it dated?
No.
Nothing must be thought to belong to a man, which doth not belong unto him as he is a man.
