Each square in this ruling is cut twice: once by the solid outline that fixes its edge, and once by a dashed cross running through the centre, both ways. A character written inside the square has something to measure its own proportion against, rather than a blank box where the middle is wherever the hand decides it is.

The square is 14.01 millimetres, twelve rows to a page. A how-to-use page explains the two kinds of line, solid and dashed, before the first ruled page arrives, and one hundred and nine pages of the grid follow it. A short run of plain lined pages closes the book, for a translation or a note that does not belong inside a square.

The cross does not know if the character is correct. It only gives the stroke a centre to be measured against, which is a different thing from being right.
