This is probably a quite stupid question but I'm having a brain fade at the moment How can one go about folding a square grid on a rectangle of paper? (without measuring)

Obviously with square paper you just keep halving the paper in both directions but in the case of rectangular paper that will give you a rectangular grid - I'm sure there must be a fairly simple geometric way to do it but my brain just isn't awake today

fold a diagonal of a square both ways, then crease the grid in that part only. then use the existing lines as a reference for folding the rest of the uncreased paper into a square grid.

see the second picture.
Then make a grid based on the square

yes - this is what i was going to do but for some reason i thought there was a 'better' way... but this is straightforward and simple really
