The watermark on those makes this incredibly distasteful
I stashed away a whole lot of (expensive) graph paper. Never used it and now never will. I can easily do a log-log plot or log-lin plot on a spreadsheet. I think I even have some polar paper. I can see the point for cricket scoring paper as a way of capturing information, but for processing information, a computer is just too darn easy.
I was really expecting this to be a joke site that printed blank pages
ISO paper size?
For people who want to make their own: a lot of these are very easy to create in LaTeX. I made a bunch of templates a few years ago (https://michaelgoerz.net/notes/printable-paper-with-latex-an...) that I still regularly use in GoodNotes on the iPad.
