I've been trying to google/amazon this and having basically no results, so I'm asking here in case anyone knows:

I need graph paper. Specifically I need LARGE graph paper. Like, not an A4 sheet, I need A1-A0 (24/33" or 33x46").
4x4 per inch, or 5x5 per inch grid spaces. I basically need a graph paper with a TON of squares, and I'm not finding it.
