Maximum Font Size

What is the maximum font size? Is there a way to increase the font size? I’ve been making a tiny package that creates figures at many different plot sizes. For the largest (33.1x46.8 inches), the fonts appear to be maxing out at around 128 or so.

Do you have a repro? A quick check suggests that for me font sizes up to 2048 work fine, I didn’t bother going further…

I’ve been working on a package to reproduce a different graph at many papersizes. I’ll have to figure out how to make a smaller example.
