How much bigger were invertebrates during the Carboniferous (on average)?

I tried asking this question in r/askscience, but after a day with no responses, it appears to have disappeared. I thought I'd take a shot asking here, because this seems like the sub that would have an answer.

Many people know about how invertebrates were larger during the carboniferous due to higher oxygen levels. At 35% atmospheric oxygen, we got creatures like Arthropleura and Meganeura. Were these the biggest that invertebrates could get during that time, or could there be larger ones that we just haven't found yet? Is there some equation that can calculate how large an invertebrate can get with a given value of atmospheric oxygen?

Also, as a side question (and probably straying from r/entomology's area of expertise, but it was part of my original question), how are/were vertebrates affected by different oxygen levels? Were they also larger during the Carboniferous?
