For beyond botball, 40 mm. I assume it is the same.

Yup our team asked about this on the homebase, the official size is 40mm and 3-star quality. Which is interesting because the 38mm ones we had lying around fit in the tubes and rolled out quite nicely, but the 40mm ones get stuck pretty often.

I found two-star quality ones that are 40-mm for like $20. There were 48 balls in total. Much cheaper than buying them in six packs at the store. I can link the item if you want.

It varies slightly but I would say somewhere around 40 mm
