Can’t really answer the question based solely on square footage. You need a proper heat load calculation which takes in all kinds of factors including location, shade, overhangs, windows, heat producing appliances, etc.

I have 15yr old 1700 sq ft ranch with full size walkout basement with a 5ton unit and it will pretty much run all day when it’s real hot. That is a big unit and other houses my size may run 2.5-3t just fine. Just guessing I would say you will end up close to 4t.
