how could you use a utility bill or usage history (KWh), to determine service size?

This works if the utility provides demand information. In general, they do not for residential customers, but do for commercial/industrial. IF they provide, or you can get the demand information, its as easy as reading it off the bill, and converting the KW figure to amps. You are not even specifically required to account for lack of balance or power factor. 220.87 is my fav!

It sounds like they do not provide demand information. You could call them, perhaps they have the data but dont put it on the bill? Demand is different than average.. Demand is the highest load seen in a given interval, usually 15 minutes.
