"Way too grainy?" Is this based on experience or just some thought that 400 film must be?

I shoot Portra 400 in 35mm. It's plenty fine grained enough for me, really superb film. If you're printing, say, 16x20 from 35mm then it might be worth going to 160, but up to 11x14 I think Portra 400 is a great film.
