It's impossible to say with just the above information. Not only
that, but the "size" of a MTB is a very subjective thing -
manufacturers determine the size differently (center to top, center to
center, center to top of the seat tube), rendering the measurement
meaningless. Add in the fact that two bikes with the same "size"
might have wildly different "****pit lengths" (top tube plus stem
horizontal).
Chances are you're going to want to find a bike that's in the "size
above the smallest, but below the middle" for a guy who's 5'7". That
would translate to a 15" in my line (not that I'm recommending it,
probably not what he needs). For example, I measure frames center to
top (of the top tube), and they come in 13.5, 15, 17, 18.5, and 20"
sizes (with correspondingly sized top tubes).
Hope that helps,
