I disagree that the seat tube length sizing on mountain bikes is variable. The actual length may vary but a 19” (or 16”) mountain bike is still going to have the same reach as any other 19” mountain bike. That’s where. Someone going from a 16” mountain bike to a 19” mountain bike is going to have trouble with reaching the bars.

A 19” road bike is 49cm, by the way but the proportions are very different.
