Wait a second
You are 5 feet-chances are your inseam is more like 26-27 than 29-30.
I suspect the 14.5" is correct.
How much stand over room do you have?
When you standover the top tube-how much room between it and your groin? Should be 2" or so on a bike like that-but 1" is OK maybe.
Hunt around for a seat post with a bit more setback- or a seat with more rail room
and a longer stem easy enough to find also.
15.5" with 29" wheels-standover is about 30"-guessing you would be very close to top tube when you stand over it.
A 16" 26" wheeled bike has a tope tube height about like a 29" 14.5"
Just dial it in with a different stem or seat post setback?
PS Your legs are pretty long for 5' tall-female??I'm 5'4" and a 820 trek 16" would be a little tall for me.
PPS I always felt more comfortable riding "too tall bikes" because the seat would have to be set lower relative to the bars-so it gave me a more upright posture-better view-easier on neck
