I really want to learn how to play guitar... help me find the right size guitar!!!?

I'm about 5 foot 3 inches, and my arms are pretty long (in comparison to my height) sorry if that description was confusing! anyway I was looking at an acoustic guitar that is "short scale" at 23 1/4 inches. Is this too small? Because the description says it's for "smaller girls" As in little kids or smaller people in general. (I'm 15 if that matters) If you could give some suggestions for length or even about guitars in general for a beginner I would love to hear it! (just dumb it down because I know nothing about guitars. (For the record I can read music) Here is the link to the guitar I was looking at: a href="http://www.daisyrock.com/products/acoustic/jr-miss-acoustic/debutante-junior-miss-short-scale-acoustic-pack" rel="nofollow"http://www.daisyrock.com/products/acoust…/a
