Bow length is a personal thing. I draw 29 inches, and struggle with anything under 60 inches long.
Bows are kind of like pick-up trucks, if you don`t like it, it`s always gonna give you trouble.
If you can get a few different bows in your paws to try that will help you make a decision.
At 5'4" tall I bet you are hard to tip over, and I bet you will shoot a 52" bow just fine.
Get those Zwickeys sharp, and keep your shots close.
In "05" there was a tall, wide, heavy beamed, Michigan eight point, that was very lucky my bow was sixty inches, instead of 52, cause my lower limb
came into contact with a tree limb, just enough to send my arrow low and right.
I hope your facination never ends.
Get started... there is so much to learn. Before you know it the summer will be gone, and a cool breeze will hit the back of your neck, and that facination will become an obsession.
Welcome, and as someone else said, keep it fun.
It only gets better.
