Go to a bike shop and get fitted; see what size you are.

In Trek road bikes, you’d probably need a 44 cm frame. The nice thing about this is that you can probably get a second hand bike cheap. It’s a size that maybe a growing kid would have.

My 11 year old daughter would ride that size; she’s 4’11”. Maybe find one on the net and have it shipped to your local shop.
