What size board should I get? Custom made.

[Kooks]

I am 15 and a male, I weigh just under 100lb. I am 5'3 and have been surfing for over a year. I am working on the basic maneuvers, like cutbacks, snaps and floaters. The beach that I surf is on average a 3ft to 5ft wave. It is a beach break called Playa Venao in Panama. I surf from 1-3 times a week. I am surfing on a Byrne MB 15 High Performance board the dimensions are 5'8 18.37 2.12 230x215007-1. Sorry if that is wrong cant read it very well. I am trying to get a board custom made for me. This board is a little fatter than I want. I was thinking between a 5'4 and 5'6. I just don't know how wide and how fat I should get it. Thanks

In the next year or so you will get heavier quickly, and your new smaller board may end up being a waste of money.
