If it is a 150 it could work. I think a 152 would be a tad on the big side for her especially if she is just learning. It also depends on conditions, if she is just going to ride pow a larger board would work. We are about the same size, but I am a tad bit smaller but I ride a 147. Also she is new to the sport, her view of the park might change once she really gets into it. If it is a great deal though
Basicly, it could work but depending on conditions and what she wants to do with it.
