A quick and easy way (not technically the right way, but close enough) to check stock fit is to have her grip the pistol grip normally and point the gun straight up while bending her arm 90 degrees at the elbow. The stock should be the same length as her forearm and just fit in the crook of her arm.
I just went through this with my son and decided on a 10-22 with a collapsible stock. It can grow with him and I'm not too concerned about it being an auto loader since I hover over him anyway and could instantly take control if I had to.
To a much greater extent than most mechanical devices, firearms are terribly unforgiving of any overconfidence, complacency or negligence.
