My wife is 5'4" and about 140, and I am putting a rifle together for her now. She loves the feel of my other manners EH-1 stocks, so I had one built with a 12.5" LOP that perfectly fits her, and will have a 20" barrel, and ready to hunt will be about 8.5 lbs, and short and handy for her, and chambered in 7 Sherman Max, and since she doesn't mind muzzle brakes, will have an efficient brake to mitigate any recoil and make it nice to shoot.
With females, keep in mind the generally have longer necks, higher cheek bones, and shorter LOP, and prefer a little lighter guns when compared to a guy, even of the same physical size. Recoil can also be an issue if they are not experienced with firearms and recoil management. They need a higher cheek rest than a same sized male does. If you don't want to spend the money of a custom, look at what BNG said, the Weatherby is a great option if it feels good to her. If you build one though, pay special attention to the level of the cheek and drop at comb, possibly talk to the stock maker of your choice prior to ordering. Also, keep in mind the size of objective scope you will use, the larger the scope the higher it will set, and the higher you will need the cheek to be, possibly even consider an adjustable cheek rest.
Things I have found from building for a VERY particular woman. I literally had to call Manners, and tell them specifically the pattern that she wanted the camo of her choice sponged on the stock. When I took the stock out of the wrapping and showed it to her, I was holding my breath hoping it was right for her ha ha.
