Dear Isaiah Six3,
Let me give you my humble opinion, if you will. I believe a Bible is an immensely personal possession. One which the user is best to pick out. If you are financially gifted with the means, perhaps you could buy several and let her select the one she prefers and then return the others (or, gift them to an organization that would distribute them to those who can not afford one of their own.) I have 4 main Bibles and duplicates of some of those. The one I hold and read most often is a medium size print KJV I bought at a yard sale for $1. It has soft leather-like covers and it feels comfortable to hold. Before I found that one (Actually, I should say before God gave me that one.) we bought a large print KJV that is like the big brother to that one. It is very easy to read but the size is not as comfortable to hold when I do my nightly bedtime reading. The other ones had hard covers and they are heavy, after a short while this tends to make old hands painful.
Does she want a home Bible, or a carry along Bible? I have two small 'palm of your hand' sized ones I carry in my purse. One has been through a hard life and if difficult to read (but still usable), the other has sharper to read print, soft leather like covers and best of all Psalms and Proverbs included.
Maybe you could take her to a Public Library and go through the ones they have (They do still have them, don't they?? Praise the Lord!). Or, check with a local Church and see if any of them have a library she could browse.
A personal Bible is something that becomes a part of yourself, it is good to have the luxury of getting the proper fit.
