Everyone will argue my opinion on this topic and my article on the subject written almost 20 years ago still rings of truth. I'll share the highlights;
Keep in mind the size of the player's hand can be a determining factor. My original article was written with the train of thought being cost effective for families. Most players don't want to have more than 1 glove. I still say a 12" to 12.5" glove is a good utility sized glove. Very versatile in size for any position. Some may consider an 11" to 11.5" for infielders while a 13" to 14.5" for outfielders. A girl playing college ball may want 2 gloves in her bag. Many playing infield still want a 12" to 12.5" glove for reasons of argument that suit their opinion. That's okay, my summary will explain.
The best glove for your daughter is the one she likes. If she believes in it she'll perform at her peak. Having said this, gloves still need to be replaced due to wear. Once they lose their shape or begin to break down, it's time to break in a new one. Pro baseball players will have professionals breaking in new gloves for them throughout the season. They are almost always the same brand and model they are comfortable with. They play over 100 games plus practices in a season and will some times use 3-4 gloves a season. Some may hate to hear this but if a normally maintained glove starts having string failure, you may want to start getting another glove ready. I know things can happen to strings but the leather strings are telling you something about that leather glove. The message is subtle but still a message.
