How do I make my Sims character tiles bigger when having more then 8 Sims?

I have my one main save file in the sims, I used MC Command center to make it so that I can have more then 8 people in a household. It works great but the only problem is that the little tiles with all the sims have gotten smaller. Is there anyway I can adjust them so that they are bigger and easier to click on?

(I don't know what the character tiles proper name is, but I hope somebody knows what I'm talking about.)
