What Size Litter Box For Kitten?

I have a 10 1/2 pound kitten who is only 1 month old. She has been using an aluminum pan with a litter bag since she was 5 weeks. The bag fills up quickly and the box won’t stay full for very long. The last few times I changed her litter box, it didn’t make any difference in how much the box contained. So what size litter tray do you think would work best? Thanks!
