Ella's Pocket Diapers are available in 4 sizes:

Small fits approximately 7-13 lbs
Medium: 12-20 lbs
Large: 16-25 lbs
Extra Large: 25-35 lbs

Ella's sizing is somewhat different in range than other pocket diapers, so please be sure to check our weight range before choosing a size for your baby. For example only: A Medium Fuzzi Bunz pocket diaper is listed to fit up to 25 lbs, whereas an Ella's Medium only fits up to approx. 20 lbs. So, if your baby usually wears a Medium Fuzzi Bunz, she may need a Large Ella's.
