LEGEND
Weight - The weight range from and to FuzziBunz® will fit
Average Build - Babies within the "average" range of the growth chart
Larger Build - Babies who fall in the 80+ percentile on the growth chart
Baby's Age - On average, what age range of baby each size FuzziBunz® will fit
Thigh - Approximate thigh measurements that each size FuzziBunz® will fit
Rise - The length of the diaper from front waist to back waist

MEASURING YOUR BABY

To measure your baby's thighs: Measure where the elastic of a diaper would normally be - around the meatiest part of the baby's thigh.

To measure your baby's rise: Measure from mid-back at the waistline to slightly below his belly where his/her diaper normally would come up to.

*Please note: These measurements take into consideration only one insert in the FuzziBunz® at a time. Always try your new FuzziBunz® on your baby with an insert for size before washing / using.

If the size chart is still baffling you...

Here is some additional information for you to use in trying to choose the best size for your baby:

  • XS FuzziBunz® are for either preemie or very small babies - they will fit newborns very well, however, not for a very long time.

  • Small FuzziBunz® will fit babies that are newborn (although they may be a tad big at first) through about 6 or 8 months of age when they are ready for the mediums.

  • Medium FuzziBunz® will fit babies with either small or large thighs. Medium is our most popular size because babies stay in this size the longest! They will fit babies from about 4 months old (depending on their growth rate and size build) up to potty training stages.

  • Large FuzziBunz® will generally not start fitting your baby until at the very least, 12 months old or are in the weight range or very tall.

  • Petite, Toddler and XL are specialty sizes. Mediums have been found from our size testing to fit better and for longer periods than the Petite size diaper for skinny toddlers. XL can be used for older potty training children or other circumstances where larger diaper is needed.

Disclaimer: Our Size Chart has recently been updated to reflect more up to date size data. FuzziBunz® diapers have NOT changed their sizes - only the size chart.
