Frequently Asked Questions

The Pampers Diaper Purchase Planner is a helpful tool designed to make diaper planning easier. Simply select your baby’s current diaper size and how long they've been in that size. The tool will then estimate how many more diapers your baby might need before moving up to the next size. It’s a handy way to plan ahead, stock up smartly, and avoid last-minute diaper runs. Note: This is a one-month estimation and may vary depending on your baby’s growth and diapering needs.
The easiest way to choose a diaper size is to match your baby's weight to the recommendations on the Pampers size chart. Since every baby grows differently, checking the fit regularly matters just as much as the number on the scale. If you're unsure, our diaper size and weight chart is a great place to start. You can also download the Pampers Rewards app to save on all those perfectly fitted diapers.
A diaper should fit snug—but not too tight—around your baby’s waist and thighs. You should be able to slide two fingers under the waistband comfortably, and the leg cuffs shouldn’t leave red marks or gaps.
Pampers diaper sizesare based on your baby’s weight, not their age, so the best way to ensure a good fit is to use our diaper size chart by weight. If the diaper feels tight or you’re seeing red marks or leaks, it might be time to switch sizes.
