Diapers Size Guide

The chart below serves as an excellent reference for selecting the right
diaper size for your baby based on their weight and developmental
stage. However, it’s important to watch for signs of a poor fit once the
diaper is on. Indicators such as frequent leaks, red marks on your
baby’s skin, or gaps suggest the diaper doesn’t fit properly. If your
baby is approaching the upper limit of the weight range, it might be
time to switch to a larger size.

Size 3 16-28 lbs
Size 4 22-37 lbs

Tips for choosing the right diaper size


With numerous diaper changes ahead, ensuring a proper fit is crucial. Here are five tips to help you select the right diaper for your baby:

  Check for Red Marks: If you notice red marks on your baby’s skin, the diaper might be too tight, or your baby could be experiencing diaper rash, which occurs when the diaper area is frequently exposed to urine and stool.

  Monitor for Leaks: While occasional leaks are normal, consistent leaking may indicate that the diaper doesn’t fit properly.

  Assess the Waist Fit: The diaper should close easily without needing to pull hard on the tabs. Tabs should be fastened straight across and at the same height in both the front and back. Ensure the diaper isn’t too tight, especially at night.

  Check the Rise: The diaper’s rise should be around your baby’s belly button. If it appears low, it’s time to move up a size.

  Consider Absorbency: A more absorbent diaper will do a better job of keeping your baby’s skin dry.
