The Quick Answer: The Classic Diaper Size Chart
Whether it's Pampers, babylove, Hipp, or Lillydoo – most manufacturers follow a very similar standard. Here is the quick overview you can use as a guide when shopping:
- Size 1 (Newborn): 2 to 5 kg
- Size 2 (Mini): 4 to 8 kg
- Size 3 (Midi): 6 to 10 kg
- Size 4 (Maxi): 9 to 14 kg
- Size 5 (Junior): 11 to 16 kg
- Size 6 (XL): 13 to 18 kg+
When should you switch to the next size?
The weight indicated on the package is always just a guideline. Every baby has a different build – some are long and slim, others have adorable chubby legs. You can tell in everyday life that it's time for an upgrade by these signs:
- The diaper leaks at night: The absorbent material has reached its limit. If the bodysuit is wet in the morning, going up a size often works wonders immediately!
- Red marks: If the cuffs around the thighs or stomach leave red marks after changing, the current diaper is too tight.
- The fastening tabs are tight: The adhesive strips should comfortably close in the middle of the belly. If they stick all the way out on the edge, the diaper is too small.
What do the intermediate sizes (e.g., size 4+ or 5+) mean?
Sometimes you'll see a "+" after the size on the drugstore shelf. Important to know: These diapers are not larger in cut than the normal number! They simply contain more absorbent material. They are perfect for nighttime when your baby drinks a lot but doesn't yet fit into the next "real" size.
Conclusion: Better to switch sooner than later
Midwives often advise: If your baby is right between two sizes (e.g., at 9 kg), opt for the larger variant. It catches more liquid, doesn't pinch, and is much more comfortable for your baby.
