Quick Answer
Choose Pampers Baby Dry Size 4+ if your baby weighs between 9kg and 20kg for a longer fit window. Opt for Size 4 if your baby is under 14kg and you prefer more nappies per pack.
Why Size 4+ Extends the Fit Window
Pampers Baby Dry Size 4 covers babies from 9kg to 14kg, while Size 4+ stretches from 9kg up to 20kg. This extra range means Size 4+ can accommodate growth spurts without needing to size up as quickly. For parents who want a single size to last longer, Size 4+ offers more flexibility.
Quantity Trade-Off: More Nappies vs Longer Fit
Size 4 comes in a case of 84 nappies, whereas Size 4+ contains 76 nappies per pack. If your baby is comfortably within the 9kg–14kg range, Size 4 gives you more nappies for your money. If your baby is heavier or growing fast, the slightly smaller pack of Size 4+ may be worth the extended fit.
How Size 3 and Size 5 Fit Into the Picture
Pampers Baby Dry Size 3 is designed for babies 6kg–10kg, making it a good option before your baby reaches 9kg. Once your baby outgrows Size 4+, Pampers Baby Dry Nappy Pants Size 5 (sold as Pampers Easy Ups) provides a pull-on style for active toddlers. Both sizes are worth considering as your baby moves through the weight ranges.
Trade-Offs at a Glance
- Size 4 (9kg–14kg, 84 nappies): Best for babies who are solidly in the 9–14 kg range and not growing rapidly. You get more nappies per pack, which can save money and reduce packaging waste. Check your baby's current weight and growth trajectory before choosing.
- Size 4+ (9kg–20kg, 76 nappies): Ideal for babies who are nearing 14 kg or growing quickly. The extended weight range means you may not need to size up as soon, but you get fewer nappies per pack. If your baby is between 14–20 kg, Size 4+ is the only choice in this comparison.
- Size 3 (6kg–10kg, 98 nappies): A good stepping stone before Size 4. If your baby is under 9 kg, Size 3 offers more nappies and a snugger fit. Consider Size 3 if your baby is under 9 kg to avoid a loose fit.
