Picking the Right Pampers Diaper Size for Your Little One
To find a diaper size for your little one, use our diaper size finder below, adding your baby’s weight to come up with the best Pampers diaper size for your baby.
The guide will also provide an average number of diapers you can expect to use and will let you know about how many months your little one will need this size. It’s a great tool for planning ahead!
Read on to find out more about how you can check whether your baby’s diaper fits perfectly, when to switch to a bigger diaper size, and which Pampers diaper is best for your little one—from newborn diaper sizes and beyond. Plus, pick up some tips on how to help prevent leaks and blowouts.
Making Sure the Diaper Fits Right
As you know, babies come in all sizes and shapes, so diapers fit a bit differently on every baby. To keep things simpler, Pampers diapers sizes are based on baby weight—not things like age or gender.
Most of the time, your baby's weight will fall neatly within the range of a certain diaper size, producing a good fit. In some cases, you might have a choice of two sizes, as the weight ranges can sometimes overlap.
If you have a baby who is long and slim, for example, you might need to go with the smaller of the two sizes for the best fit.
Beyond checking to make sure the diaper suits your baby’s weight, there are four quick checks you can do to make sure your baby’s diaper fits properly:
The diaper’s waistband should sit just under your baby’s belly button.
The leg cuffs shouldn’t have any gaps. After the diaper is on, run two fingers just inside the leg cuffs to get them in the proper position to help prevent leaks.
After the diaper is fastened, you should be able to fit two fingers under the waistband. This means the diaper is fitted properly — not too snug, not too loose.
When you take the diaper off, you shouldn’t see any red marks.
How to Weigh Your Baby
To weigh your baby, you can use your normal bathroom scale. Take off your baby’s clothes and diaper, and then step on the scale while holding her. Record the number. Then, step back on the scale without your baby. Subtract the second number from the first number to get your baby’s weight.
When to Change Diaper Sizes
Some signs your baby might be ready for a different size diaper:
If the fastening tapes don't reach the center of the waistband, it's time for a bigger size; if the tapes overlap, the diaper may be too big.
If you can't comfortably fit two fingers under the waistband of the fastened diaper, it's time for a bigger size.
You may need to go up a size if you notice red marks on your baby's tummy or thighs when you remove the diaper.
If the diaper isn't fully covering your baby's bottom, choose a bigger size.
If your baby regularly gets diaper rash it may be because her diapers are too small and don't hold the moisture away from the skin.
The diaper may be too small if your baby is showing signs of discomfort (for example, pulling at the diaper).
Which Pampers Diaper Is Best for My Baby?
As your baby grows, he'll have different diaper needs. Here are some things to consider when choosing which Pampers diaper to buy:
Newborns have very delicate skin, so choose a diaper that's:
super absorbent to keep your baby's skin dry
designed so it doesn't rub against the umbilical cord stump
easy to put on and fasten.
When your little one is wiggling a lot, crawling, or beginning to walk, consider diapers that are easier to take off quickly. For example, you might like Pampers Cruisers 360° Fit or Pampers Easy Ups.
This chart summarizes the sizes that each Pampers diaper is available in to help you select the right one:
Why Do Leaks and Blowouts Happen?
If a diaper is too small, it can leak because there isn’t enough absorbency for the volume of pee or poop.
If the leg cuffs don’t fit properly or are tucked insider the diaper, pee can leak out the sides.
If a diaper is too big, urine and poop may leak out of the gaps before the diaper can absorb it.
How to Prevent Leaks and Blowouts
Do the following to help prevent diaper leaks and blowouts:
Check the diaper to make sure it looks straight and balanced on your baby.
Make sure the waistband sits just under your baby's belly button.
Make sure the tapes align with the colored waistband when they're fastened.
Run two fingers under the waistband so you're sure the diaper isn't too tight or too loose.
If you have a baby boy, check to make sure his penis is pointing down inside the diaper.
Pull the leg cuffs out by running your fingers around the leg cuff after the diaper is on.
If you've done all this and checked you've got the right diaper size, it could be time to choose a more absorbent diaper, like Pampers Baby-Dry or Pampers Swaddlers Overnights.
Once you find the best diaper size for your little one using either our diaper fit finder tool or our diaper size chart, selecting the right diaper will be a breeze. Your baby will be comfier, and you'll feel more confident knowing that your little one will have far fewer accidents with leaks or blowouts.
Still, just in case a leak and blowout happens, keep your diaper bag well stocked using our diaper bag checklist to make sure you're prepared for all situations.
