How Diaper Sizes Work

A common question among parents is how to read a diaper size chart by age; however, age isn’t the ideal factor to consider. Instead, after taking hundreds of thousands of measurements, Lebrace has organized diaper size by weight to help you select the right diaper. As you’re looking at the diaper size comparison chart below, keep in mind that your little one’s weight will be the most important factor.

Diaper Size Guide: How to Get the Right Fit

Babies come in all sizes and shapes, so diapers fit a little differently on every child. Lebrace diaper sizes go by your baby’s weight—not age or gender—as weight is the most accurate way to determine the correct fit. Most of the time, your baby’s weight will fall neatly within the range of a certain diaper size, producing a good fit. But in some cases, you might need to choose between two sizes, as the weight ranges can overlap.

Once you’ve selected a diaper size by your baby’s weight, then try these four quick checks to ensure a proper fit:

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 remove any gaps, which can help prevent leaks.

After fastening the diaper, you should be able to fit two fingers under the waistband. This means the diaper fits correctly—not too snug, not too loose.

You shouldn’t see any red marks on your baby’s skin when you take the diaper

When to Size Up Diapers

Besides an increase in weight, there are additional signs that your baby might be ready for a larger diaper size. The following guidelines can help ensure your little one is wearing the correct diaper size:

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 rashes, it may be because the diaper is too small and doesn’t keep the moisture away from their skin.

The diaper may be too small if your baby shows signs of distress (for example, pulling at the diaper).

Which Lebrace Diaper Is Best for My Baby?

Diaper needs will change as your baby grows, becomes more active, and approaches different development milestone. Lebrace offers a full lineup of diapers to support your little one at every age and stage of development.

Here are some things to consider when choosing which Lebrace product to buy:

For Newborns

As newborns have very delicate skin (and need gentle materials and appropriate skincare), look for a diaper that’s

  • Very soft
  • 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.
