How To Tell If Diaper Is Too Big [2023]

Buying diapers based on the supplier's guided weight range might be too big and cause discomfort and affect overall well-being.

According to Dr. Brandon Smith, Assistant Professor of Pediatrics in the Department of Pediatrics at Johns Hopkins said, while properly fitting diapers shouldn’t cause any issues, there are telltale signs that a diaper isn’t fitting correctly. “Irritation on the child’s skin, leakage or a portion of the baby’s bottom being exposed in the back are all signs a child may need a different diaper size.”

Here are some indicators that the diaper might be too large:

1. Fit around the legs: Check if there are gaps or spaces between the diaper and the thighs. If the leg openings are too loose and there is significant space, it may indicate that the diaper is too big.

2. Sagging: If the diaper sags excessively around your baby's waist or bottom, it could be a sign that it is too big. The weight of a wet diaper may cause it to sag, but if it appears excessively loose even when dry, it might be too large.

3. Leaks and blowouts: If you notice frequent leaks or blowouts, especially around the leg openings or back, it might suggest that the diaper is not fitting snugly. This could be an indication of a size issue.

4. Red marks or chafing: Check your baby's skin for red spots or chafing around the waist or leg area. If the diaper is too tight, it may leave marks, while a loose diaper can rub against the skin and cause irritation.

Proper diaper fit is crucial for your baby's comfort and protection. A well-fitted diaper ensures fewer leaks and promotes a happier baby. 

Reasons that Diaper Does Not Fit

I learned from another parent about the consequences of not paying attention to diaper fit, and sometimes diaper leaks before it is full due to poor diaper fit.

“All diapers sizes and fits can be a little bit different, making things slightly confusing at first or if you’re switching brands,” notes Dr. Jen Trachtenberg, a board-certified pediatrician in New York City.

The diaper does not fit even though you buy based on the guided weight range because

• Baby's body shape: Every baby is unique, and their body shape can vary. While weight is a general guideline for choosing diaper sizes, some babies may have different proportions. For example, a baby with chubby thighs might require a larger size to accommodate their leg circumference, even if their overall weight is within the recommended range.
• Brand and style differences: Diapers from different brands can have variations in their sizing and design. Some brands might have a more generous fit, while others may run smaller. Additionally, different diaper styles, such as those with stretchy sides or elastic waistbands, can affect the fit. It's essential to try different brands and styles to find the one that suits your baby's body shape and provides the best fit.
• Diaper absorbency: Diaper sizes are often based on weight guidelines, but babies' needs for absorbency can differ. If your baby is a heavy wetter, it may require a larger size to accommodate more liquid without causing leaks.
• Growth spurts: Babies grow rapidly, and their body proportions can change during growth spurts. A diaper size that previously fit well may suddenly start to feel tight or uncomfortable. In such cases, it's advisable to reassess the fit and consider moving up to the next size.

If you find that a diaper size isn't fitting correctly despite the weight being within the recommended range, consider trying the next size up or experimenting with different brands or styles. Diapering is more than just a daily routine; it's an opportunity to bond with your baby. Understanding the signs of an ill-fitting diaper ensures a comfortable experience for both of you.
