How to Find the Right Diaper Size for Your Baby
Finding the right diaper size is simple when you know your baby’s weight. Our chart shows Huggies® sizes from Preemie through Size 8 and helps you choose the best fit for your baby. Not sure of your baby’s exact weight? Here’s how to get your baby’s weight. Start by stepping on a scale alone, then again while holding your baby; now take the weight of you on the scale holding your baby and subtract your own weight from that. The difference is your baby’s weight. Once you know it, use the chart to see the recommended size and get an idea of how many diapers your little one may need each day.

Up to 10 lbs. | 8 per day | 1 month |

Tips for Using the Chart:
- Weight ranges: The chart matches diaper sizes to weight ranges, ensuring a comfortable, secure fit. For example, a Size 1 diaper typically fits babies 8–14 lbs., Size 2 fits 12–18 lbs., Size 4 fits 22–37 lbs., and Size 5 is for babies over 27 lbs.
- Diapers per day: Daily usage varies depending on your baby’s age, growth, and activity.
- Duration in each size: These are general estimates. Monitor your baby’s fit regularly, as growth rates differ.
- Diaper types: The chart covers all Huggies® options, from everyday diapers to specialty styles.
- Overlap: Some sizes overlap. Check fit to know when to move up a size.
This chart gives a clear overview of sizes and weight ranges so you can select the right diaper for every stage.
Huggies® Little Swimmers® Size Chart
Unlike ordinary diapers that swell in water, Little Swimmers® have a comfortable swimwear-like fit.
- Size 3: 16–26 lbs.
- Size 4: 24–34 lbs.
- Size 5/6: 32 lbs. and up.
With Easy Open Sides and a core that doesn’t swell in water, these swim diapers are designed for water play and made for comfort. Double Leak Guards fit snugly around your baby’s legs to help contain messes, so your little one can focus on having fun in the water.
Preemie & Newborn Diapers
When your baby arrives, the right diaper helps keep them comfortable, dry, and protected.
Preemie Diapers (Preemie Size)
If your baby is born smaller, Huggies® offers preemie diapers to provide a snug and secure fit while helping protect against leaks.
Newborn Diapers (Size N)
Newborn diapers are specially designed for babies weighing up to 10 pounds. Huggies® Little Snugglers® include a front cutout to protect the umbilical cord while it heals in the first few weeks.
Newborns go through a lot of diapers, so it’s a good idea to have a supply ready.
As your baby grows, keeping an eye on their weight and the fit of the diaper (is it getting too tight?) can help you know when it’s time to move from a newborn diaper to Size 1. Many babies outgrow newborn diapers within the first month or two, but every baby grows at their own pace.
Tip: For more guidance on umbilical cord care or planning your newborn diaper supply, explore Huggies® resources to help you get started and prepare for your baby’s arrival.

Preemie & Newborn Diapers

When to Size Up Diapers
Signs it may be time to move up a size include:
- The diaper no longer fits snugly below the belly button.
- You cannot fit two fingers comfortably under the waistband.
- The diaper leaves red marks on your baby’s tummy, thighs, or waist.
- The diaper doesn’t fully cover your baby’s bottom.
- There is an increase in leaks, blowouts, or diaper rash.
- Your baby shows discomfort or pulls at the diaper, which can indicate it’s too tight.
Paying attention to these cues can ensure a snug, comfortable fit and help protect from leaks.
How Should a Diaper Fit?
Every baby is unique, so proper fit depends on both weight and body shape. Huggies® uses weight ranges to guide diaper sizing:
Fit snuggly below the belly button

Cover the baby’s bottom completely
Fit snuggly around the legs. Not too tight
Two-finger gap between diaper & skin
Red marks may indicate the diaper is too small
Every baby is unique, so proper fit depends on both weight and body shape. Huggies® uses weight ranges to guide diaper sizing, not age, because it’s the most reliable way to ensure comfort and protection.
- Fit snuggly below the belly button: The waistband should sit just under your baby’s tummy.
- Cover the baby’s bottom completely: Ensure there is full coverage to help protect against leaks.
- Fit snuggly around the legs without being too tight: Run your finger along the leg cuffs to create a comfortable barrier that helps protect against blowouts.
- Maintain a two-finger gap between the diaper and skin: This can ensure the diaper is snug but not restrictive.
- Avoid red marks: Check your baby after each diaper change; red marks can indicate the diaper may be too small.
- Remember, This is a general guide: some babies may need to size down for a snug fit, while others may need to size up sooner. Monitoring fit regularly helps keep your baby comfortable and protected from leaks.
