What Size Clothes Do Premature Babies Wear?
When you have a premature baby, everything feels new and unexpected including buying clothes. While you may have stocked up on newborn outfits during pregnancy, preemie babies are often too small to fit into them. That leaves many parents wondering: what size clothes do premature babies wear?
In this article, we’ll break it down in a simple way. Whether your baby is in the NICU or coming home soon, understanding preemie clothing sizes will help you feel more confident and prepared.
Understanding Preemie Sizes
Most baby clothing starts at “newborn” size, but that usually fits babies who are around 7–9 pounds (3.2–4.1 kg). Premature babies are often born weighing less than 5 pounds, so newborn clothes tend to be too big.
This is where special preemie sizes come in. These clothes are made smaller to fit tinier babies comfortably and safely. Many brands offer multiple preemie size ranges, which is helpful because not all premature babies are the same size.
Here’s a general guide:
| Label | Weight Range | Length Range |
|---|---|---|
| Micro Preemie | Under 3 lbs (1.36 kg) | Under 15 inches (38 cm) |
| Small Preemie | 3–5 lbs (1.36–2.27 kg) | 15–17 inches (38–43 cm) |
| Preemie | 5–6 lbs (2.27–2.72 kg) | 17–18 inches (43–46 cm) |
| Newborn | 6–9 lbs (2.72–4.08 kg) | 18–21 inches (46–53 cm) |
Keep in mind that sizes vary slightly between brands, but this chart gives you a good place to start.
How to Know What Size to Buy
The best way to choose clothing size is to go by your baby’s weight and length, not just their age. Premature babies can spend days or weeks in the hospital growing and gaining weight. Doctors or nurses can usually tell you your baby’s current size and when they might be ready to move up in clothing size.
It’s also a good idea to check labels carefully. Some clothes might just say “Preemie,” while others might include the exact weight or length the item is designed for. If you’re shopping online, most product pages will list the measurements.
Special Features to Look For
Besides size, there are a few other things to keep in mind when choosing clothes for a premature baby:
- Soft fabrics – Look for 100% cotton or organic materials that are gentle on sensitive skin.
- Easy access – Babies in the NICU may need wires, tubes, or monitors. Clothes with side snaps, front openings, or wrap styles make dressing easier.
- No tags or rough seams – Avoid anything that might rub or irritate their skin.
- Machine washable – You’ll be doing laundry often, so choose items that are easy to clean and hold up well.
Some brands even make clothes labeled “NICU-Friendly,” designed specifically with hospital care in mind.
How Many Outfits Do You Need?
Start small. Your baby will grow quickly, and you may not need many items in each size. Here’s a basic list:
- 4–6 onesies or bodysuits
- 3–5 sleepers or gowns
- 2–3 hats
- 1–2 soft blankets
- A few pairs of socks or booties
If your baby is staying in the NICU, you might not need much at first. The hospital may provide clothes until your baby is ready to go home. Once your baby is home, you’ll want to have enough clothes to get through a few days without constant laundry.
Where to Find Preemie Clothes
Not every store carries preemie sizes in-store, but you can find a wide range online. Some popular places that offer Premature Baby Clothes include:
- Carter’s
- Gerber
- Target
- Walmart
- Amazon
- Etsy (for handmade or customized pieces)
Look for trusted brands and read reviews to make sure you’re getting good-quality items that are true to size.
Final Thoughts
Buying clothes for your premature baby can feel overwhelming at first. But once you understand the sizing and what to look for, it becomes much easier. Focus on comfort, fit, and softness. Don’t worry about fancy outfits your baby just needs to be cozy and safe as they grow stronger.
And remember, all babies grow at their own pace. Soon enough, your little one will be fitting into newborn and then 0–3 month sizes before you know it. Until then, preemie sizes are a great way to help your baby feel warm, loved, and snug in their tiny clothes.
