What Size Clothes Does a 3 Month Old Usually Wear?

Most babies around three months old wear 3–6 Months clothing. However, every baby grows at a different pace. Use the chart below as a general guideline.

Baby Age Clothing Size Average Weight Average Length
Newborn NB Up to 8 lbs (3.6 kg) Up to 21.5 in (54.5 cm)
0–3 Months 0–3M 8–12 lbs (3.6–5.4 kg) 21–24 in (53–61 cm)
3–6 Months 3–6M 12–16 lbs (5.4–7.3 kg) 24–26 in (61–66 cm)
6–9 Months 6–9M 16–20 lbs (7.3–9.1 kg) 26–28 in (66–71 cm)
9–12 Months 9–12M 20–24 lbs (9.1–10.9 kg) 28–30 in (71–76 cm)

Tip: Baby clothing sizes can vary between brands. Always check the manufacturer's size chart and choose the size based on your baby's height and weight rather than age alone.

Most babies reach the 3–6 month size by the time they are around three months old, but some may still comfortably wear 0–3 month clothing depending on their growth.

Should You Buy Clothes Based on Age?

Not always. Age is only a guideline. The best way to choose baby clothes is by checking your baby's:

  • Weight
  • Height
  • Body shape
  • Brand sizing chart

Two babies born on the same day can wear completely different clothing sizes.

How Fast Do Babies Grow?

During the first six months, babies grow rapidly. Many babies outgrow their clothes every six to eight weeks. This is why many parents avoid buying too many outfits in one size.

Signs Your Baby Has Outgrown Their Clothes

  • Snaps are difficult to close.
  • Sleeves or pant legs are too short.
  • Clothes leave marks on the skin.
  • Baby seems uncomfortable during movement.
  • Neck opening feels tight.
  • Diaper area feels cramped.

Should You Size Up?

Yes, many parents prefer sizing up if their baby is close to the upper weight limit. Slightly larger clothes are usually more comfortable and last longer. Oversized clothing should still fit safely and should not interfere with your baby's movement or breathing.

Best Fabric for a 3 Month Old Baby

Soft, breathable fabrics help keep babies comfortable throughout the day.

  • 100% Cotton

Can a 3 month old still wear newborn clothes?

Most babies have outgrown newborn sizes by three months, although smaller babies may still fit into them.
