what weight is newborn clothes

Newborn clothes usually fit babies around 5 to 8 lb. Some brands use a tighter range, like 5 to 7.5 lb , while others go up to about 9 lb for newborn sizing.

Quick scoop

If you’re shopping for a baby, “Newborn” is the size label , not the weight of the clothes themselves. The clothes themselves are very light , with a typical newborn onesie weighing only a few dozen grams.

Common size ranges

  • Preemie: up to 5 lb.
  • Newborn: about 5–8 lb, depending on the brand.
  • 0–3 months: usually starts around 8–9 lb and goes up from there.

Practical tip

If you’re buying for a baby whose birth weight is unknown, many parents choose newborn plus 0–3 months , because babies can outgrow newborn size very quickly.
