Question: what is the average birth weight for triplets?
Answer: The average weight of a triplet is 1700 grams (3 pounds, 12 ounces), which is half the weight of the average single newborn (3400 grams, 7 pounds, 6ounces). More than a third of triplets weigh less than 1500 grams (3 pounds, 3 ounces) at birth. Less than 1500 grams is called very low birth weight.
