Large for gestational age (LGA) is a term used to describe infants that are born with an abnormally high weight, specifically in the 90th percentile or above, compared to other babies of the same developmental age.[1][2][3] Macrosomia is a similar term that describes excessive birth weight, but refers to an absolute measurement, regardless of gestational age.[4] Typically the threshold for diagnosing macrosomia is a body weight between 4,000 and 4,500 grams (8 lb 13 oz and 9 lb 15 oz), or more, measured at birth, but there are difficulties reaching a universal agreement of this definition.[4]

Evaluating an infant for macrosomia or LGA can help identify risks associated with their birth, including labor complications of both the parent and the child, potential long-term health complications of the child, and infant mortality.[5]
