Size at Birth by Gestational Age

We created the curves on this page from a study that collected data from the neonatal registry at the Rabin Medical center from 1991 to 2005 (1). A total of 85,320 neonates were born during that period, with data available for 42,085 males and 39,953 females. We constructed curves from the 3rd to 97th percentiles and for gesstational ages 26-42 weeks( weight at birth), 33-42 weeks (length at birth) and 30-42 weeks (head circumference at birth).
