About this calculator

BMI from weight and length, classified according to the BMI curves for preterm infants by Olsen 2015.

Postmenstrual age = gestational age at birth + age since birth. For classification at birth (SGA/AGA/LGA), completed weeks are customary; here the curves are interpolated to the day.
