Objectives To compare a traditional ultrasound (US) method for estimated fetal weight (EFW) calculation and fetal growth restriction diagnosis with 2 newer methods for the prediction of small for gestational age (SGA) at birth. Methods We reviewed deliveries at our institution from January 1, 2013, to March 31, 2017. Singleton, nonanomalous, well‐dated fetuses with a US examination within 2 weeks of delivery were included. Estimated fetal weights and percentiles were calculated by a traditional method (Hadlock et al; Radiology 1991; 181:129–133) and 2 newer methods: Intergrowth‐21st (INTG; Ultrasound Obstet Gynecol 2017; 49:478–486) and Salomon et al (Ultrasound Obstet Gynecol 2007; 29:550–555). We calculated each method's test characteristics to predict SGA (birth weight
