Three hundred ninety fetal crown‐rump measurements by ultrasound echography were performed in order to correlate the crown‐rump length with gestational age between the sixth and fourteenth weeks of gestation. A blind trial in 58 patients showed a good correlation of ultrasonically determined age and menstrual age. A graph of normal values was designed and is currently being used in routine work.
