Summary. . The value of fetal biparietal diameter and abdominal area, total intrauterine, intra‐amniotic and placental volume measurements for predicting small‐for‐dates babies in a high‐risk obstetric population was investigated in 130 women. A parallel planimetric area method was used to measure volume. The commonest risk factors were suspected intrauterine growth‐retardation, hypertensive complications and previous poor obstetric history. The prevalence of birthweight at and below the 10th or 3rd centiles was 30 and 16% respectively. Fetal abdominal area and total intrauterine volume measurements had the highest and comparable sensitivity, specificity and positive predictive value in the detection of infants with birthweights of 10th and 3rd centiles. While these measurements are of use in consolidating the clinical diagnosis of small‐for‐dates fetuses (growth retardation), high false positive rates (10% and 16–17% for birthweights 10th centile, and 3rd centile respectively) make further discriminatory tests necessary for part of the population.
