Standards of triceps and subscapular skinfold thicknesses for 1293 Caucasian newborn infants of gestational ages 37-42 weeks, and of 0-25 kg birthweight intervals between 2-25 and 4-5 kg are presented. Female infants had a greater skinfold thickness than males, and the subscapular skinfold was greater than the triceps. The skinfold thickness in both males and females declined after 40 weeks of gestation.
