During 1972 body measurements including height, weight, limb circumferences, skeletal diameters and skinfolds were taken on 100 unrelated and healthy Jat-Sikh men of 17 to 25 years of age, belonging to different areas of Punjab, India. The average height and weight of Jat-Sikhs is 170.4 cm and 54.5 kg, respectively. The mean Heath-Carter somatotype is 3.22-3.40-4.11. The majority of somatotypes is concentrated in endo-ectomorph and meso-ectomorph sectors of the somatochart. Comparisons with recently described data on females of the same area and population show significant sex differences in various body measurements except for the bicristal diameter. The females possess significantly more subcutaneous fat. For the rest of the measurements, the males have higher values. The Jat-Sikh males are comparable in height and weight to the contemporary pooled Punjabi, but are distinctly taller than the neighbouring populations of Himachal Pradesh and pooled all India samples. However, they are comparatively smaller and lighter as compared to European and American populations.
