Mean values and standard deviations of total body volume, body density, arm volume, height, weight and a battery of 15 measurements of arm comprising different lengths, girths, diameters and skinfolds of 200 Punjabi girls aged 10–19 years are presented. Relationship between arm volume and total body volume in different age groups are also studied. Highly significant and positive correlations existed between arm volume and total body volume and the values of correlation coefficients r ranged between 0.78 to 0.92 in different age groups. Body volume was estimated also from arm measurements by using selective stepwise multiple linear regression analysis for each age group. Highly significant multiple correlation coefficients R were obtained for predicting total body volume from arm measurements and the values of multiple R ranged between 0.92 to 0.97 in different age groups even with a combination of just three or four arm measurements. The most commonly selected measurements up to fourth step in most of the age groups were upper arm girth and maximum forearm girth.
