Monitoring body fat and controlling it is an important factor in checking people's health and efficiency. This factor is especially important in students because physical fitness plays a key role in better performance and health of their body and mind, therefore, this article was conducted with the aim of relating the thickness of skin folds in different areas of the body in male students. In this study, 120 male students aged 19 to 24 years of Isfahan University were randomly selected and the fat thickness of the octagonal points of their body was measured 3 times using a Seka caliper with an accuracy of 0.1 and the results were measured using descriptive and inferential statistics such as Pearson's correlation coefficient. It was analyzed with version 21 of spss software. Mean and standard deviation of subscapular fat (14.95±5.5), forearm fat (6.13±2.9), back arm fat (11.92±5.04), breast fat (9.9) 9.6±3), belly fat (19.4±8.8), extra-specific fat (14.7±8.9), thigh fat (16.5±6.7), leg fat (6 It was 11.4±5.00, so there was a high correlation between the thoracic region with the subscapular and abdominal regions (82%) and (80%) and on the other hand, the abdominal region had a high correlation with the supraclavicular region (78%). Also, there is a high correlation between the back of the arm and forearm and thigh (83%) and (84%) and between the leg and thigh (85%) (p<0.01). The results of this study show that body composition can be evaluated in the measurement with a smaller number of positions.
