Methods: Cross Sectional Study designe was used.Eighty-six physical therapy students were selected randomly, and their age were ranged from 18-27 years. They were divided into three groups according to BMI. The first group with normal BMI (18.5-24.9 Kg/m2), while the second group was overweight (BMI was ranged from 25-29.9 Kg/m2). The third group was obesity class I (BMI was ranged from 30-34.9 Kg/m2).Photogrammetry method used (the photographic sessions by mobile phone Samsung J-7 Camera and use of Corel Draw software to analyze the pictures). Results: A significant difference was detected between normal BMI and overweight (p0.2), and for SA non-significant difference between normal BMI and obese (p>0.41) and non-significant difference between overweight and obese (p>0.2). Conclusion: overweight and obesity change CVA and forward head posture and overweight changed SA and so rounded shoulder appeared. However, obesity did not change SA and rounded shoulder.
