Hello, First of all, thank you very much for your interest in Madmext. Based on the height (175 cm) and weight (72 kg) information you shared, we recommend you to choose **M (Medium)** size for our **Black Men's Regular Fit Shorts 4842** model. Our product, due to its regular fit (standard cut), will neither be too tight nor too loose on you, and will provide comfortable use. If you prefer a looser and more comfortable look in shorts, you can consider one size larger (L), or if you want a tighter fit, you can consider one size smaller (S). However, according to your general measurements, the most ideal look will be provided by size M. We wish you pleasant shopping! Best regards, Madmext Team
