Background: Almost every bone in the human skeleton exhibits sexual variation. The humerus, a large bone in the upper limb, is commonly used to determine sex due to its very stable condition. Aim of the study: The goal of the current study is to evaluate various measures of the humerus to determine sex. Methods: This study was conducted in Department of Anatomy, Anwer Khan Modern Medical College, Dhanmondi, Dhaka, Bangladesh, from June 2023 to June 2024. This cross-sectional study examined on 200 well ossified humeri, among them 100 were male and 100 were female humeri. Each bone was thoroughly examined to determine any obvious abnormalities. The study looked at six measurements: maximum length of the humerus (MLH), maximum diameter of the humeral head (MDH), vertical diameter of the humeral head (VDH), transverse diameter of the humeral head (TDH), condylar breadth (CB), and epicondylar breadth (EB). All data was collected, documented in a Microsoft Excel work sheet, and analyzed using descriptive statistics in SPSS 23.0. Results: Male and female participants had MLH measurements of 305.86 ± 11.19 mm and 282.88 ± 6.78 mm, respectively. Male and female MDH measurements were 42.75 ± 1.81 mm and 39.86 ± 1.62 mm, respectively. The VDH measured 41.54 ± 1.63 mm in males and 38.88 ± 1.52 mm in females, respectively. Males had a TDH of 38.28 ± 1.82 mm, while females had 35.77 ± 1.49 mm. Males and females had EBs of 54.23 ± 4.60 mm and 49.64 ± 8.27 mm. The CB measured 37.17 ± 2.22 mm in males and 34.29 ± 1.08 mm in females. A value below the stated threshold was categorized as female, while a number over it was classified as male. For example, a maximum humerus length of more than 289.6 mm is classified as male, whereas a length less than 289.6 mm is classified as female. The threshold values for MDH, VDH, TDH, EB, and CB are 42.6 mm, 41.7 mm, 39.9 mm, 55.4 mm, and 36.5 mm, respectively. Conclusion: This study found that the maximum length of the humerus and vertical diame
