Online published on 19 March, 2025. Abstract Introduction Identification of unknown persons is one of the most important steps in forensic investigation. Gender fixation and stature estimation are two important parameters of identification. Sometimes challenging situations arise when medicolegal experts have to give opinion regarding sex and stature from mutilated body parts. Objective The present study has been conducted to measure various dimensions of hand like hand length, palm length, middle finger length and breadth of hand, to search for sexual dimorphism of these dimensions, to estimate statute in both sexes using the above-mentioned dimensions and to formulate regression equation. Methodology The study was performed in Rampurhat Govt. Medical College and Hospital from August 2023 to January 2024 on 584 subjects (384 males and 200 females). Data were collected using slide calliper, put into Microsoft excel office and statistically analysed. Result We found mean value of all the dimension are more in males than in females. We calculated hand index and hand finger index. While hand index is more in males, hand finger index is more in females. An independent t test for all the dimensions are statistically significant and moderately strong positive corelation was calculated between stature and all hand dimensions. Conclusion The data will provide a positive outlook towards human identification by estimating stature and determining gender from different hand dimensions among Bengali population.
