study: To assess the middle finger length as a predictor of stature and gender. Methods:
cross-sectional study was conducted on a sample of medical students who attended the 
Department of Forensic Medicine and Clinical Toxicology, Faculty of Medicine, Ain Shams 
University, after obtaining ethical clearance from the ethical committee. Data on age, gender, 
height, and middle finger length were collected. Results: The total number of participants in this 
study was 200 (100 males and 100 females) aged from 18 to 25 years. There was a positive 
correlation between middle finger length (MFL) and stature in both males and females. As 
regards gender determination, the most sensitive variable was left middle finger length (L MFL) 
with 100% sensitivity (and the most specific and accurate test was right middle finger length (R 
MFL) with 65% specificity. Conclusion: The study of middle finger length can help in stature 
and gender estimation among the Egyptian population.
