Forensic anthropologists employ in estimating stature from fragmented body parts or human skeletal remains. This study aimed at investigating the inter-racial difference between adult Egyptian and Bengali populations regarding the body stature and tibial length, developing regression equation formulae using the percutaneous length of tibia (PCTL) to estimate stature. Four groups of adult male and female Egyptian and Bengali subjects aged ˃21 were recruited randomly. Body height and PCTL were measured using the standard anthropometric technique. The means of the stature of the studied groups exhibited significant differences between all groups (p < 0.001) except in Egyptian females versus Bengali male (p=0.067). There was no significant difference within the same sex of both ethnic groups regarding the tibial length (Females p=0 .490) and (Males p=0.905).The measured parameters of males were significantly higher than the corresponding female values. The linear regression equations derived for male and female Egyptian were 94.080+2.145 x T (± 3.57) and 76.617+2.375 x T (± 3.89), respectively. Those for male and female Bengali were 92.500+1.870 x T (± 2.93) and 105.563+1.473 x T (± 2.39), respectively.  It was concluded that the derived equations are flexible and retain realistic standard errors that can be used for stature estimation using the length of an intact mutilated leg. These equation formulae are Sex and ethnic specific. Thus, they should be endorsed in anthropological studies for stature estimation among the ethnic groups under this study.
