The purpose of the study is to clarify the patterns of distribution of height measurements relative to a specific length of a foot in humans, in order to use them for more accurate and reliable determination of body length (height). 15,892 people of mixed population (9814 men and 6078 women of 49 nationalities) aged from 20 to 50 years were examined. Their heights and their foot lengths were measured, and the coefficients of the ratios were calculated. A chart was made showing the distribution of body lengths relative to different lengths of the feet, in increments of 10 mm. The nature and density distribution of body lengths for each specific foot length were analyzed. The data revealed that each individual length of the foot corresponds to several values of height with a total spread of up to 24 cm at different frequencies of occurrence, which in fact does not allow to unambiguously determine the length of the body (height) of a person relative to the length of his foot. The maximum concentration of body lengths corresponding to a specific foot length is within the proximity of the average value, while significant deviations in one direction or another are much less common - making an exception in 1—3% of cases. The main density of the distribution of height values (76—86%) relative to foot lengths falls within the range of 10—12 cm. This makes it possible with a high degree of probability to determine height relative to foot length within these limits. The ratios of foot length to height, calculated in various ways, differ from each other. In this regard, the ratio between height and foot length, established by anthropologists and shoe designers/ergonomists - including methods for determining height, based on their calculations — are poorly suited for forensic science and forensic purposes.
