How accurate are Trotter-Gleser stature estimates?

Standard errors of estimate range from ±3.0 to ±4.5 cm depending on the bone and group. Femur regressions are among the most accurate; pooled-ancestry equations are less precise than population-specific ones.

Which long bone gives the best stature estimate?

The femur and tibia together give the most accurate stature reconstruction (SEE ±3.0 cm). The femur alone is second best (SEE ±3.7 cm). Arm bones (humerus, radius) have larger errors (±4.5 cm).

Stature Estimation from Femur (Trotter & Gleser)

Estimate living stature from femur length using Trotter and Gleser regression equations, stratified by sex and ancestry (White, Black, East Asian). Used in forensic anthropology and bioarchaeology for skeletal analysis.

How It Works

Each component has a specific meaning:

Femur length — The femur length recorded for the scenario being assessed.

Note: Interpret the stature from femur result against the thresholds and context described above.

How to Use

Enter the femur length for the scenario you are assessing. Estimate living stature from femur length using Trotter and Gleser regression equations, stratified by sex and ancestry (White, Black, East Asian). Used in forensic anthropology and bioarchaeology for skeletal analysis. Use the stature from femur result to inform your calculation.
