Which measurements are commonly used to estimate stature from long bones in humans?

• A. Length of femur, tibia, humerus measured to maximum length.
• B. Skull width and facial height measurements.
• C. Regressed lengths of tibia or femur (and occasionally humerus) using validated equations considering sex and ancestry.
• D. Pelvic inlet diameter.

Answer: (C)

Estimating height from long bones relies on the strong statistical link between limb bone length and overall stature. In practice, you measure the maximum lengths of long bones such as the femur and tibia, and sometimes the humerus when available. Those measured lengths are not taken as height directly; instead, they are entered into validated regression equations that convert bone length into an estimated stature. Importantly, these equations are often sex- and ancestry-specific because body proportions vary across populations, and including those factors reduces error.

So, the best approach uses regressed bone lengths—tibia or femur, occasionally the humerus—with population-specific equations to predict height. The other options involve measurements that pertain to different attributes (skull measurements for ancestry/sex, pelvic dimensions for sex estimation) and do not provide the standard method for stature estimation from long bones.
