Stature Estimation from Long Bones

How the stature estimation from long bones works

Long bone length correlates strongly with living stature, so a regression equation converts one to the other. Trotter and Gleser published the most widely used set in 1952 and 1958, with separate equations by sex and reference sample, each carrying its own standard error.

The femur gives the tightest correlation and the radius the loosest. Because every equation has a standard error of three to four centimetres, the honest output is an interval, and stature also declines with age, which the correction handles.

Frequently asked questions

How is height estimated from a femur?

By regression. For the Trotter & Gleser White male equation, stature in centimetres equals 2.38 times the maximum femur length plus 61.41, with a standard error of 3.27 cm.

How accurate is stature estimation from bone length?

The standard error is typically 3 to 4 cm, so a 95 percent interval spans roughly 12 to 16 cm. It should always be reported as a range.

Can these equations be used on Indian remains?

Not without caution. Trotter & Gleser derived them from mid-twentieth-century American samples, and limb proportions differ between populations. For Indian casework, regressions derived from Indian skeletal samples should be used instead.
