How Many Feet in a Smoot?

A smoot is a distinctive and informal unit of length that comprises 5 feet 7 inches. This unconventional unit owes its name to Oliver R. Smoot, a Harvard graduate student who, in 1958, became the unwitting source of measurement for the Harvard Bridge.

The Smoot’s Origin

Oliver Smoot’s unusual claim to fame began when he was used as a “human ruler” to measure the length of the Harvard Bridge, which spans the Charles River in Massachusetts. His friends, humorously and somewhat haphazardly, laid him down end-to-end 364 times across the bridge. Remarkably, the bridge was found to be exactly 2,310 feet long. As a result, the smoot became synonymous with 5 feet 7 inches.

Usage of the Smoot

The smoot is not an official unit of measurement, but it has found a place in informal and often humorous descriptions of distances. People might playfully state that something is “a smoot long” to add personality to their language. For instance, you could say, “The new building is a smoot tall,” meaning it is 5 feet 7 inches in height.
