Washington Monument "shorter" than originally thought

Posted: Updated:
WASHINGTON, D.C. (KWWL) -

Recent measurements by the National Oceanic and Atmospheric Administration (NOAA) say that the Washington Monument doesn't match up with the measurements from when the statue was erected back in 1884.

NOAA's geodetic survey has the monument standing at 554' 7 and 11/32" tall, but back in the 19th century, the statue was 555' 5 and 1/8" - or about 10" shorter.

The surveyors are sighting the difference to a change in the way the measurements were conducted, and they say they're careful when comparing historic heights because they don't know the measurement's starting point from 1884.

Today's measurements are based on the International Standards Measurement of a building's height; NOAA says technological improvements probably helped with accuracy, as well.
