On the exterior, the Doric columns measure 1.9 metres (6.2 ft) in diameter and are 10.4 metres (34 ft) high. The corner columns are slightly larger in diameter. The Parthenon had 46 outer columns and 23 inner columns in total, each column containing 20 flutes. (A flute is the concave shaft carved into the column form.)
