What is the official height of the Olympic women's 100-metre hurdles?

The official hurdle height in the Olympic women’s 100 metres hurdles is 0.84 metres.

That height is commonly expressed as 84 centimetres. The event uses ten hurdles placed along a straight 100-metre course. Athletes begin from blocks, clear the barriers, and race to the finish; touching a hurdle is permitted, but deliberately knocking one down can lead to disqualification under the rules.

The women’s event differs from the men’s 110-metre hurdles in both distance and hurdle height. The senior men’s hurdles are 1.067 metres high, so confusing the two measurements is a common mistake. The women’s Olympic event replaced the earlier 80-metre hurdles at the 1972 Games.

Modern races emphasize rhythm as much as raw speed. Efficient athletes maintain a consistent stride pattern between hurdles while minimizing the time spent airborne.
