110 metres hurdles 100 yards (91.44 m). The first standards were attempted in 1864 in Oxford and Cambridge: The length of the course was set to 120 yards (109.7 m) and over its course, runners were required to clear ten 3 foot 6 inch (1.07 m) high hurdles. The height and spacing of the hurdles have been related to Imperial units ever since. After the length of the course was rounded up to 110 metres in France in 1888, the standards were pretty much complete (except for Germany where 1 metre high hurdles were used until 1907).

The idea of using 27-inch (68.6 cm) hurdles was introduced in Europe in 2000. The increment does not exist on standard hurdles, which caused resistance from some NGBs, but the rules were adopted worldwide. Many modern hurdles will not go to that height or would at least require modification to cut the hurdle. Most facilities that have spent thousands of dollars to buy regulation hurdles would certainly not let their hurdles be damaged
