 Matches were 40 minutes, increased to 50 minutes in 1934, and playing fields 125–130 yards (114-119m) long and 65–70 yards (59-64m) wide.From 1929 until 1979 a second crossbar, a "points bar" was also used, meaning that a point would not be allowed if it travelled over this bar, a somewhat contentious rule through the 75 years it was in use.Teams were regulated at 12 a side, using an elliptical formation, although it was more a "squeezed lemon" formation with the three midfield players grouped more closely together than their counterpart on the half back and half-forward lines.
