@rygorous@jon_valdes Heh. We used to have to deal with this for Football Manager, and the variability surprised even me, as a season ticket holder. I just looked it up again to check -- allowed dimensions are 100-130 yards x 50-100(!) yards.
We went from a 110 x 73 pitch at the old Tottenham Hotspur stadium to 115 x 75 at the new one five years ago. The size often affects the style of play of the home team, smaller and narrower in particular = more defensive in setup.
