>>> football pitches arent the same?
The Laws of the Game state that the length of a football pitch can be anywhere between 90m and 120m, with a width anywhere in between 45m and 90m. (A pitch can't actually be square though, at 90m x 90m, but it can be very close to it, at say 91m x 90m. Equally, it can be long and thin, at 120m x 45m, so the shapes of football pitches vary quite a lot).
Individual competitions though are entitled to fix the sizes of their pitches, with the Premier League opting for 105m x 68m. (The Spurs pitch is shorter though, at only 100m, as there's not enough space in the ground to accommodate a full-length pitch).
Pitches for international matches have to be between 100m and 110m in length and between 64m and 75m wide. Sheffield Wednesday's pitch used to be a maximum size international pitch but it's now been reduced in size. (I ran a line at Hillsborough back in the 1980s. I kept thinking "I must be near the centre line now", as I ran sideways along the pitch, only to find that I was nowhere near it!)
