Pedantically, at least a standard US football field is an exact size (120yds long, 53 1/3 yds wide). Soccer pitches? Not so much ... FIFA states the field of play for international matches should be 100-110m long and 64-75m wide (tolerances are relaxed to 90-120m long by 45-90m wide - which oddly means you could have a square pitch). If one would like an example of a comically undersized pitch, look to NYFC playing at Yankee stadium - they had to get a special exemption from MLS, IIRC. Still useful, though, and I think a reasonable person with familiarity with either soccer or football would get a rough idea. Please don't take this as criticism ; it's not meant to be. The mention of football and soccer fields being used as a measure of size in the same sentence sparked recollection of some not-otherwise-useful knowledge stuck in my brain.
