This example illustrates potential confusion around non-square pixels. 5 football fields long makes perfect sense, but I'm not sure if 2 football fields wide means "twice the width of a football field" or "width equaling twice the length of a football field". I would lean towards the latter in colloquial usage, which means that the area is definitely not the same as the area of 10 football fields

I would lean towards the former. I really don't think people are trying to compare the width to the length when discussing football fields casually.

If I told you parking spots are about two bowling lane's wide... I'm obviously not trying to say they are 120ft wide.

I don't think that's obvious at all if you're talking about the length and the width and not describing something I know to be much smaller in any dimension than the length of a lane.
