WWF’s larger ring

One of the things that always struck me back in the Monday Night Wars (and still stands out when watching old non-WWF stuff on the Network) was the difference in size between the WCW and WWF ring (as well as WCW using cables while the WWF used ropes).  What was the reason for the WWF using a larger ring than pretty much everyone else?

​I think probably because they had larger guys than WCW and wanted to look "bigger" on TV, if I had to guess.  Ring sizes vary so wildly that it was actually kind of unusual for a company like the WWF to have a standardized 20×20 setup like they did.  I honestly never thought about it watching the shows, but then I'm not the most observant person when it comes to that stuff anyway.  ​
