I'd say that the space available determines game size, and I'd rather not heave my entire collection to club so I've been reduced to playing 28mm Renaissance on either the coffee table or the dining table (about 2' by 3'6") - now covid has struck its a bit of an academic question.
If I had a garage where I could lay out an 8' table I would.
I would say that figure scale doesn't impact game size as much as you might imagine, for example: a unit of 10 WotR longbows in 28mm on 20x20 bases measure 100x40mm, 4 stands of 15mm bowmen (3 minis per stand) on 30mm square bases are 120x30mm.
