Me: The marketing folks requested I print another set of posters for them but this time “twice as big”, does that mean 2x area or 2x each axis meaning four times bigger?
Boss:  Terry, you’re dealing with marketing people.  They’ve gotten where they are by ignoring fact and figures and going for what “feels” better.
Me: So you’re saying I need to say which “feels” twice as big?
Boss:  Yes, you could say that.  Which print has twice the presence to it?
Me: Presence?
Boss:  Yes.
Me: You agree that this is utter horseshit.
Boss: Yes.

I concluded to double the axes making it four times bigger, as that was twice the “twiceness” that the requester wanted.  I gave them 100% more twiceness than if I just made it twice the size.  That should make them happy.
