WCD generally has nothing to do with wide, long, square, or even the amount of wheels or type of wheels. It comes in all shapes and sizes, just like any other drive style. This style seems to be defined by the cantilevered wheels, which makes it easy to service.

Our drivetrain (WCD) this season would of been square, if not for the balls being so wide. Our base ended up being 28x27, wide. (We need just that extra inch for our intake to work
) With a six wheel drop center, the thing handled like a dream.
For an example of a square 4 wheel WCD, see 2590's 2013 robot

Its all about the effective
wheelbase compared to the track. When building a skid style drivetrain where unlike cars or bikes the front wheels wont pivot to turn, too small of a wheelbase will result in uncontrollable turning (turning to well). Too big of a wheelbase, and you'll have trouble turning. Its simply a ratio.
