You may also want to share your family size.
When mine was a family of four, I wanted something more than 12 tomato plants (trellised) for fresh and cooked from fresh. If canning and freezing was added in, the total number of plants jumps to more than 36. or most of your plot.
Corn could be any block shape bigger than 6 by 6 feet for fresh.
On a number of my home-sized gardens size was not enough, so pole beans became much more important.
One or two zuccini was always plenty.
