A quarter of an acre will give you plenty of food to fill multiple freezers for the year. Some vegetables have a very high yield (potato, tomato, carots). Hens/eggs also have a very good yield, most farms used to have hens. It's nowhere near self sufficiency though. The amount and the variety of things you eat today is tremendous and coming from many places, you're not going to cultivate a fraction of that at home. If you're talking bare subsistence, 1-2 acres of wheat should be enough to feed a family in grain/bread.
