A typical Wegman's is 140,000 sq. ft. The one in Tyson's is 70,000.
That said, the Tyson's one has most of the stuff that Wegman's is known for - great bakery, cheese, wine, meat, charcuterie and produce. Where they save space is on the more typical groceries. For example: only stocking small amounts of paper products and limited choices of items like salad dressings.
