I don't know what a regular Walmart is other than they vary greatly. The first Walmart Supercenter opened in Missouri in 1988 and was 125,000 square feet. The last Hypermart was the one I spoke of above and it exceeded 225,000 square feet. Almost double the size. It was indeed very big. The one in Topeka, Kansas was converted to a Supercenter and we still shop there once in awhile. It is huge.
