One acre equals 0.0015625 square miles, 4,840 square yards, 43,560 square feet or about 4,047 square metres (0.405 hectares) (see below). While all modern variants of the acre contain 4,840 square yards, there are alternative definitions of a yard, so the exact size of an acre depends on which yard it is based.
An acre is a measure of area. An acre is equal to 43,560 square feet. So a half acre is equal to 21,780 squre feet. If you are looking at houses, a 100 ft wide and 200 ft deep lot (pretty common for new houses in areas that do not have very high housing prices) is 20,000 square feet and just under 1/2 an acre.
