An area measurement device (200) having a support (202) to be moved around a boundary. A direction indicator (220) determines the directional orientation of the support (202) and creates direction data. A distance indicator (218) determines the distance traveled by the support (202) and creates distance data. A microprocessor (110) receives the direction data and distance data and calculates the area inside the boundary based on this data.
