To be more exact, one acre is 90.75 percent of a 100 yards (91.44 metres) long by 53.33 yards (48.76 metres) wide American football field (without the end zones). The full field, including the end zones, covers approximately 1.32 acres (0.53 ha). For residents of other countries, the acre might be envisaged as approximately 56.68 percent of a 105 metres (344.49 feet) long by 68 metres (223.10 feet) wide association football (soccer) pitch.
