A football field is typically measured in yards. The standard measurements for a football field are 100 yards long and 53.3 yards wide. These measurements include the end zones which are typically 10 yards deep. The field is also divided into two equal halves, each measuring 50 yards. The lines on the field are also measured in yards and are used to mark the distance for a first down, the goal line, and the sidelines. The measurements are precise and are required to be the same for all official NFL games.
