In the official rules for Major League Baseball, it is stated that the outfield fence should be at least 250 feet from home plate. A distance of 325 feet or more along the foul lines and 400 feet or more to center field has since become mandatory for any new stadiums.
RECOMMENDED AREA Ground space is 1.2 acres minimum. SIZE AND DIMENSION: Baselines are 60'. Pitching distance is 46'. Pitcher's plate is 6 above the level of home plate. Distance down foul line is 200'. Outfield distance to pocket in center field is 200' to 250' optional. ORIENTATION: Optimum orientation is to locate home plate so that the pitcher is throwing across the sun and the batter is not facing it.
