MLB, College, And High School Field Dimensions. The 2019 MLB rulebook has the following field dimension requirements: The baseline must be 90 feet. The distance between the home base and the nearest obstruction on fair territory must be at least 250 feet. The home base circle diameter is 26 feet.
The outfield fence in Major League Baseball (MLB) is 400’ | 121.9 m (minimum) in centerfield and a minimum of 320’-350’ | 97.5-106.7 m in left and right fields. The distance of the outfield fence is measured from the apex of home plate.
This creates a field size that is suitable for kids to be able to run around and play defense, but also a reachable fence for the better hitters. The fence typically goes back to around 250-300 feet for middle school fields. Because the fence is an arch, most fields are much deeper in centerfield than the corners.
