Major League (College, High School) Baseball Field Dimensions
Major League Baseball Field dimensions range in size when it comes to the outfield, however all major league ball parks share the exact same infield measurements.
Alexander Cartwright set down the first rules of baseball in the middle 1800's. At that time he set very specific measurements for the infield layout. His rules only set forth minimum size of the outfield.
In this sport, High School and College Baseball Fields share the same infield dimensions as the Major Leagues. That includes the pitchers mound and catchers box areas.
Little League and Youth Baseball Field Dimensions
Little League and Youth Baseball Fields also have very different measurements when it comes to the outfield fence. The infield dimensions however are standardized.
