The Little League pitching mound height for younger players is 6 inches, with a base path of 60 feet. For older players, around 11 to 13 years old, Little League increased the pitching mound height to 8 inches in 2013, and the base path is 70 feet for its Intermediate Baseball Division.
The Height Advantage
Pitching mound height plays a significant role in the dynamics of the game. The impact of mound heights is taken into consideration by Little League baseball, with adjustments based upon age and size of the playing field. For example, when Major League Baseball changed the height of pitcher's mound from 15 inches to 10 inches in 1969, the change created quite a stir among players. Pitchers didn't want to give up the greater velocity of the ball thrown from a higher mound. But the game has more batting action with lower pitching mound heights.
