The top of the rubber on the pitchers mound is to be no higher than ten inches (25.4 cm) above home plate. From 1903 through 1968, this height limit was set at 15 inches, but was often slightly higher, sometimes as high as 20 inches (50.8 cm), especially for teams that emphasized pitching, such as the Los Angeles Dodgers, who were reputed to have the highest mound in the majors. A higher mound usually works in favor of the pitcher.
I was wondering how high the pitchers mound was in little league?
