10 inches
6" high.
little league- 40 ft (35 ft for the 7-8 year olds) high school- 43 ft as of 2011 college- 43 ft
Pitching mound dimensions are as follows: Diameter: 18 feet Height: 10.5 inches at the rubber, with a plateau at the top of the mound 5 feet wide. Distance to HB: 59 feet (60', 6" from back tip of home plate) The pitching rubber is 18 inches behind the center of the mound (10 feet in front of rubber and 8 feet behind rubber). Dimensions of the rubber are 24 inches by 6 inches.Slope: Beginning 12 inches in front of rubber a line extended to HB will fall 1 inch for every 1 foot of distance until it is level with the plate.
40 or 43 feet
From high school on, it is 60' 6".
The distance from the pitching rubber to the back tip of home plate in professional, college and high school baseball is 60 ft. 6 in. In some leagues 13-14 will pitch from that same distance, but in some they will throw from 54 ft. as a transition from little league to high school. I would check with your rules for your league and work from there.
The distance from home plate to the pitcher's mound in Little League is 46 feet. High school, college, and Major League Baseball standard is 60 feet and 6 inches (a mistake in measuring long ago but was left that way). Pitcher's mound distances are ALWAYS measured from the front of the rubber to the rear tip of home plate.
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.
Flower Mound High School was created in 1999.
The pitching mound serves a clear purpose, even if its origin is not clear. When the pitcher strides not only forward but slightly downward (away from the highest point of the mound) as the ball is released, more energy is transferred to the ball, and it attains a greater speed. In 1969, when the National League (this writer ignores that other league), lowered the height of the mound by five inches, the purpose was clear. Along with the simultaneous decrease in the size of the strike zone this rule change benefitted hitters at the expense of pitchers. Whether the league admits it or not, these moves were intended to make the game more exciting for those fans who liked to watch high-scoring games rather than the so-called "pitcher's duel". One may infer that the mound was instituted originally for the opposite purpose: to make things easier for the pitcher and harder for the hitter.
It varys, I play in a 12u league and we pitch from 40 feet but I'm sure in higher league(high school, college, etc.) they pitching mounds will be further away
