Step 1
Mix the soil for the pitching mound. The soil should consist of equal parts dirt, sand and clay.
-
Step 2
Outline a circle for the mound. The regulation pitching mound is a circle 18 feet in diameter.
-
Step 3
Determine how high your pitching mounds needs to be. Some leagues have specific rules regarding mound height. If no specific mention of mound height is in your rules, the standard regulation mound height is 10 1/2 inches higher than home plate. Pile the soil to this height.
-
Step 4
Flatten the top of the mound. The regulation pitching mound consists of a flat circle on top 5 feet in diameter.
-
Step 5
Slope the soil down evenly from the edge of the 5-foot circle to the ground. You can create an optional pitcher's landing spot by flattening a second spot about half-way down the front-side slope of the mound. Make the landing a square 2 feet by 2 feet.
-
Step 6
Add a rubber to the pitching mound. This is where the pitcher throws from. It should be 60 feet and 6 inches away from home plate. The rubber must be a white strip of rubber 24 inches long and 6 inches wide.
-
Step 7
Place the rubber in the middle of the pitching mound, but slightly toward the back of the mound. The rubber should be 10 feet from the front of the pitching mound and 8 feet from the back of the mound.
