How to Build a High School Baseball Pitcher’s Mound


When learning a new sport, it is important to mimic game conditions as closely as possible. For pitchers, using a pitching mound can help the athlete learn how to develop speed and accuracy. This easy project can be done in your own backyard.

Step 1

Create the material to make the mound. The mound should be composed of dirt, sand and clay divided into equal parts.

Step 2

Draw a circle on the spot where you’d like the mound to be. The mound should be a circle 18 feet in diameter. You must also decide how tall the mound should be. Although standard regulations state that the mound must be 10 inches higher than home plate, some schools have rules specific to them regarding appropriate mound height.

Step 3

Pile enough dirt onto the spot created to meet the diameter and height requirements. Pack the dirt tightly, flattening the top of the mound. There should be a flat rectangle 60 inches by 34 inches on the top of the mound. This rectangle should not be more than 10 inches higher than the playing field. Continue packing the dirt, allowing it to slope down evenly from the top of the mound to the ground.

Step 4

Place a rubber on the pitching mound. This is a white piece of rubber 24 inches long by 6 inches wide, and it is where the pitcher throws from. The rubber should be positioned 6 inches inside the front edge of the rectangle.
