The diagrams available from the Ultimate Baseball Field Renovation Guide show the field from a top-down perspective. The diagrams include dimensions for every element on the field, including how high the pitcher's mound should be and recommended distances for how far the dugout should be placed from the foul line. Dimensions for individual plates are also listed.
On a 90-foot pitch, the home plate and bases sit in the corners of a square that is 90 feet by 90 feet. The foul lines extend out from the two lines that meet to form the home plate.
The pitcher's mound is situated in the center of the square, 60 feet from the home plate. The mound is 10 inches above the height of the home plate, and the radius is 9 feet.
The grass line that separates the infield from the outfield is a quarter circle that runs between the foul lines. The quarter circle has a radius of 95 feet, which is measured from the center of the pitcher's mound.
The base path is 3 feet wide, and the recommended width for the line that demarcates it is 2 1/2 inches.
The home plate, pitching plate, and catcher and batter's boxes all have set dimensions. The home plate is a pentagon measuring 17 inches by 17 inches at its widest points, while the pitching plate is a 24-inch-by-6-inch rectangle.
