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.

According to Major League Baseball rules, the peak of the mound (where the pitching rubber sits) must be ten and 1/2 inches above the level of home plate (MLB Rule 1.04). The degree of slope from an area six inches in front of the rubber is one inch to one foot (this is in the direction of the plate), and must be uniform. The pitching rubber is legally defined in the rules as the "pitcher's plate".
Although the rules do not specifically say so, it stands to reason that the slope on the back of the mound must be steeper, since the mound is circular and the rubber is toward the back of the mound. The diameter of the mound is 18 feet.

A regulation pitcher's mound is 18' in diameter, the center of which is 59' from the back of home plate. The pitcher's plate (or pitching rubber as it is commonly called) is 18" behind dead center of the mound. The slope from the rubber shall begin 6" in front of the rubber and will slope toward home plate 1" for every 1'. The rubber rests 6" inside the front edge of a level area 5' wide and 34" deep and shall not be more than 10" higher than the playing field.
