What are the official dimensions of a baseball field?

The Infield

The infield is shaped like a diamond with home plate at one corner. The four bases are positioned 90 feet apart from each other in a square. First base, second base, and third base mark three corners of the diamond, while home plate marks the fourth corner. The pitcher's mound sits in the center of the diamond, 60 feet and 6 inches away from home plate.

The Outfield

The outfield extends beyond the infield and is bounded by the foul lines that run from home plate down the first and third base lines. The minimum distance from home plate to the foul line is 330 feet on both sides. The distance to center field must be at least 400 feet from home plate. Different stadiums can have different outfield dimensions as long as they meet these minimum requirements.

Foul Territory

Foul territory is the area outside the foul lines that runs from home plate along both baseline sides. The foul lines themselves are considered fair territory. Anything hit beyond the foul lines or outside these lines is considered a foul ball, except for certain situations involving fair balls that go into foul territory.

Official Field Layout

Major League Baseball sets official standards for field dimensions. The warning track, a strip of dirt or different material in the outfield, is typically 350 to 400 feet from home plate. The backstop behind home plate must be at least 60 feet away. Dugouts are located along the first and third base lines where the teams sit during the game.
