Baseball Field Dimensions

Baseball is a very popular sport not just in America and Japan but in many countries all over the globe.  Baseball fans are obsessed about anything and everything about baseball but do you know about the baseball field dimensions?  The baseball association has regulations and dimensions that have to be followed by every league and every organization when the sport is being played.

The important parts of a baseball field are the following:

  • The Baseball Diamond
  • The Home Plate
  • The Bases
  • The Batter’s Box
  • The Umpire Box
  • The Pitcher’s Mound

1). The Baseball Diamond

Although the outfield measurement may vary for each baseball field depending on the size of the field, the infield must be 90-foot square.

2). The Home Plate

The home plate should be at the center of a 26-foot diameter.  The home plate should be a17-inch by 17 inch.  The distance between home plate and first and third bases should be 90 feet. The foul lines should start from the home plate up to 325 feet until the pole marker.  Pole markers are set to mark the foul lines and halfway through, the wall or fence must be four hundred feet from home plate.  This is an official rule of the baseball organization and must be strictly followed.

3). The Bases

The bases must be fifteen inch squares with thirteen feet surrounding arcs.  The distance between each base must be 90 feet.

4). The Batter’s Box

The regulation size of the batter’s box is four feet by six feet.  It should be 6 inches from the home plate.  This is an official regulation of the baseball organization.

5). The Umpire Box

The umpire box is generally forty-three inches by eight feet.  The umpire’s box is important to give the umpire enough space to monitor the game and the players.

6). The Pitcher’s Mound

The pitching mound should be a 24-inch by 6-inch pitching rubber.  The pitcher’s mound should be at the center of the baseball diamond.  The pitcher’s mound must have a diameter of 18 feet and must be high above the home plate by 10 ½ inches.  The distance between the pitcher’s mound and the home plate should be 60 feet and 6 inches.
