If you've ever played official Little League Baseball or have a child that does, you know that Little League field dimensions are smaller than their Major League Baseball counterparts. A wild guess for why that is would be that children are smaller and weaker than adults. What’s no joke is that roughly three million kids play Little League in the United States and many more in other countries. The kids (and the parents) take it all very seriously. A standard set of rules has been developed that apply to Little League games, and these include the dimensions of the playing field.
Batter's Box – The dimensions for the batter’s box in Little League are three feet wide by six feet long. The dirt circle surrounding the batter’s box should extend out at a radius of nine feet before the grass infield. The distance between the left and right side batter’s boxes should be 25 inches.
Basepaths – The distance between the bases in Little League is 60 feet. Thus, there are 240 total feet around the baseball diamond. In Major League Baseball, the distance between bases is 90 feet, or 360 feet around around the diamond. Little League bases should be squares that measure fourteen inches by fourteen inches and at least three inches high.
Pitching Mound – The distance from the front of the pitching rubber to home plate should measure 46 feet in Little League Baseball. In Major League Baseball, that distance is 60 feet and six inches. The rubber itself should be eighteen inches wide and four inches in depth. The distance from the pitching rubber to the beginning of the outfield grass is typically 50 feet in Little League.
Outfield – Dimensions for the outfield fences vary, but it should be at least 175 feet to left and right field down the lines and up to 225 feet to center field. However, the most recommended dimensions are 200 feet from home plate to all parts of the outfield fences. The height of the fencing is recommended to be four feet high.
