Yes there is a regulation size for Major League Baseball fields, in the case of the infield, it needs to be a 90 foot square. The outfield does not have any regulation size between the 2 foul poles, their regulation size is only in the case of its distance to home plate so the distance between home plate and the Outfield fence must be at least 250 feet however along the foul lines the distance between the plate and the outfield fencce must be at least 320 feet and the distance must be at least 400 feet between the plate and the fence in Center Field.
For Little League (7 - 12 year olds), the distance is 60 feet.

A baseball field is larger and it has a pitching mound. A softball field has an extended first base to protect the fielder and runner.
