Level of play

The size and dimensions of a baseball field differ with the level of play. If you notice carefully, you can easily find that the gully leagues or any youth or amateur league occurs in comparatively smaller fields. And professional baseball matches are being played on larger fields.

Park factors

The size of the baseball field is also affected by the layout and position of the stadium or park. If the pre-existing stadium is in an odd position, the organizers have to reduce the overall size of the field. 

Weather and climate

Weather or climate plays a very crucial role in any field. If it is rainy weather, then you need to give a special emphasis on the drainage of the field. Heavy rains can make the field muddy and slippery. While running on such a field, the players may face injuries. So in some cases, to prevent these injuries, the organizers reduce the size of the baseball field.

Similarly, in the heavy wind, the game also gets affected. Strong wind de-tracks a flying ball from its projection. Sometimes, the field position also gets adjusted to counter this type of heavy wind. 

Moreover, baseball fields can be adjusted based on weather and climate conditions to ensure that the game is fair and safe for all players.
