The strike zone is your target area as a pitcher. If you are a batter, it is the area that you want to protect. Anything thrown within this area is considered a “strike”. Anything thrown outside of this area is regarded as a “ball”. This zone is what your umpire uses to determine whether each pitch is a ball or a strike. If a batter swings and makes contact with a pitch, it is determined a strike. It does not matter where the location of the pitch is. Strike zones should be pretty standard in every league. You may find that umpires expand or reduce a zone depending upon the level of play.
In this blog post, we’ll take a closer look at the strike zone and what goes into determining whether or not a pitch is considered a strike.
What is the official baseball strike zone?
The official strike zone in baseball is a vertical rectangle. It extends the width of the plate. This includes the black siding of the plate. The bottom of the zone begins just below the knees. The top of the zone reaches the midpoint between the shoulders and the top of the pants. Only a portion of the ball needs to pass through any part of the zone to earn a strike.
What’s the Point of the Strike Zone?
The point of the strike zone is twofold. It forces your pitcher to throw good pitches and forces batters to swing at good pitches. Since there is a limit to the number of strikes a batter can take and a number of balls a pitcher can throw, the strike zone encourages both pitchers and batters to make choices. A strike zone forces both the batter and the pitcher to be aggressive.
What is the Average Size of a Strike Zone?
The average size of a strike zone will depend upon the size of the batters. It will change from game to game and from year to year. It will also depend on the level in which your player is playing.

Are all strike zones the same?
All strike zones should be the same in the same league. Is the strike zone in little league the same as major league?

Two umpires within the same league may have a slightly different zone. So while the strike zone is the same, the interpretation of the pitches may be different. You may also notice that umpires expand or reduce zones to avoid lopsided games.

No umpire will get every call correctly. In fact the highest rate umpire in the Major Leagues has an accuracy rating of close to 97%.
Why is the Size of the Strike Zone Not a Universal Height?

If you watch a game on tv then you will notice that replays will show a strike zone for a hitter and where the ball landed. MLB Commisioner, Ed Manifred, has commented that there is a system that works and there is a potential to use the electronic system in place by the 2024 season.
How Does the Strike Zone Effect the Game?
The strike zone affects the game in a number of ways. The use of a strike zone implements strategy. Depending on what type of pitcher you have, will determine what part of the strike zone will be used.
