If you watch a live baseball game, you should quickly notice how umpires end up with erroneous calls based on the strike zone. So what does the strike zone mean in baseball?

Strike Zone in Baseball: What’s It?
Believe it or not, the strike zone is an invisible element. It only manifests as an imaginary dimension from a hitter’s position. The umpire, hitter, catcher, and pitcher are not looking at an actual box inside the batter’s box.
The only actual manifestation of the zone occurs in the television showcase of a baseball game. The represented strike zone on TV aims to help the audience understand the events involving the ball and the strike. But in reality, the zone is physically non-existent.
According to the Little League University’s Rules, Regulations, and Policies, baseball’s closest strike zone definition is a space above the home plate located in the midpoint between the armpits and above the knees (top of the pants) of the batter.
The umpire determines this position based on the batter’s established posture whenever braces to swing. Consequently, the determination of the strike zone provides a measurement of the umpire’s ability to call either a strike or a ball.
The strike zone dimensions concentrate on both height and width. However, the dimensions only recently surfaced due to errors constantly committed by the umpires when calling for a strike or a ball.
The need for accuracy from the umpire’s end drove the crafting of the official baseball ruling.
Meanwhile, an umpire can only go as far as deciding the strike zone. In a way, the whole act of calling out from a strike zone deems a more subjective approach.
To address this, baseball statisticians decided to develop an averaging template via a rule book. The rule book for baseball strike zone states that an average strike zone height is between 1.5 feet to 3.6 feet starting from the ground.
An average strike zone width is seventeen (17) inches from shoulder to shoulder. This measurement should also directly constitute the home plate width.
What Is the Main Function of the Strike Zone
The strike zone plays an essential role for the hitter and the pitcher. For a pitcher to maintain a pitching strike zone, he must keep track of the outs in opposition to the hitter. The pitcher compels the hitter to get out through the strike zone contacts.
These contacts occur in a series of combinations, namely:
- Called strike
- Missed ball
- Swung ball
- Contact
In the case of the hitter, the strike zone guides him with the best possibilities for a win right on contact. With the strike zone, he is only able to swing at strikes.
Why Does the Strike Zone Differ Between Umpires
The strike zone differs between umpires because the hitter’s stance varies with each swing. Also, the umpires only observe the strike zone from a distance. Lastly, each umpire will have its preferred standards for determining a strike zone or even a strike zone baseball definition.
Some umpires focus more on the area below the strike zone than the top. Others choose to base their calls on the home plate’s width (shoulder-to-shoulder swing movement).
Few umpires look into the individual hitter’s stance. Due to the differences in umpire preferences, strike calls are less accurate.
This subjective perception of the strike zone by the umpire causes arguments (on either ball or strike) to erupt in the field. And according to the official baseball ruling Rule 8.02(a), contestations on the umpire’s calls in the field cannot be tolerated.
And suppose any coach, player, and manager, holding a field position insists on his objection. In that case, the general ruling shall subject him to ejection.
Because of the arguments, experts developed a brand new pitch-tracking system called the Zone Evaluation in 2009. And even with such regulations, people cannot help the strike zone from changing rapidly through the years. In some easy cases, the umpires themselves admit to their errors.
How Is the Strike Zone Enforced
The umpire holds the highest authority for passing judgment on whether the pitch entered the strike zone or not. Official baseball ruling prevents players, managers, and coaches from arguing against the umpire’s call.
The official ruling shall apply to all umpire decisions and even an answer to the question “where is the strike zone in baseball?”.
