## What is the Diameter of a Regular Baseball?

Baseball is a popular sport that is played throughout the world. It is a game that has been around for centuries and is still enjoyed by millions of people. The game of baseball is played with a bat and a ball, and the size of the ball has an important role in the game. The size of the ball affects the trajectory and speed of the ball when it is hit, so it is important to know what the diameter of a regular baseball is.

### Types of Baseballs

There are several types of baseballs that are used in the game of baseball. The most common type of baseball is the “regular” baseball, which is used in Major League Baseball and most recreational leagues. The regular baseball is also known as the “official” baseball and has specific dimensions that must be met.

Other types of baseballs include the “youth” baseball, which is slightly smaller than the regular baseball, and the “softball”, which is even smaller than the youth baseball. Softball is commonly used in recreational leagues and is often used to teach the fundamentals of the game to children.

### The Diameter of a Regular Baseball
