How Much Does A Baseball Weigh?

Have you ever wondered how much a baseball weighs? It might surprise you that the answer can vary slightly depending on the ball type and who makes it.

Let’s take a closer look at the weight of different types of baseballs and see why they are all slightly different. 

Major League Baseballs 

The most common type of baseball is the official Major League Baseball (MLB). These balls must meet certain MLB specifications, including a weight range between 5 and 5¼ ounces. The core comprises rubber-like cork, surrounded by two layers of wool and two layers of cotton yarn. The outer layer is then covered in cowhide leather that has been treated and rubbed with wax to make it soft and easy to grip. 

Youth Baseballs 

The size, shape, and weight requirements for youth baseballs vary by league. However, most youth leagues use balls that are either 11 or 12 inches in circumference with a weight between 4½ and 5 ounces. Youth balls are usually made from synthetic leather instead of cowhide for increased durability. 


Compared to baseball, softballs are larger (12-14 inches) and lighter (around 6 ounces). Softballs have a core made from cork or rubber, surrounded by two layers of wool yarn, one layer of wool yarn, and one layer of cotton yarn. The outer layer is also made from synthetic leather material for increased durability.  

MLB Baseballs Controversy

Over the past few seasons, there has been a lot of controversy surrounding the baseballs used in Major League Baseball. Some people believe that the baseballs have been altered to make them more “juiced” and thus lead to more home runs being hit.

This debate came to a head in 2019 when MLB set a new single-season record for home runs. There were 6,776 home runs hit during the regular season, an increase of nearly 1,100 from the previous season. This led many to believe that something was different about the baseballs being used.

MLB has denied any wrongdoing, saying that the balls are within the guidelines set by the governing bodies. However, some players and experts have doubts and believe the baseballs are altered in some way to make them livelier and lead to more home runs. The constant changing of the baseballs used in games continues to be a hot topic for discussion.


As you can see, there isn’t one definitive answer as to how much a baseball weighs; it depends on which kind you buy! Generally speaking, Major League Baseballs weigh between 5 – 5¼ ounces, while youth baseballs usually weigh about 4½ – 5 ounces. Softballs weigh around 6 ounces because they are bigger than regular baseballs but not as heavy due to their synthetic leather coverings.
