According to official regulation, the weight of a baseball ranges from 5 to 5.25 ounces. Read on to see what determines the sizes and weight of the ball and more.

How Heavy Does a Baseball Weigh?

Baseball is a sport of bat and ball. Hence, all the techniques and tactics of teams and player positions in the entire game center around these two items.

That’s why the construction of the baseball bat and ball and the forces between them are critical to the sport.

The official baseball weight, therefore, is the result of thorough calculation and modifications. Furthermore, there will be slight differences in game balls used in high school baseball, minor leagues, and MLB games.

1. Standard baseball

Now, in official games, the average weight of a baseball is 5 ounces to 5.25 ounces. It means the baseball weight in grams is 142 to 149 (or 0.142 – 0.149 kg). In pounds, it measures from 0.3125 to 0.328.

If we compare a baseball to a softball, a softball weigh more at 6.25 to 7 ounces.

2. Rubber baseball

For younger players, the balls are made to be lightweight, significantly more than the standard ones used in professional leagues like MLB or the national leagues.

These soft compression balls weigh around 4.2 ounces (119 grams), as they are made of sponge rubber. We can see this type of ball in Little League or games for amateur players.

3. Low-compression baseball

Another lighter ball for Little League baseball is the low-compression one, measuring around 4.6 ounces (130 grams).

As you throw the ball, you can feel how squishier and lighter it is, compared to major league baseball and college baseball.

4. Leather and synthetic leather balls

Unlike lightweight rubber baseballs, leather balls weigh a bit more, as these materials are more heavy-duty.

Genuine leather baseball measures around 5 ounces, while synthetic leather balls might weigh approximately 5.1 ounces. Therefore, they are basically the same weight as standard baseballs.

In the course of more than two decades of baseball history, the balls and their raw materials have undergone major transformations to become the official ones we know today.

Here are some significant periods in the evolution of the ball manufacturing process and the constructions used.

1. Lemon peel ball

Modern baseball for the MLB is produced by Rawlings using a standardized manufacturing process. However, in the early days of the sport, pitchers fashioned their own balls.

During the “Lemon Peel Ball” period, the majority of baseballs had a core composed of melted yarn and leather of old shoes or fish eyes. In addition, these balls were small, dark brown, and had four rows of stitches.

With this design, they had a greater rebound and a longer trajectory.

2. Live ball and dead ball era

Fast forward fifty years to the 1850s, standardizing baseballs became an essential goal for teams in New York. The conventional baseball at the time had a circumference of 8 to 11 inches and a weight of 5.5 to 6 ounces.

However, there were still many types of baseballs that offered distinct feels and speed due to differences in the hand-made process and materials. There were two popular types at that time:

3. Figure-8 baseball design

Figure-8 baseballs are also known as modern-style baseballs because the stitches are lined up to form the number 8.

These balls were mass-produced by William Harwood’s facility, America’s first baseball manufacturing factory.

4. Cork-core ball

In 1910, the cork-core ball era began. The cork-core ball was tougher, so a baseball player could hit it harder. This resulted in higher batting averages and the live ball area starting, effectively ending the dead ball period with low hits and scores.

Then, Australian wool was utilized to create baseballs in 1920, combined with machine winders for a tighter wrap. However, this Australian yarn ball made little difference in the game.

In 1925, a baseball featuring a cushioned cork core and both black rubber and red rubber coverings was produced.

Close to a decade later, the American League and National League finally reached an agreement on the baseball’s structure in 1934. At this point in time, the ball’s anatomy was as follows:

5. World war II cork ball

Due to the fact that cork and rubber were not common materials during World War II, balata, a rubber-like material, was utilized for baseball in 1943.

After the introduction of synthetic rubber in 1944, the usage of rubber cores was reinstated.

Baseball Design and Dimensions

As you already know, a MLB baseball weigh 5 ounces to 5.25 ounces, and is produced by Rawlings.

The baseball design includes a core, covering layers made of leather and wool, along with hand-stitched red threads. Let’s break down the mass of a baseball:

The official baseball diameter is 9 inches to 9.25 inches, which translates to 22.9 to 23.5 cm).

Frequently Asked Questions (FAQs)

What is the average life of a baseball?

The lifespan of a game ball is only seven pitches, and occasionally even six pitches. The ball is discarded and a new one used whenever it makes contact with the ground or a bat.

A typical MLB game will employ between 84 and 120 baseballs.

How many stitches does a Baseball have?

The outer layer of the baseball made of red threads are called stitches. A baseball has 216 single stitches (108 double stitches).

How many ounces in a pound and in a kg?

There are 16 ounces in 1 pound and 35.27 ounces in 1 kg.

So, for measuring the baseball weight, 5 ounces to pounds will be 0.3125, which is the exact weight of the baseball. And 5 ounces to kg will generate a result of approximately 0.142.

Conclusion

Now, you know that a Major League Baseball weighs around 5 to 5.25 ounces and that MLB baseballs differ from soft baseballs used in little league and high school baseball.

Furthermore, the new ball today has experienced multiple changes, from the live ball era and the early dead ball era, to the introduction of the revolving machine and mass production. There are indeed many fun facts derived from a simple question, “how much does a baseball weigh? “
