- I was looking for sizes of spherical balls to represent the relative sizes of moon and the earth, and demonstrate their actual distance apart.
If a golf ball (moon) is 1.68 in diameter, I looking for ball of around 6.11 inches to represent the earth. There were none on your site but I found playground balls come in various sizes, including 6.1 inch diameter. Your chart is helpful and much appreciated, but playground balls were not on your list. Thought I’d point this out in case other nerds looking at this.
And to answer your question… they’d need to be placed about 15 feet 4 inches apart to reflect the average distance between earth and moon. (Spencer, Jan 2021) - Add different weights of shot put 8, 12 and 16. Tagbro1 (2020)
- ping pong ball is the smallest Mark Abrahams (2020)
- ping-pong = table tennis. Yes, basically the same as the squash ball size, which is listed as the smallest. Rob Admin (2020)
- can you pls add the reason why sports have differences. Adrian (2017)
- Size means diameter so why not say So? This list would be better if it included weight in the same list and was sortable by column or had at least some ordering like smallest to largest. ..
Ps soccer ball is missing from weight list. Barry Milliken (2017)- Hi. I’m not sure what page you read. That size means diameter is written in the first line. The order IS smallest to largest, and the soccer ball is there. Ball weights are listed on a separate page. Rob Admin (2017)

According to the National Operating Committee on Standards for Athletic Equipment (NOCSAE), all lacrosse balls must meet specific regulations to be considered legal for play. The regulation size of a lacrosse ball is as follows:
- Diameter: 2. 5 inches
- Circumference: 7.75 to 8 inches
- Weight: 5 to 5.25 ounces
5 inchesThese specifications ensure that all game lacrosse balls are consistent in size and weight, providing a level playing field for all players.
Variations in Size
While all regulation lacrosse balls must meet the same size and weight requirements, there can be slight variations in size between different brands or types of balls. For example, some balls may have a slightly larger or smaller circumference than others.
It’s essential to note that any ball used in a game must meet the NOCSAE regulations, regardless of any minor size variations. However, some players may have personal preferences for the size or weight of their lacrosse balls, and may choose to use balls slightly different from regulation size.
Importance of Lacrosse Ball Size
When it comes to playing lacrosse, the size of the ball is crucial. The size of the ball affects both safety concerns and gameplay performance.
This section will discuss the importance of lacrosse ball size and its impact on the game.
Safety Concerns
The size of the lacrosse ball is essential for safety reasons. If the ball is too small, it can become a choking hazard for players. On the other hand, if the ball is too big, it can cause injury to players. The size of the ball is also important for goalies, as they need to be able to see the ball clearly to make a save.
In addition, the ball’s hardness can also impact safety. Lacrosse balls are relatively hard, especially when compared to tennis balls and baseballs. This hardness can cause injury if players are hit in sensitive areas, such as the face or head. Therefore, it is crucial to ensure that the ball is the correct size and hardness to minimize the risk of injury.
Gameplay Performance
The size of the lacrosse ball also affects gameplay performance. A ball that is too small or too big can affect the way players catch and throw the ball.
If the ball is too small, it cannot be easy to catch, and if it is too big, it can be challenging to throw accurately.
The weight of the ball is also crucial for gameplay performance. If the ball is too heavy, it can be difficult to throw and catch, and if it is too light, it can be challenging to control. The weight of the ball also affects the speed of the game. A heavier ball will slow down the game, while a lighter ball will speed it up.
To ensure fair gameplay, all lacrosse balls must meet certain specifications. These specifications include the weight, size, and diameter of the ball. The NCAA has specific regulations for the size and weight of the ball, and all game balls must feature labeling that states, “Meets NOCSAE Standards.”
Factors Affecting Lacrosse Ball Size
Several factors can affect the size of a lacrosse ball. Understanding these factors can help you choose the right ball for your game and ensure it meets the required specifications.
Manufacturing Process
The manufacturing process can significantly impact the size of a lacrosse ball.
Balls that are made using different materials or techniques may vary in size. Manufacturers must follow strict guidelines to ensure their balls meet the required specifications.

Measuring Lacrosse Ball Size
A standard lacrosse ball must meet specific size, weight, and diameter requirements.
Below are the tools and techniques used to measure the size of a lacrosse ball and the importance of accuracy and precision.
Tools and Techniques
Measuring the size of a lacrosse ball requires specific tools and techniques. A caliper is the most common tool to measure a lacrosse ball’s size. A caliper is a precise measuring tool that can measure the diameter of an object with high accuracy. You must first open the jaws and place the ball between them to use a caliper. Then, you can close the jaws to measure the diameter of the ball.
Another technique used to measure a lacrosse ball’s size is using a ruler. However, this method is less accurate than using a caliper. To use a ruler, you must measure the ball’s circumference and then divide that number by pi (3.14) to get the diameter.
Accuracy and Precision
When measuring the size of a lacrosse ball, it is essential to ensure accuracy and precision. Accuracy refers to how close the calculated value is to the true value, while precision refers to how consistent the measured values are.
To ensure accuracy, it is crucial to use a precise measuring tool such as a caliper. Additionally, it is essential to ensure that the ball is not compressed or deformed during the measurement process. This can be achieved by placing the ball gently between the caliper’s jaws or ruler.
It is recommended to take multiple ball measurements and calculate the average to ensure precision. This can help to minimize any errors or inconsistencies in the measurements.
How Hard is a Lacrosse Ball
A lacrosse ball is typically made of solid rubber and has a firm texture. It is designed to be dense and durable to withstand the fast-paced nature of the sport. A lacrosse ball is generally harder and less flexible than other sports, such as tennis or soccer balls. It is not as hard as, say, a golf ball, which is made of much denser material. However, it is important to note that the perception of hardness can vary from person to person based on individual sensitivity and comparison to other objects.

Conclusion
Now that you know how big is a lacrosse ball. Remember that all lacrosse balls must meet certain specifications, and only balls meeting the NOCSAE ball standard may be used for competition.
Choosing the right ball for your skill level and position is essential. You may want to use a softer ball to avoid injury if you’re starting. More experienced players may prefer a harder ball for better accuracy and speed.
When purchasing lacrosse balls, ensure they meet the required size, weight, and diameter. You can also choose from different colors, such as white for men and yellow for women, though orange and lime green are also available.
Overall, having the right size and weight of lacrosse ball is crucial for a successful game. Make sure you have the appropriate equipment and enjoy playing this exciting sport!
