Having the right water polo ball is necessary if you're practicing, performing in a match, or trying to show your favorite sport to someone new. When you want the best water polo balls and other gear, S&R Sport gives you the best option. Whether you need a practice ball for young kids or an official-size ball for professional play, we can meet your needs. It’s also important to note, in the United States the sport is called water polo, while in Europe, it's called waterpolo, so they will refer to the ball as a waterpolo ball.

To perform well in any sport, one needs the right gear. In water polo, the ball is the main focal point of the game. Although the ball looks similar to those used in other sports, it is designed to withstand the conditions of a very demanding water sport. Here are some basic specs to know.

• Materials. Water Polo balls are made from rubber, which is flexible, durable, and gripping. Players must hold and throw the ball with strength and control on the slippery, wet surface.
• Color. Standard water polo balls are yellow, which is preferred for their visibility. Balls also tend to have black stripes and may have team logos.
• Size. Water polo balls are available in various sizes, which vary according to the level of play. 

How to Choose the Correct Water Polo Ball Size 

In some sports, ball size is standard for all levels of play. Not so in water polo, where you need the appropriate size. Sizes range between 1 and 5. The following is a breakdown of which size you want for different purposes. 

Size 1

The smallest water polo ball size is recommended for children between 2 and 6. It may also be called a “mini-trainer” or “splash ball,” as it’s inappropriate for older players. Size 1 balls are smaller and lighter than professional-quality balls, made to match the size and abilities of young kids. They are perfect for helping children learn basic skills and become more confident in the water. 

Size 2

Known as a junior ball, this size is commonly used for girls aged 12 and under and co-ed for 10 and under. Size 2 allows young players to graduate from splash ball to water polo. It’s an intermediary step between splash balls and standard-size water polo balls. 

Size 3

A size three water polo ball, also known as an intermediate-level ball, is used by boys 12 and under and girls 14 and under. It’s designed to help young players develop higher-level skills they can perfect as they reach higher levels. Size 3 balls are typically used in training and youth leagues. 

Size 4

Size 4, a compact water polo ball, is used in Women’s Olympics events, 16s, 18s, girls HS, and the Women’s Open. It’s also used in leagues for boys 14 and under. With a size between .65 and .67 meters, it’s slightly smaller than the men’s size (5).

Size 5

A water polo ball size 5 is the official size for men’s events, including men’s Olympics events, NCAA and international men, and 16 and under boys. The size is between .68 and .71 meters, requiring more advanced control than petite balls. 

Inflating a Water Polo Ball

Properly inflating water polo balls allows them to operate correctly. Inflating balls with a standard hand or bicycle pump is simple, and electric inflators make it even faster. Remember always to wet the inflation needle before use. Otherwise, you risk damaging the valve. 

The recommended levels are 12-13 psi (pounds per square inch) for Size 4 balls and 13-14 psi for Size 5 balls. No official standards exist for more petite balls, so you must use your judgment when inflating them. 

Maintenance Tips For Water Polo Balls

Here are some guidelines to ensure a water polo ball performs optimally and lasts as long as possible. 

Check Inflation Levels

Water polo balls are constantly in motion and get hit, so they deflate over time. To keep them in top condition, watch them and inflate them regularly to an appropriate level. A poorly inflated ball can lead to failed shots, passes, and poor training habits. 

Clean Regularly

After every game or training session, the water polo ball should be rinsed and cleaned. Some chemicals, like chlorine in pool water, can harm the ball's surface. The balls can be cleaned with fresh water and a damp cloth. Mild soap is recommended, but harsh cleaning products should be avoided.

Only Use Them in the Water

Kids and adults are used to throwing and bouncing balls on the ground. However, a water polo ball is only made for water. Dust and other dirt easily get picked up, and hard surfaces like pool decks wear out the material. 

Proper Storage

Water polo balls should be stored in a cool and dry place when not in use. They shouldn’t be kept in direct sunlight or under extreme temperatures. Prolonged sun exposure can damage the ball’s rubber coating. Water polo teams and clubs often store balls in mesh bags or on metal carts. When transporting balls, keep them in a secure bag.

Replace When Necessary

As with any sporting equipment, a water polo ball eventually has to be replaced. Using damaged or worn-out balls isn’t good for practice and can worsen the quality of competition. It’s not good for training either. Look for signs of wear, such as tears in the covering or air leaks.
