Everything You Ever Wanted to Know About High Altitude Tennis Balls
The first thing you need to know about playing tennis at high altitude is that altitude has an impact on tennis balls and how they perform.
Living here in Salt Lake City where the elevation is 4,500 ft above sea level, it is important to use high altitude tennis balls for their adjusted performance.
If you’ve ever traveled from lower elevation to higher elevation with a sealed plastic container like a plastic water bottle or a bag of potato chips, then you’ve seen that container expand and contract as you go up and down in altitude.
If you start at high altitude and come down, you’ll notice a water bottle will contract inward and collapse the bottle’s sides. If you go from low altitude and go to high altitude, when you unscrew the bottle lid, you will hear the increased inner pressure release almost like opening a soda bottle.
Tennis balls are pressurized, so, if you take a tennis ball that was manufactured and pressurized at five hundred feet above sea level, and you take that ball to 4,000 ft (or higher), the air will expand inside the tennis ball and make it bounce more because the pressure inside the ball will increase dramatically.
Because of this, manufacturers have made alterations to high altitude tennis balls to adjust for the change in air pressure.
High altitude tennis balls have a harder (and heavier) inner core than regular tennis balls. This gives them a different feel than a standard tennis ball made for lower elevations. Some tennis pros have been known to adjust their racket tension when using high altitude tennis balls to help offset the weight of the ball.
If you live in the mountain west or anywhere in the world above 4,000 ft in elevation, high altitude tennis balls are a critical piece of tennis equipment.
What Are High Altitude Tennis Balls?
High altitude tennis balls are specially designed tennis balls intended for use at higher altitudes where the air pressure is lower. High altitude tennis balls are engineered to offer optimal performance in regions where atmospheric pressure is lower, typically above 4,000 feet.
Standard tennis balls are pressurized, and at high altitudes, the lower air pressure can cause these balls to bounce too high and fast, making it challenging for players to control their shots accurately.
To address this issue, high altitude tennis balls are manufactured with a different internal pressure compared to standard balls. These balls have less internal pressure, which helps regulate their bounce, making them more suitable for play in high-altitude conditions.
Players at high-altitude locations often opt for these specialized tennis balls to ensure a more consistent and predictable performance on the court.

Are High Altitude Tennis Balls Made Differently?
Yes, high altitude tennis balls are manufactured differently from normal tennis balls to account for the effects of lower air pressure at high-altitude locations.
The key differences lie in the internal pressure and design of these specialized tennis balls:
1. Internal Pressure: High altitude tennis balls have a lower internal pressure compared to regular tennis balls. This adjustment helps regulate the bounce of the ball at higher altitudes where the atmospheric pressure is reduced. By reducing the internal pressure, these balls can provide a more consistent and controlled bounce for players.
2. Material Composition: The material composition of high altitude tennis balls may be tailored to enhance their performance in low-pressure environments. Manufacturers may use specific materials or modify the construction of these tennis balls to optimize their playability under high-altitude conditions.
3. Durability: Due to the unique demands of playing tennis at high altitudes, high altitude tennis balls may be designed to offer increased durability to withstand the challenges posed by the environment. This enhanced durability ensures that the balls maintain their quality and performance throughout extended matches.
Overall, the manufacturing process and specific features of high altitude tennis balls are tailored to address the impact of high-altitude conditions on ball behavior, enabling players to enjoy a more consistent and reliable playing experience in such environments.
High altitude tennis balls are typically crafted using specialized materials to optimize their performance in low-pressure environments. The materials used in manufacturing these tennis balls are chosen for their ability to maintain consistency and durability under high-altitude conditions.
Are the Materials Used to Make High Altitude Tennis Balls Different?
Not really. Tennis balls are made of vulcanized rubber with a felt cover. High altitude tennis balls are the same. However, the way they assemble those components does change for high altitude tennis balls.
Here are some common materials used in the production of high altitude tennis balls:
1. Rubber: The core of high altitude tennis balls is made of vulcanized rubber like all tennis balls. But, with high altitude tennis balls, the rubber is usually thicker.
2. **Felt**: The outer surface of high altitude tennis balls is covered with felt, which is typically made from a blend of wool and synthetic fibers. The felt covering affects the ball’s texture, aerodynamics, and overall feel during play. It is crucial in maintaining grip and enhancing control for players, especially in challenging high-altitude conditions.
3. **Internal Pressure Regulation Materials**: Manufacturers incorporate specific materials or technologies to adjust the internal pressure of high altitude tennis balls. These internal components help stabilize the ball’s bounce and ensure consistent performance despite the atmospheric challenges posed by high altitudes.
4. **Adhesive and Sealants**: Special adhesives and sealants are used in assembling high altitude tennis balls to maintain their structural integrity and prevent air leakage. These components help keep the internal pressure at the desired level, ensuring that the ball performs optimally throughout its use.
By carefully selecting and combining these materials, manufacturers create high altitude tennis balls that are tailored to excel in low-pressure environments, providing players with a reliable and predictable playing experience at elevated locations.
Why Don’t They Use Nitrogen to Pressurize High Altitude Tennis Balls Instead of Air?
If you live in the mountain west and are used to having your tires inflated with nitrogen, you may have wondered why tennis ball manufacturers don’t use nitrogen.
After all, nitrogen reacts less to changes in altitude, which is why they are good for inflating tires in the mountain west region of the United States – your tire pressure doesn’t change much going up and down the mountains.
The reason high altitude tennis balls are not inflated with nitrogen, or partial nitrogen is that it tends to “escape” where natural air tends to stay contained. Because of this, tennis ball manufacturers continue using natural air to pressurize high altitude tennis balls.

Summary - A Guide to High Altitude Tennis Balls
The lower internal pressure of high altitude tennis balls helps regulate their bounce on the court, providing a more consistent and predictable performance for players. The materials used in these tennis balls are specifically chosen to maintain consistency and durability under low-pressure environments.
While the core material of high altitude tennis balls remains the same as regular tennis balls (vulcanized rubber), it is usually thicker to withstand the challenges posed by high altitudes. The outer surface of these tennis balls is covered with felt, which plays a crucial role in maintaining grip and enhancing control for players.
Manufacturers also incorporate specific materials or technologies to regulate the internal pressure of high altitude tennis balls. These internal components help stabilize the ball’s bounce and ensure consistent performance despite atmospheric challenges.
Despite the benefits of using nitrogen as a pressurizing agent in other applications, it is not commonly used in high altitude tennis balls due to its tendency to escape. Therefore, natural air is still the preferred choice for pressurizing these specialized tennis balls.
High altitude tennis balls are meticulously crafted to provide a reliable and predictable playing experience for players at elevated locations. By utilizing specific materials and manufacturing processes, these tennis balls can withstand the challenges of low air pressure and offer consistent performance throughout extended matches.
Whether you are a professional player or a recreational enthusiast, high altitude tennis balls are an essential equipment choice for playing at elevated locations (Like Most of the Mountain West).
