How often do you change your tennis balls? There’s no exact timeline, but we bet you’re not changing them as frequently as you should. 

Over time tennis balls will get fluffed up, lose their pressurization and their bounce. The more you play, the earlier the balls’ flatness will start bothering you. Depending on how often you play will affect how quickly the tennis ball becomes flat.

For casual players playing once a week, we find you can usually get up to 5 sessions out of a pack.

Experienced players who play often, will only play with a pack of balls once to maintain the consistency and avoid minute changes in the bounce and firmness.

Professional players will usually get a pack of balls every set (30-45min) or sooner.

At Wimbledon, balls are changed every seven and nine games alternatively. The spare balls are stored in a refrigerator container at the side of the court.

Since balls need to be replaced often, they can add up to a lot of waste.

An estimated 400 million tennis balls and 125 million tennis ball cans are purchased and discarded annually, adding to landfills and other environmental challenges. 

To help cut down on that waste, Wilson introduced the Triniti Ball, the sustainable alternative tennis ball that maintains its fresh ball feel 4x longer than a standard rubber tennis ball core.

This new core eliminates the need for pressurized plastic packaging. Triniti comes in a recyclable and biodegradable cardboard sleeve, made with 100% FSC certified materials, thus reducing our contribution to the 125 million tennis ball cans that end up in landfills globally each year.

With a combination of innovative ball technology and unique sustainable packaging, Wilson Triniti ushers in a new era for tennis balls.
