Best tennis strings for power
Top 12 of 14 matching strings in our database. #1 is Babolat VS Touch Natural Gut.
Younger and smaller juniors often cannot yet generate pace on their own. A lively string returns more energy to the ball, so shots land deep with a shorter swing.
Power strings are mostly natural gut and multifilaments, which also tend to be kind on the arm. They give up some control and durability in return.

How we ranked
We kept strings with a power rating of 8 or more (1–10), ranked them by power, and broke ties with the comfort rating.

Questions parents ask
Which string type is the most powerful?
Natural gut, then multifilament. Both stretch and return energy well. Polyester is the least powerful type.
Will a power string make my junior hit long?
It can for players with big swings. If shots start sailing long, move to a string with a higher control rating or string a few pounds tighter.
