Tennis String Tension: Power vs Control

By Rachel Williams · September 27, 2026

String Tension Basics

String tension is measured in pounds and typically ranges from 40 to 70 pounds. Lower tension provides more power and comfort, while higher tension gives more control and precision. Most recreational players string between 50 and 60 pounds.

Lower Tension (40-50 lbs): More Power

At lower tensions, the strings stretch more on ball impact, creating a trampoline effect that adds power to your shots. This setup is ideal for beginners who need extra help generating pace, and for players with arm issues who want more shock absorption.

Benefits of Lower Tension

Increased power and ball depth
Better comfort and reduced arm strain
More spin potential from string snapback
Larger effective sweet spot

Higher Tension (55-70 lbs): More Control

Higher tension reduces string movement, giving you more precise ball placement. Advanced players prefer this because they generate their own power and prioritize accuracy. The tradeoff is less comfort and a smaller effective sweet spot.

String Type Matters Too

Natural gut holds tension best but is expensive. Polyester strings lose tension quickly and are popular for spin. Multifilament strings offer a good balance. Hybrid setups with polyester mains and gut crosses are popular on the pro tour.

Finding Your Ideal Tension

Start at the midpoint of your racket recommended range (usually printed on the frame). Play for two weeks and adjust up or down by 2 pounds based on whether you want more control or more power.
