What is the Best String Tension for Average Tennis Racquets?

Here you will find the differences between high and low tensions of strings and how they affect your game in detail. There is always a specific tension applied to the crosses and main strings of the tennis racquet when it is strung, whether it is done at the factory or by your local stringer.

As the stringing machine pulls the string through the racket, tension is measured by the weight this exerts on the string, expressed either in kilograms or pounds. Also, check BEST TENNIS BALL MACHINE 2021 (TOP Rated REVIEWS)


It is just as important what string you use in your tennis racket as the tension of the strings you pull in the frame. You must know what effect tension leaves on your racquet.

String tension influences two variables from a physics perspective:

  • Restitution coefficient (elasticity of ball-racquet contact)
  • Dwell time coefficient (length of time the ball stays on the strings)

If you need help determining what tension to have your racket strung, you can ask yourself these three simple questions. Be sure to answer each question to find out what string tension is best for your game.

1.What kind of string material do you use?

Are you using nylon/gut, polyester, or a hybrid string? Beginning players should prefer nylon strings, those in the intermediate stage can choose hybrids, and those in the advanced categories can use full polyester beds. Tension is primarily determined by the elastic nature of the media which we’ll refer to as the base recommendation.

Stringing loser is recommended if using stiffer string material, such as polyester. To start out with, we’d aim for the following tension levels:

  • A nylon/gut-weight between 50 and 60 pounds (22.5 to 27kg)
  • The hybrid weight range is 46-56lbs (21-25.5kg
  • Polyester fabric with a weight of 44-54lbs (20-24.5kg)

2. In what way do you hope to benefit?

Are you interested in controlling your strings? The strings on beginner rackets should add more power to shots while the strings on advanced rackets should provide more control over shots. As your string tension increases, you will have more control, whereas as your string tension decreases, you will have more power. For power or control, I have recalculated the above tension ranges:

A nylon/Gut setup would weigh 50-60lbs (22.5-27kg).

  • Power: 50-55 pounds (22.5-25 kg)
  • Control: 26-30 lb (25.5-27 kg)

The weight of hybrid string is 46-56 lbs (21-25.5kg) ( Since nylon is a softer material, a polyester string is 2lbs (1kg) looser)

  • The power range is 46-51lbs (21-23kg).
  • Weight Control: 52-56lbs (23.5-35.5kg).

The weight range for polyester is 44-54lbs (20-24.5kg)

  • The power ranges from 44-49 pounds (20-22kg)
  • Control: 50-54lbs (22.2-25.45kg)

3. What game level are you at?

In order to decide what string tension is best for your game, you need to know how good you are on the court. For each of these levels of tension, here are those ranges again.

A nylon/Gut setup would weigh 50-60lbs (22.5-27kg).

  • Power: 50-55 pounds (22.5-25 kg)

1.     For a beginner: 70-75lbs (26-27 kg)
2.   For an intermediate: 52-53 lbs (23.5-24kg)
3.   For advanced: 50-51 pounds (22.5-23kg).

  • Control: between 56 and 60 pounds (25.5-27kg)

1.    For a beginner: 59-60lbs (26.75-27.25kg)
2.    For an intermediate: 57-58lbs (26-26.5kg).
3.   For advanced: 55-56lbs (25-35kg)

The hybrid weighs between 46 and 56 lbs (21-25.5kg)

Power Range: 46-51lbs (21-23kg)

  1. For a beginner: 50-51lbs (22.5-23kg)
  2. For an Intermediate: 48-49lbs (21.75-22kg)
  3. For advanced: 46-47lbs (21-21.5kg)
  4. Control Weight: 52-56 pounds (23.5-25.5 kg)
  5. For a Beginner: 55-56lbs (25-25.5kg)
  6. For an Intermediate: 53-54lbs (24-24.5kg)
  7. For Advanced: 52lbs (23.5kg)

The weight of Polyester is 44-54lbs (20-24.5kg).

  • Power range of 44-49 pounds (20-22 kilograms)
  • For a Beginner: 44-45lbs (20-20.5kg)
  • For an Intermediate: 46-47lbs (21-21.5kg)
  • For Advanced: 48-49lbs (21.75-22kg)
  • Control weight should be between 22 and 24 kg (50 to 54 pounds).
  • For a Beginner: 50lbs (22.5kg)
  • For an Intermediate: 51-52lbs (23-23.5kg)
  • For an Advanced: 53-54lbs (24-24.5kg)

The string tension of your racquet can have a significant impact on your play, and that subtle tweak can help you make a successful shot, or give you that extra boost to match up well with your opponent. You need to keep in mind that changing tension won’t fix technical or fitness problems, or poor equipment choices in general.

The tension you should use is totally up to you. There is no wrong or right answer. If you can’t match every inch of a pro stock frame, I wouldn’t recommend copying the professional players blindly.

It would be beneficial to conduct a little test in the mid-50s to see how the average player reacts to this. If you are prepared to restring your racket regularly, you will always need to keep in mind that tension loss happens relatively quickly and that 55lbs will soon be 50lbs. Choosing your preferred tension amounts to deciding how often you want to restring your racket.
