How To Check Badminton String Tension? -Guide

If you wonder how to check badminton string tensions, here are the best methods and devices to help you check the string tension.

The string tension of the badminton racquet plays a key role in a player’s ability to hit the ball. Depending upon the skill level and style of play, different players stick to different tension levels of the string bed. Before you start a game, it is crucial to ensure that your racquet has desired string tensions. If you wonder how to check badminton string tension, here is everything that you need to know.

Before we jump to the methods through which you can check the string tension on the racquet it is crucial to understand what is the string tension and how it works.

string tensions work and its type

String tension refers to the amount of pressure or tightness applied to the strings of a badminton racket. It is a crucial factor that influences the performance and characteristics of the racket during gameplay.

String tension works by determining the amount of energy transferred from the player’s stroke to the shuttlecock upon contact. When the strings are strung at a higher tension, they become tighter and provide less give or elasticity. This results in a more controlled and precise shot, as the shuttlecock receives less energy and the player can better manipulate its direction and speed.

Dynamic Tension

The overall stringbed stiffness is called dynamic tension. Once the racquet is fully strung, the stiffness of the overall stringbed is referred to as “dynamic tension”.

Linear Tension

Linear tension is the tension that is used as a reference on the stringer machine when you string the racquet. It is a measure of the force applied by the stringer on an individual string in a linear manner or in the directions in which it is being pulled. The string stiffness is entirely different from the linear tension commonly known as string tension.

Why Do You Need To Check The String Tension?

A racquet is strung by using the reference tension value on the stringer. As soon as the racquet is taken off the stringing machine it starts to lose the tension. When you play your first game, the tension is significantly reduced. Here are some methods through which you can check the badminton string tension:

1. Racquet Diagnostic Center

RDC by Babolat is the most authentic machine that you can use to check the badminton string tension or measure the tension loss in the badminton racquet strings. The dynamic tensioner or stiffness of the stringbed is measured by RDC by securing a racquet handle to the machine. Pressure is applied on the racquet head that causes the string to flex.

In response to that flex, the machine can measure the overall stiffness or tension of the string bed. This is an authentic way of measuring tension but the machine is very expensive. RDC by Babolat can measure various other properties of the racquet along with string tension or stringbed stiffness, it costs around $5000.

2. RacquetTune

  • RacquetTune is an App available for iPhone and Apple devices. It can measure the change in tension as small as 0.2 lbs.
  • Place the phone near the racquet and make sure everything around you is quiet and there is no vibration around the phone or racquet.
  • Then you need to strike the strings lightly with an object like a pencil.
  • The app also uses an accuracy indicator that lets you know the accuracy of the result you get.
  • Since it is based on the sounds generated by string, it is not very reliable and many players have reported inconsistent results.
  • Though it’s not a good option for technical applications, on a regular basis you can make some solid guesses about the string tension of your racquet.
  • You can also save the racquet data for further analysis and compare the values with the values you get in the future.

Popular String Meters for Checking Badminton String Tension

String meters are the device commonly available in the market that is used to measure the tension of string or badminton racquets. These are simple devices consisting of two prongs, springs, and a dial. These are mechanical devices and you need to be highly skilled to get an accurate value tension on the racquet.

Two famous string meters are Gamma String Tension Tester and Tourna Stringmeter. These devices come with 2 prongs that are inserted between the intersection of two strings.

It should be somewhere in the center of the string bed. Then the user twists the device to measure the tension and you can read the value on the dial or scale. You can check the tension by inserting the prongs into the various parts of the stringbed. These devices are available between $20 to $40.

Electronic String Meters

If you want to improve the accuracy, you can use an electronic string meter. These electronic devices are manufactured by various brands and cost you somewhere between $190 to $250. These devices come with digital screens and use vibration to measure string tensions. Unlike mechanical string meters, electronic string meters utilize advanced technology to provide more accurate and precise readings.

With electronic string meters, users can quickly and easily determine the exact tension of their badminton strings, allowing for precise adjustments and optimal performance. They are especially beneficial for professional players, stringers, and enthusiasts who require precise and consistent string tension measurements.

The device is clamped on a string bed. The clamp sends out vibration and the data is used to measure the final tension on the list string. Though they are expensive, e-string meters are known for more consistent and accurate results.

Wrapping Up

I’m hopeful this guide will help you understand how badminton string tension works and how you can check badminton string tension. The best way to measure string tension is an electronic string tension meter like ERT 300 Tennis Computer by Gamma Sports. They are competitively priced and let you measure the tension with better accuracy.
