Factors to consider when choosing a tennis stringing machine - Buying Guide

Expected Usage

The more you plan to use your tennis racket stringing machine, the more value it has. 

If you string multiple rackets per month, it might compensate you to acquire your stringing machine. On the flip side, if you are an amateur player who plays 2 or 3 times per week, it might not be worth financially wise.

The cost of stringing a tennis racket varies between stores and clubs, but labor costs are typically 10$ to 25$.

Ultimately, it is a question of checking how frequently you plan to use your stringing machine and evaluating how many usages you break even.

As a rule of thumb, a tennis racket played by the typical amateur player must be replaced every 50 matches. This number varies wildly, depending on how hard you hit the ball and what kind of strings you have.

Professional tennis players even switch rackets mid-match because they start losing tension and not performing optimally!

Desired String Tension Accuracy

Another aspect to consider when choosing a machine to string your tennis racket is how accurate you want your tension to be. 

There are 3 types of stringing mechanisms – drop weight (the most basic mechanism), crank, and electronic (the most advanced mechanism) – explained thoroughly below in this article. 

As you progress through them, stringing tension accuracy and the machine’s price increase.

If you are a beginner or intermediate player, you probably won’t feel much difference, and a drop-weight or a crank mechanism is probably the way to go. 

If you are an advanced tennis player, a high-end crank or an electronic stringing machine might be more suitable for your needs.

You might also benefit from our article on how to choose tennis strings – it explains the different types of setups and their expected durabilities, including how much time each material can hold tension.

Stringing Process Speed

You should also consider how much time you wish to spend stringing each racket. While this is not a worry if you are a beginner player who only needs to string his racket sporadically, it will if you plan to string multiple rackets weekly.

As it happens with tension accuracy, higher-end tennis racket stringing machines also speed up the stringing process sharply. 

Stringing a tennis racket using a drop-weight machine will take anywhere between 25 and 45 minutes, depending on your practice and skill. On the other hand, an electronic device will reduce this timeframe to between 10 and 15 minutes (while also being less prone to errors and “sloppy” stringing).

So, if stringing speed is a concern, we advise you to invest in an electronic stringing machine. Otherwise, a crank or drop-weight mechanism will do the trick.


Ultimately, it all boils down to how much you are willing to invest in tension accuracy, stringing speed, and overall accuracy.

A low-end, drop-weight tennis stringing machine’s price starts at 200$/300$. Check out our article on the best budget stringing machine.

Considering that the labor for stringing a tennis racket costs up to 25$, it could be a desirable financial investment, even for the typical amateur player!

Conversely, a premium electronic tennis stringing machine starts selling for around 1000$ and can go up as much as several thousand dollars, depending on its features. This investment, especially when discussing the higher-end of electronic stringing machines, is typically only worth it for tennis clubs or professional stringers.

What to look for in a Stringing Machine - Buying Guide

Stringing Mechanism


Drop weight is the most straightforward tennis stringing machine mechanism. It works with a tensioned weight pulling the string (the heavier the weight, the higher the tension). 

It is the most old-school stringing method, using simple physics (torque = force * distance) to achieve the desired tension.

It is the cheapest type of stringing machine available, the one that requires less maintenance and takes the longest to string a tennis racket. Also, it is typically more prone to “sloppy” stringing if the stringer is not very skilled.


A crank-stringing mechanism uses, as the name implies, a crank to achieve the desired tension – at which point the mechanism locks the string to attach it to the tennis racket.

It is the intermediate-level stringing mechanism.

The stringing speed in this kind of machine is considerably faster than in drop-weight ones.


Electronic tennis racket stringing machines are computerized devices with an electric motor that controls the tension applied to the strings. This is the kind of machine usually found in tennis shops and clubs.

In this category of stringing mechanisms, there are two partitions:

  • Constant pull – the string is constantly being pulled at the desired tension, ensuring that the tension is always incredibly accurate. This is the most advanced and precise type of tennis stringing machine there is.
  • Lockout – The motor pulls the string until it reaches the desired tension and locks it into place. They are also exact, but the tension is not monitored after locking – resulting in micro losses. 

Electronic stringing machines can come with various features, such as single-action clamp bases, string measurers, the possibility to adjust the machine’s height, and electronic brakes. The most modern ones even come with touch screens.

Like tennis ball machines, the more features machines possess, the higher the price.

Standalone or Tabletop

Standalone stringing machines are equipped with stands to string your tennis racket comfortably. Some even allow for adjustable height for comfort.

Tabletop devices are more portable. You can place them on any table or floor to string your rackets.

The decision will depend on whether you need to transport your machine often. 

If so, a tabletop machine is a must. 

If not, we recommend a standalone stringing machine for your comfort.

Mounting System

The mounting system refers to the number of machine points in contact with the racket’s frame when stringing. They can come in 2, 4, 5, or 6 points.

2 and 4 points mounting systems only hold the tension by the throat and head of the racket. 

5 and 6 points stabilize your stringing process and prevent frame distortion (especially on oversized racket heads).

Fixed or Floating Clamps

At last, floating clamps are not attached to the machine and only use one string to hold tension. They are the less reliable method, but also the cheapest.

On the other hand, fixed clamps are commonly attached to glide bars and must be repositioned from mains to crosses. 

Higher-end machines come equipped with fixed clamps that swivel, offering the greatest range of motion, speed, and comfort there is.
