So, you’re looking to buy a new tennis racket.

The size and length of a tennis racket are two essential factors that can have a major impact on a player’s performance. The right racket can help a player hit more powerful shots, achieve better control, and reduce the risk of injury.

However, choosing the appropriate size and length can be a daunting task for many tennis players, especially beginners.

In this guide, I’ll teach you how to find the tennis racket size and length for you, as well as how they can affect your performance.

Let’s go!

Finding the Right Length

The length of a tennis racket is an important factor to consider when choosing a racket that fits your playing style and abilities.

The standard length of a tennis racket is 27 inches (68.58 cm), but there are also shorter and longer rackets available.

How Does Racket Length Affect Performance?

The length of your tennis racket can have a major effect on your performance.

Let’s take a look at how.


The length of a tennis racket can affect how much spin you can generate on the ball.

A longer racket typically provides more leverage and can generate more spin, while a shorter racket may provide less leverage and therefore less spin.

When you hit a ball with a longer racket, the increased leverage can help you generate more racket head speed, which in turn can create more spin on the ball.

However, it’s worth noting that the strings, tension, and string pattern can have an impact on spin.


In general, a longer racket will create more power than a shorter racket due to increased leverage and racket head speed.

This is because swinging a longer racket allows you to cover more distance and generate more racket head speed, which results in more power on your shots.

However, it’s worth noting that a longer racket requires more strength and coordination to use.


I’m sure you already knew the answer to this before reading it.

A longer racket will have a greater reach than a shorter racket.

Even though the difference in length may be minimal, it could be the difference between hitting the tennis ball or not.


Generally, the longer the racket, the more difficult it is to maneuver.

When you swing a shorter racket, it requires less effort and energy to maneuver. This can allow you to make quick adjustments to the ball’s trajectory and react to different shots more easily.

However, manufacturers are aware of this and change the weight and balance of longer rackets to make them easier to maneuver.

Finding the Perfect Head Size

The head size refers to the size of the area where the strings are.

Racket head sizes fall into these 3 categories:

  • Midsize: 85-97 in²
  • Mid-plus: 98-104 in²
  • Oversized: 105+ in²

However, the most popular racket head sizes are 97, 98, and 100 in².

How Does Head Size Affect Performance?

The size of your racket head can have a significant impact on your game.

Therefore, choosing the right racket head size is an important decision that can help you reach your full potential.

Let’s take a look at some areas of your game that may be affected by racket head size.


Typically, as the head size of the racket increases, so does the spin potential.

This is because as the head size increases, the strings are spaced further apart, allowing the ball to embed deeper in the strings and generate more spin.

But it’s worth noting that rackets can also vary in string pattern, which is why a larger head size doesn’t automatically mean an increase in spin potential.

Here are some of the most common string patterns:

  • 16×18
  • 16×19
  • 16×20
  • 18×20

A 16×19 string pattern has greater space between the strings than an 18×20 string pattern resulting in higher spin potential.

Tennis strings can also affect the amount of spin you get on the ball.


A larger racket head size will provide more power, while a smaller racket head size will provide less power.

This is because a larger racket head size has a larger sweet spot, which is the area on the strings that provides the most power when making contact with the ball.

Plus, the larger sweet spot provides a greater margin of error when hitting the ball, allowing for more power to be generated even when the shot is not struck perfectly.


The size of a tennis racket head can also have an impact on maneuverability. Generally speaking, a smaller racket head size is easier to maneuver than a larger racket head size.

This is because a smaller head size racket has less weight in the head, making it easier to swing and maneuver quickly. The smaller size also allows for a more compact and agile swing, making it easier to hit shots on the run or react quickly to fast-moving balls.

However, it is important to note that weight and balance play a huge role in maneuverability as well.

Surface Area

Rackets with a larger head size have a greater surface area, providing the player with a bigger margin for error when hitting the ball. A racket with a smaller head size has a lower margin for error, requiring greater precision to make good contact with the ball.

A larger surface area also means that the racket has a bigger sweet spot, which provides more power and comfort.

This is why rackets with a larger head size are recommended for beginners.

Finding the Right Grip Size

The grip size of your tennis racket is an important factor to consider when choosing a racket as it can impact your comfort, control, and overall performance on the court.

Grip sizes range from 4 inches to 4 ¾ inches. It can also be shown as size 0 to 6.

I’ve included a chart that shows all the different grip sizes below:

4 3/8



4 1/2



4 5/8



4 3/4


Most adults will suit a 4 ⅜ grip size, but you may need to adjust accordingly depending on whether you have small or big hands.

I’ve included an easy-to-follow video below on how to measure your grip size:

Once you have an idea of your grip size, try out different grip sizes to see which one feels the most comfortable and secure in your hand.

You can do this by going into your local tennis store and holding some of the rackets they have on display.

Hold the racket in your dominant hand with your fingers wrapped around the grip and make sure there is enough space between your fingers and the palm of your hand to fit a finger or two.

If you’re not sure which grip size to choose, go with the smaller one because you can always add an overgrip to make the grip larger.

Rules & Regulations

While you can have oversized rackets, there are limits to how big your racket can be.

Racket Length Rules

Under the rules of tennis, the maximum tennis racket length you can have is 29 inches (73.66 cm).

The standard size for a tennis racket is 27 inches (68.58 cm). Rackets shorter than 27 inches are ideal for younger people who are learning the sport. As they progress and get older, a standard size racket would be better suited.

Head Size Rules

The maximum width allowed for a tennis racket is 12.5 inches (31.7 cm).

Tennis rules also state that a racket’s hitting surface cannot exceed 15.5 inches (39.37 cm) in length and 11.5 inches (29.21 cm) in width.

However, most tennis rackets won’t be anywhere near these measurements so you have nothing to worry about.

Plus, these measurements are only for competition play, so if you want to play with a racket that exceeds these measurements in practice, then go ahead!

Final Words

Hopefully, now you have a better understanding of tennis racket size and length.

The next step is finding tennis strings that match your racket.
