Why Proper Tennis Racket Sizing Matters

Choosing the correct tennis racket size for your child is vital for several reasons. Firstly, an improperly sized racket can lead to discomfort and potentially cause injuries, such as tennis elbow or shoulder strain. Secondly, using a racket that is too large or too small can negatively impact your child’s technique and overall performance on the court. Lastly, providing your child with a properly sized racket ensures they can develop their skills in a safe and efficient manner.

Determining the Right Racket Size

To determine the appropriate tennis racket size for your child, you need to consider their age, height, and strength. Manufacturers generally provide guidelines based on age and height ranges, but keep in mind that every child is unique, and individual variations may exist. It is crucial to take these guidelines as a starting point and make adjustments based on your child’s specific needs.

Measuring Techniques

1. Age-based Approach

One common method used to determine racket size is the age-based approach. This approach provides a general idea of the racket length suitable for a child based on their age group. However, remember that children can vary in height and strength, so this method should only be used as a rough guideline.

  • Ages 4-5: 19″ – 21″ racket length
  • Ages 6-8: 21″ – 23″ racket length
  • Ages 9-10: 23″ – 25″ racket length
  • Ages 11 and above: 25″ – 27″ racket length

It’s important to note that as children grow at different rates, it’s crucial to reassess their racket size periodically, even within the same age range.

2. Height-based Approach

Another approach is to consider your child’s height when selecting a tennis racket size. This method takes into account the fact that taller children generally require longer rackets to accommodate their reach.

Here is a general height-to-racket size guideline:

  • Under 3’11” (120 cm): 19″ racket length
  • 3’11” – 4’6″ (120-137 cm): 21″ racket length
  • 4’7″ – 4’11” (138-150 cm): 23″ racket length
  • 4’11” – 5’2″ (151-158 cm): 25″ racket length
  • Over 5’2″ (158 cm): 26″ or 27″ racket length

It’s essential to consider both age and height when determining the appropriate racket size. If your child falls within a specific age range but is taller or shorter than average, adjustments may be necessary.

Considering Strength and Playing Style

While age and height are important factors, considering your child’s strength and playing style is equally crucial. If your child is stronger or more advanced for their age, it may be appropriate to select a slightly longer racket. On the other hand, if your child is smaller or less experienced, a shorter racket can offer better control and manoeuvrability.

To assess your child’s strength, observe their ability to swing the racket comfortably. If they struggle to swing with control or if the racket feels too heavy for them, consider selecting a lighter option. Additionally, consider their playing style. If your child prefers a more aggressive and powerful game, a longer racket may provide added leverage and reach.

Testing the Racket Size

Once you have determined the recommended racket size for your child, it’s time to ensure it feels comfortable and suits their playing style. Here are some steps to follow when testing the racket:

  1. Grip Size: Check if the grip size is suitable for your child’s hand. A proper grip size allows for a comfortable and secure hold on the racket. To determine the appropriate grip size, have your child hold the racket in their dominant hand. There should be enough space between their fingertips and the base of their palm to insert a finger comfortably.
  2. Swing Test: Have your child swing the racket and observe their form. The racket should feel balanced and easy to manoeuvre, allowing for smooth swings and control over the ball. Observe if the racket feels too heavy or too light for your child. Ideally, they should be able to generate sufficient power without sacrificing control.
  3. Reach Test: Ask your child to reach for a ball, both overhead and at the sides. Ensure that they can comfortably reach without straining or overextending their arm. The racket’s length should enable them to reach the ball effortlessly while maintaining proper form.

By performing these tests, you can make any necessary adjustments to ensure the racket size is appropriate for your child.

Other Considerations

Racket Weight

Besides the racket size, it is essential to consider the weight of the racket. Lighter racket’s are generally recommended for beginners and younger children as they provide better maneuverability and reduce the risk of fatigue. As your child progresses and gains more strength, you can gradually introduce slightly heavier rackets to enhance power and control.

However, it’s crucial to strike a balance. Avoid selecting a racket that is too heavy for your child’s current capabilities, as it may hinder their technique and increase the risk of injury. Consult with tennis professionals or knowledgeable experts who can guide you in selecting an appropriate racket weight based on your child’s age, strength, and skill level.

Grip Size

A proper grip size is crucial for your child’s comfort and control over the racket. An ill-fitting grip can lead to discomfort, affect technique, and potentially cause injury. To measure the correct grip size, have your child hold the racket with their dominant hand. There should be enough space between their fingertips and the base of their palm to insert a finger comfortably. If the grip feels too small or too large, consider selecting a different grip size or using an overgrip to achieve a more secure and comfortable hold.

String Tension

While string tension may not directly relate to racket sizing, it’s worth mentioning as it can affect performance. Generally, lower string tensions provide more power, while higher tensions offer better control. However, string tension is a personal preference and can vary depending on your child’s playing style and skill level. It’s recommended to consult with a professional stringer to determine the appropriate tension based on your child’s specific needs.

Importance of Proper Technique

Alongside choosing the right racket size, it is essential to emphasise proper technique when introducing your child to tennis. Providing them with professional coaching or lessons can significantly impact their development and enjoyment of the game. Skilled instructors can guide your child in learning the correct grips, footwork, and strokes, helping them improve their overall performance and prevent injuries. Encourage your child to practice regularly and reinforce the importance of technique and form.

Long-Term Considerations

As your child grows and progresses in their tennis journey, their racket size requirements may change. It’s crucial to reassess their sizing needs periodically to ensure they are using the most suitable racket. Additionally, stay updated with the latest advancements in tennis technology, as newer racket models may provide enhanced features and performance benefits for your child’s game.


Selecting the right tennis racket size for your child is a crucial step in their development as a player. By considering their age, height, strength, and playing style, you can ensure they have a racket that fits them perfectly and enhances their performance on the court. Remember to periodically reassess their sizing needs as they grow and progress in their tennis journey.
