What Is Swingweight in Tennis?

Swingweight measures how heavy a tennis racquet feels when you swing it, not just how much it weighs on a scale.

Two racquets can have the same static weight but feel completely different during a swing. That’s because swingweight depends on where the mass is located in the frame.

For example:

• Weight added near the tip of the racquet (12 o’clock) increases swingweight the most.
• Weight added at 3 and 9 o’clock improves stability and resistance to twisting.
• Weight added in the handle changes the balance but has very little impact on swingweight.

This is why many professional players and racquet technicians customize frames with lead tape in specific locations, rather than simply choosing a heavier racquet.

Understanding swingweight helps players find the right balance between:

• Power
• Stability
• Maneuverability
• Spin potential

The MPTennis Swingweight Estimator helps you quickly calculate an estimated swingweight using your racquet’s specifications. This allows you to better understand how your racquet will feel on court and how small adjustments can change its performance.

How to Use the MPTennis Swingweight Calculator

Using the swingweight calculator only takes a few steps.

1. Enter your racquet’s head size, string pattern, and length.
2. Add your current strung weight and balance point.
3. Include details like strings, overgrips, or dampeners if they apply.
4. The calculator will estimate your racquet’s swingweight and head-light balance.

Once you know your swingweight, you can experiment with customization options like adding lead tape to different parts of the racquet.

Many players are surprised to learn that just a few grams of weight in the right place can dramatically change how a racquet performs.

If you want to go further, our Racquet Customization Planner shows you exactly where to add weight to achieve more power, stability, spin, or maneuverability.

Tennis racquet swingweight is one of the most important but least understood specifications in tennis equipment.

While most players focus on total weight, swingweight determines how powerful, stable, or maneuverable a racquet feels during the swing. Even small adjustments like adding a few grams of lead tape can dramatically change a racquet’s swingweight and performance.

The MPTennis Swingweight Calculator helps players estimate their racquet’s swingweight so they can make smarter decisions about racquet selection and customization.
