Tennis Racket Swing Weight Calculator
🎾 Tennis Racket Swing Weight Calculator
Estimate swing weight, balance shift, and final mass after lead tape, strings, or handle tuning.
Use the unit toggle, then compare where extra mass sits on the racket: tip, hoop, strings, or handle.
📍 Presets
⚙ Swing Weight Inputs
Show masses in grams and balance in cm from the butt cap.
Use the measured strung weight before any new customization.
Measure from the butt cap to the racket's balance point.
Swing weight stays in kg cm^2 no matter which unit mode you choose.
Tip weight changes swing weight the fastest of all add-ons.
Hoop mass adds stability and raises inertia near the top end.
Butt-side mass helps the frame feel more head-light in hand.
Use the added mass from the string bed and small accessories.

💡 Tips
Measure balance from the butt
Keep the ruler fixed at the butt cap so every comparison uses the same zero point.
Tip lead changes SW fastest
Mass near the tip raises inertia much more than mass in the handle.
Compare tennis racket swingweight, balance, and total mass in one place so you can tune a frame for faster handling, steadier contact, or a heavier custom feel.
Swing weight are a measurement of how a tennis racket feel when a player swings through air with the racket. Many peoples believe that the static weight of a racket is the most important measurement for players. However, swing weight is an important measurement because swing weight determine the resistance that the racket will provide for the player during their swing.
Swing weight isnt just the total weight of the racket. Instead, swing weight is the mass of the racket multiplied by the distance of that mass from the handle of the racket. If a racket has a higher mass value closer to the tip of the racket, the swing weight will be higher.
What is swing weight and why it is important
Similarly, if the mass of the racket is closer to the handle, the swing weight will be lower. The location of the mass of the racket will impact the way that the racket feel to the player. For instance, placing mass into the racket at the 12 o’clock mark will significantly increase the swing weight of the racket.
This addition mass will make the racket feel as if it is a tool with more weight behind it during the swing. Players that want to hit heavy groundstroke may prefer a racket with a high swing weight to provide more stability and more “plow through” when they swing their racket in that direction. Players that play alot at the net may want a racket with a lower swing weight so that it can move more fastly.
Rackets with a lower swing weight are more maneuverable and allow the player to react to the ball quick. The swing weight of a racket will differ for different type of players. Net rushers tend to prefer a swing weight that is below 315 points.
This swing weight allow for the quick movements of the players racket to quickly reach the ball at the net. All court players may prefer a swing weight that is between 315 and 325 points. This swing weight allows the player to have a balance between maneuverability and stability in their racket.
Finally, players that play mostly from the baseline will prefer a swing weight that is above 326 point. This swing weight will allow the racket to plow through the ball when hit with a powerful groundstroke. Lead tape is one tool that players can use to change the swing weight of their racket.
If players add lead tape to the tip of the racket, the swing weight will increase and the racket will become more head heavy. If a player adds lead tape to the 3 or 9 o’clock position on the racket, the stability of the racket will increase, but the swing weight will not increase as much. However, if the lead tape is added to the handle of the racket, the swing weight will decrease and the racket will become head light.
Because head light racquets are easier to swing and dont cause fatigue to the players arm, head light racquets are more comfortable for those players that play for long period of time. In addition to the swings of the racquets, the strings that are within the racquets also play into the balance and weight of the racquets. The strings add to the mass of the racquets, which increase the swing weight of the racquet.
Additionally, because the racquet strings are located toward the head of the racquet, they impact the balance of the racquet. When changing the swing weight of the racquets, there is tradeoffs that a player should consider. High swing weights provide more stability and control for the player when they hit the ball with the racket off-center.
However, a higher swing weight require the player to have quicker arm movements to compensate for the additional weight of the racket. Finally, a lower swing weight allow for the player to have better maneuverability with the racket. However, a lower swing weight may limit the amount of power that can be generated when swinging the racket.
Prior to changing the specifications of a racket, there are a few measurements that should be taken of that racket. The static weight of the racket can be measured with a scale. Additionally, the player can measure the balance of the racket by hanging the racket from the butt cap of the racket.
Finally, a specialized machine or an application on a digital device can measure the swing weight. After measuring the racket, changes can be made using lead tape. However, the player should test these changes on the court so that the player can feel the racket while in play.
The specifications of the racket should match the physical capability of the player with the racket for best results.
