Formula Used
Center point: racquet length ÷ 2.
Balance points: absolute balance difference from center ÷ 0.3175 cm.
New balance: (W × B + m1 × d1 + m2 × d2) ÷ (W + m1 + m2).
Static moment: weight × balance point.
Torque: (weight in kg) × 9.80665 × (balance in meters).
Swingweight change: added mass in kg × distance from pivot squared.
Mass for target balance: W × (T − B) ÷ (D − T).
Total project cost: material cost plus service cost for all racquets.

Tennis Racquet Balance Guide
Why Balance Matters
Racquet balance explains where the frame feels heavy. A lower balance point places more mass toward the handle. This setup feels quicker during volleys, returns, and defensive swings. A higher balance point places more mass toward the head. It can increase plow through and power, but it may feel slower.
A balance number alone does not describe the whole frame. Static weight, length, swingweight, grip weight, strings, dampeners, and overgrips all change feel. This calculator helps you connect those values. It shows the balance point, balance percentage, head light or head heavy points, and static moment.
Using Balance Points
Tennis players often describe balance with points. One point equals one eighth of an inch from the center of the racquet. If the balance point is closer to the handle than the center, the frame is head light. If it is closer to the head, the frame is head heavy. Even small changes can matter, because added mass changes both total weight and balance.
Customization Planning
Lead tape, tungsten tape, silicone, leather grips, and overgrips are common tuning tools. Adding weight near the tip usually raises balance and swing feel. Adding weight near the handle usually lowers balance and improves maneuverability. This page estimates the new balance by using weighted averages. It also estimates the mass needed at one location to reach a target balance.
Practical Setup Advice
Use a ruler, balance board, or dowel to measure from the butt cap to the balancing point. Enter strung measurements when possible, because strings affect real playing feel. Save each test result before changing hardware. Compare several plans using the example table. Make small changes first. Then test on court with the same ball type and string tension.
Recordkeeping Helps
Keep one record for each frame. Note strings, tension, grip build, dampener weight, and tape position. These notes make repeat matching easier. They also show which changes actually improved control, comfort, or depth during regular hitting over time.
Finance Category Note
This tool can support buying and customization decisions. It helps compare frames before paying for matching services, tape, grips, or professional tuning. Clear balance records reduce wasted purchases and make setup changes easier to justify.
FAQs
What is tennis racquet balance?
It is the point where the racquet balances from the butt cap. It shows whether mass feels closer to the handle or the head.
What does head light mean?
Head light means the balance point is closer to the handle than the center. These racquets usually feel easier to swing quickly.
What does head heavy mean?
Head heavy means the balance point is closer to the racquet head than the center. It can add power but may reduce maneuverability.
How many centimeters are in one balance point?
One balance point equals one eighth of an inch. That is 0.3175 centimeters. The calculator uses this value for points.
Can I plan lead tape changes?
Yes. Enter added mass and its location from the butt cap. The calculator estimates new weight, balance, and swingweight change.
Why add weight near the handle?
Handle weight can lower the balance point. It can make the racquet feel more head light while increasing total static weight.
Why add weight near the tip?
Tip weight raises balance and swingweight more strongly. It may improve depth and stability, but it can make swings slower.
Is the swingweight result exact?
It is an estimate based on added mass and distance from the pivot. Use a proper measuring device for official matching.
