Member Calculators
- Center of Percussion (COP) calculator
- Calculate the location of the "sweet spot" on your racquet face.
- Constant-pull to Lockout converter
- This tool allows shops that have a lockout stringing machine to approximate the stringbed tension of a constant-pull machine.
- Ideal Racquet Mass Estimator
- Estimate the weight of your "ideal" racquet based on your body mass. Based on an article by Rod Cross.
- Lockout to Constant-pull converter
- This tool is for shops that have a constant-pull stringing machine, and customers who are used to having their racquets restrung on a lockout machine.
- Ounces-to-Grams Converter
- Convert ounces to grams (and vice versa).
- Parallel Axis Converter
- Calculate how the swingweight of your racquet changes as you translate the axis of rotation up and down the handle.
- Points to Centimeters/Inches converter
- Convert racquet balance expressed in points, to a measurement expressed in inches and centimeters from the butt cap to the balance point.
- Pounds to Kilograms converter
- Calculate tensions in pounds if you have only kilograms, and vice versa.
- Proportional Stringing calculator
- Precisely calculate the tension for each main and cross string for proportional (differential) stringing of any racquet.
- Racquet Comfort Estimator
- There are many reasons why certain racquets may create sensitivity in your wrist, elbow, or shoulder. This simple estimator looks at three racquet characteristics, and gives you a number you can use in comparing racquets to get a rough idea of how easy any given racquet will be on your arm.
- Racquet Mass Mover
- What happens if you already have added lead tape to your frame, but it doesn't match another frame? You can take off all the existing lead tape, and use our tools to add it back on, or you can use this new tool to see how much you need to move the old tape to achieve your desired results. A real multipurpose tool.
- Racquet Power Calculator
- Calculate the power of your racquet based on known physical characteristics. Good for comparison shopping.
- Swingweight Calculators
- Accurately calculate swingweight, twistweight, and recoil weight without a $4,000+ Babolat RDC machine -- all you need is a couple of pencils, a stopwatch, and this tool. You can even calculate both swing weight at various grip locations, and hitting weight, which you can't do on an RDC machine.
- Tension Estimator
- Calculate a remarkably accurate tension estimate for any unknown frame.
- Twistweight Estimator
- Estimate the twistweight of a frame based on two easy measurements.
