Choose the two strings you want to compare. Comparison automatically appears when you change either string. Differences between strings are all shown as the percentage difference of string 2 to string 1.
A tennis string comparison tool comparing string on lab tested performance criteria like power, energy return, stiffness, softness, control, comfort, shock, inter-string friction, ball-to-string friction and spin potential.
A tennis string comparison tool allowing the user to design reports on string stiffness, energy return, tension loss, peak impact force, impact tension increase, dwell time, deflection, etc., for user-defined impact conditions including string tension and swing speed.
The number of tennis strings on the market is staggering. With new strings popping up every year, the consumer is left to choose between a dizzying array of materials, features, gauges and technologies. The good news is that if you are searching for a string in 2021 you don’t have to sweat the small stuff. We’ve got you covered.
The String Comparison Tool compares any two strings on all the important properties that determine performance: material, stiffness, tension loss, energy return, spin potential, string-to-string friction, and string-to-ball friction.

However, with more than a handful of polyester strings on the market, one string stands out as the best tennis string for topspin, and that’s Babolat RPM Blast. Babolat RPM Blast First, as a polyester tennis string, the strings are slick and quickly snap back into place upon contact, helping to generate topspin.
What Is Power Potential? A racquet's power potential is determined in the lab by measuring ball velocities and calculating the ratio of the ball's outgoing bounce speed to its impact speed.
A higher string stiffness means more control, less power, and less comfort. Stiffer strings exhibit higher peak impact tension, higher peak force, less string deflection, and shorter dwell time (time on the strings). This leads to less power because the higher force crushes the ball more and loses energy.
The analysis is based on an incident ball speed of 25 mph with spin of 3,000 rpm and hit at the top of the bounce, a swing angle of 19 degrees upward from horizontal, and racquet tilt of 10 degrees forward from vertical. The impact point is 21 inches from the butt end and either on-center or 2 inches off-center.
