Size Guide

Choose the right Grip

The grip size refers to the circumference of the handle. The circumference is measured in two units and both are listed on the racket. The first is the European “L” measuring system. The latter is the imperial system, measured in inches.

There are six different grip sizes available for adult tennis rackets. Keep in mind not all rackets are made available in every grip size.

At Rackets & Runners we like to fit our rackets by having the player grip the handle of the racket with an eastern grip (think of holding a hammer or frying pan). From there we are looking to achieve about a finger’s width between the tips of players fingers and the palm of the hand.

If you cannot visit our store or have access to a racket to measure yourself, but have access to a ruler, no need to worry. Open your dominant hand with your fingers pressed together, and measure from the tip of your ring finger to the middle horizontal crease of your palm in inches. This measurement will correspond to your grip size.

If you are between grip sizes, we always recommend going slightly smaller as it is much easier to build up a grip size than it is to decrease one.

Details

The Extreme Pro 2026 delivers the power and spin tournament players demand with the stability they need to control it. This tennis racquet combines an open 16x19 string pattern with strategic material engineering to generate heavy spin without sacrificing feel.

Hy-Bor reinforcement in the shaft maximizes perceived stability through the hitting zone. This aerospace-grade material anchors each shot with a solid impact feel. You maintain control even when you increase the pace. Auxetic 2.0 technology keeps you connected to the ball throughout the stroke, letting you sense exactly where contact happens on the string bed.

Spin Grommets work with the open string pattern to let the strings snap back faster after ball contact. The result: more revolutions per stroke. Sound Grommets deliver the crisp acoustic feedback that defines the Extreme series. At 305 grams, the Extreme Pro plows through incoming pace and gives you the mass to redirect heavy balls with confidence.

Built for competitive players who create their own offense with spin and power. The Extreme Pro 2026 gives you the tools to dictate points from the baseline.

- 16x19 open string pattern for spin generation
- Hy-Bor shaft reinforcement for stability
- Auxetic 2.0 for enhanced ball connection
- 305g weight for plow-through on heavy balls
- Spin Grommets and Sound Grommets for feel and performance
