Your strings are the only part of your racquet that touches the ball. They affect power, spin, comfort, and control more than any other equipment choice. This guide covers everything you need to know.
Made from cow intestine fibers. The most comfortable, powerful, and tension-stable string available. Used by pros who need feel and arm protection. Expensive at around 40-55 dollars per set and less durable against heavy topspin.
A stiff monofilament string and the tour standard for spin and control. Available in round and shaped profiles. Shaped versions with square, pentagon, or octagonal cross-sections grip the ball more for extra spin. Best for advanced players with fast swings. Harsh on the arm.
Hundreds of microfibers wrapped together to mimic natural gut at a lower price. Comfortable, powerful, and arm-friendly. The best choice for most recreational players.
A basic nylon string with a solid core. Affordable at 6-10 dollars per set, balanced, and predictable. The best entry-level option. Most pre-strung racquets use synthetic gut.
Two different strings in the same racquet. Typically polyester mains for spin and control with natural gut or multifilament crosses for comfort and power. The most versatile setup available.
| Gauge | Diameter | Characteristics |
|---|---|---|
| 15L (thickest) | 1.35mm | Most durable, least feel, least spin |
| 16 | 1.30mm | Good balance of durability and performance |
| 16L | 1.25mm | Popular choice with more feel and spin than 16 |
| 17 | 1.20mm | More spin and feel, less durable |
| 18 (thinnest) | 1.15mm | Maximum feel and spin, breaks fastest |
Thinner strings move more, creating more spin and better feel. Thicker strings last longer. Most players settle on 16 or 16L gauge.
The right string depends on your level, racquet, playing style, arm health, and priorities. Rather than trial and error which gets expensive at 15-50 dollars per restring, use a data-driven approach.
