The string in your racket affects more than feel. It can change how much power you get, how comfortable the racket feels on your arm, how long the strings last, and how confidently you can swing at the ball. Choosing the right type is one of the simplest ways to tailor a racket to your game.
The main tennis string types are natural gut, multifilament, synthetic gut, and polyester. Each has a different balance of comfort, control, durability, and price. Here’s how they compare, plus several specific strings worth considering.
The Main Types of Tennis Strings
Natural gut
Natural gut is made from animal intestine and is known for its comfort, power, and ability to hold tension. It stretches and returns energy efficiently, which can make it easier to get depth without swinging harder. Players with arm sensitivity often find it more forgiving than polyester.
The drawbacks are price and weather sensitivity. Natural gut is usually the most expensive option, and moisture can shorten its life. It can also fray before it snaps, so check it regularly. It’s a strong choice for players who value feel, or as part of a hybrid setup.
Multifilament
Multifilament strings bundle many fine fibers together to create a softer feel. They offer some of the comfort and power of natural gut at a lower price, making them a popular option for recreational players and anyone seeking a gentler setup.
They generally feel livelier than polyester, but may fray or break sooner for players who hit with heavy topspin. If you want a comfortable full bed without paying for natural gut, start here.
Synthetic gut
Synthetic gut is usually a solid nylon core wrapped in thinner fibers. It is an affordable, sensible all-around string: reasonably comfortable, easy to play with, and often available in many gauges and colors. It may not match natural gut or premium multifilament for softness, but it’s a useful baseline for players who don’t have a strong preference yet.
Polyester
Polyester, often called poly, is a firmer string commonly chosen by players who swing fast and create their own power. Its relatively low-powered response can help big hitters keep aggressive shots inside the court. Many players also like its crisp feel and the way the strings move and snap back during topspin strokes.
Poly is not automatically a shortcut to more spin, and its firm feel doesn’t suit everyone. It can feel harsh, especially at high tension, and it often loses playability before it breaks. Beginners, casual players, and people with arm pain should usually consider softer strings first. If you use poly, restring when it starts feeling dead rather than waiting for it to snap.
Hybrid strings
A hybrid combines two string types, often polyester in the mains and natural gut or multifilament in the crosses. Since the mains have a larger role in how the stringbed feels, this setup can add control while keeping more comfort than a full bed of poly. Reverse the arrangement—gut or multifilament in the mains, poly in the crosses—for a softer, livelier feel with some added control.
Hybrids let you fine-tune a racket, but the two strings may wear at different rates. If you’re unsure where to begin, ask a stringer for a modest setup change rather than making a big jump in tension or stiffness.
Quick Comparison
| String type | Typical strengths | Common trade-off | Good starting point for |
|---|---|---|---|
| Natural gut | Comfort, power, tension maintenance | High price; sensitive to moisture | Players seeking a premium, arm-friendly feel |
| Multifilament | Comfort and easy power | Can fray or break sooner | Recreational players and comfort seekers |
| Synthetic gut | Value and all-around playability | Less refined feel than premium options | New players and budget-conscious players |
| Polyester | Control for fast, full swings | Firm feel and declining playability | Experienced, frequent hitters |
| Hybrid | Mix of feel, control, and comfort | More choices to manage; uneven wear | Players fine-tuning a setup |
Six Specific Strings to Consider
These are established examples from different string categories. The best fit still depends on your racket, swing, preferred feel, and how often you play.
| String | Type and feel | Why consider it | Trade-off |
|---|---|---|---|
| Babolat VS Touch | Natural gut; soft and lively | Excellent comfort and tension maintenance; useful in a full bed or hybrid | Premium price and needs care in wet conditions |
| Tecnifibre X-One Biphase | Multifilament; cushioned and powerful | A comfortable option for players who want easy depth without a stiff stringbed | Can cost more than basic nylon and may wear quickly for heavy hitters |
| Head Velocity MLT | Multifilament; balanced response | A practical comfort-oriented choice that is often less costly than premium multifilaments | May feel less crisp or durable than a firm poly for aggressive, high-spin play |
| Prince Synthetic Gut with Duraflex | Synthetic gut; fairly direct and versatile | A straightforward, budget-friendly starting point for testing tension and gauge | Doesn’t provide the plush feel of gut or the firm control of poly |
| Solinco Hyper-G | Polyester; firm, control-focused feel | Popular with players who take full cuts and want a predictable response | May be too stiff for slower swings or sensitive arms; replace when it goes dead |
| Luxilon ALU Power | Polyester; crisp and controlled | A well-known option for advanced players who supply their own pace | Relatively firm and can lose its lively feel with use |
How to Choose the Right String
Start with your own ball flight and comfort, not a pro’s racket. If your shots land short and your arm feels fine, a more powerful multifilament or natural gut might help. If you already hit hard and often miss long, a polyester setup may offer a more controlled response—but it won’t fix technique or guarantee more spin.
String tension matters, too. Lower tension generally gives the stringbed a livelier feel, while higher tension can feel firmer and more controlled. The effect varies by string and racket, so change tension in small steps—around 2 to 3 pounds at a time—and keep notes after each restring. A softer string at a moderate tension is often a better first test than a very tight, stiff setup.
Gauge is the string’s thickness. Thinner strings can feel livelier and may offer more bite, but they usually break sooner. Thicker strings tend to last longer. Many players can begin with a common middle gauge, then adjust based on comfort and breakage.
For a simple starting guide: try synthetic gut if you’re new to string choices, multifilament if comfort is the priority, and polyester only if you swing fast enough to benefit from its firmer response. If you break strings often but still want comfort, ask about a hybrid.
Frequently Asked Questions
Which tennis string is best for beginners?
Synthetic gut or multifilament is a sensible first choice. Both are easier on the arm than a full bed of polyester. Synthetic gut is usually the budget-friendly option; multifilament tends to feel softer.
Are polyester strings bad for your arm?
Not for everyone, but polyester is firm and can feel uncomfortable, especially at high tension or when it has gone dead. If you have arm pain, consider a softer string and talk with a qualified coach or health professional about your setup.
How often should I restring my tennis racket?
There’s no single schedule for every player. Frequent hitters may need to restring often, while casual players may go much longer. With polyester, pay attention to feel and control as well as breakage, since it can lose playability before it snaps.
Is a hybrid better than a full bed of one string?
It depends on what you want. A hybrid can balance comfort and control, but it is not automatically better. Try one if a full bed feels too harsh, too powerful, or too short-lived.
Final Thoughts
There is no single best tennis string type for every player. Natural gut and multifilament emphasize comfort, synthetic gut offers dependable value, and polyester suits players who bring plenty of racket speed. Choose one change at a time, note how your racket feels, and use comfort and control—not brand names alone—to guide your next restring.
