Grass rewards a first serve, a confident volley and a ball that stays low. But there is no special string that makes a racket “better on grass.” The right choice depends more on your swing, comfort and preferred feel than on the court surface. A useful grass-court setup gives you predictable depth and enough control to attack without making your arm work harder than it needs to.
Because rallies can be short and the bounce unpredictable, many players want a dependable response on serves and returns. That does not automatically mean choosing the stiffest polyester string or dropping tension. Start with how you play, then make small adjustments based on what the ball does.
What matters in a grass-court string
Grass often produces a lower, less consistent bounce than a hard court, and points can move quickly. A string’s job is still the same: help you send the ball where you intend while providing a feel you can play with comfortably. Strings do not create court grip, fix late footwork or guarantee more spin, though a suitable setup can make your shots easier to control.
- Control for attacking shots: If you hit hard and want to take the ball early, a firm, controlled string may help you keep your drives and returns from sailing long.
- Comfort for frequent play: Polyester can feel firm, particularly at higher tensions. If you have arm discomfort or play several times a week, consider a multifilament, natural gut or a hybrid.
- Predictable feel at the net: A string bed that feels consistent can help with touch volleys and blocked returns. More power is not always an advantage when a short swing sends the ball long.
- Durability that suits your habits: A frequent string-breaker may need a durable polyester or hybrid. If you rarely break strings, comfort and feel may matter more than maximum lifespan.
Grass does not call for an automatic tension change. If your usual setup works on other courts, try it first. When a change is needed, adjust tension modestly and test it in practice rather than changing string and tension at once.
Five strings worth considering
These options cover different playing styles; none is the right choice for everyone. Gauge, racket pattern, tension and individual feel all affect the result. Treat any tension suggestion from a stringer as a starting point within your racket’s recommended range, not a universal prescription.
| String | Best suited to | Strengths | Trade-offs |
|---|---|---|---|
| Wilson Natural Gut | Players prioritizing comfort, feel and easy depth | Elastic response, lively feel and strong comfort | Expensive; vulnerable to moisture and less durable for frequent string-breakers |
| Luxilon ALU Power | Experienced players with fast swings | Controlled response and a firm, connected feel | Can feel harsh; playability may decline as the string loses tension |
| Babolat RPM Blast | Players who want a spin-oriented polyester | Textured profile and a controlled feel on aggressive swings | Still a firm polyester; not a cure for arm discomfort |
| Tecnifibre X-One Biphase | Players seeking a comfortable multifilament | Comfortable, lively response with good touch | Usually less durable than polyester for heavy hitters |
| Head Velocity MLT | Players wanting a practical, comfortable multifilament | More forgiving feel and a useful balance of playability and value | May fray or break sooner than a durable polyester setup |
1. Wilson Natural Gut
Natural gut is a strong option if comfort, touch and easy power matter most. On grass, that lively response can help a player serve and volley without having to swing at every ball with maximum force. It can also work well for someone who wants depth from a compact swing. The main drawbacks are cost and sensitivity to damp conditions. If you play in changeable weather, ask your stringer about protecting the string bed and consider a hybrid rather than a full bed.
2. Luxilon ALU Power
ALU Power suits a player with a long, fast swing who generates plenty of pace and wants the string bed to feel controlled. It can be appealing for aggressive baseliners who want to drive returns through the court. Its firmness is a real consideration, not a minor detail: players with elbow or shoulder concerns should be cautious, avoid excessive tension and consider a softer setup. Polyester also does not stay at its freshest indefinitely, even if it has not snapped.
3. Babolat RPM Blast
RPM Blast is a shaped polyester aimed at players who like a firm, spin-friendly response. It may suit a heavy topspin hitter who uses that spin to create a higher margin on approach shots and returns. On grass, spin can still be useful, but it is not a requirement and the court will not make this string more comfortable. If your swing is moderate or your arm is sensitive, a multifilament or hybrid is usually a safer first test.
4. Tecnifibre X-One Biphase
X-One Biphase is a multifilament option for players who want a softer, livelier feel than most polyester strings provide. It can make touch shots and volleys feel more comfortable, and suits players who do not regularly break strings. Heavy hitters may find it wears through faster, so it is not necessarily the economical choice if you restring often. It is worth considering when comfort matters more than maximum durability.
5. Head Velocity MLT
Velocity MLT offers a comfortable alternative for recreational and intermediate players who want a forgiving response without moving straight to natural gut. It can work well for an all-court game that includes serving, approaching and volleying. It may not last as long as polyester for a player who hits with heavy spin and breaks strings frequently, but many players will benefit more from a comfortable string they can use consistently.
Should you use a hybrid?
A hybrid combines two types of string, commonly a softer string in the mains and polyester in the crosses. Natural gut mains with polyester crosses are a well-known example; Roger Federer’s long-used hybrid setup helped make this kind of combination familiar to players. It can offer a blend of comfort, feel and control, but a professional’s exact setup is not a ready-made prescription for everyone.
For a club player, a gut or multifilament main with a softer polyester cross can be a sensible experiment if a full polyester bed feels too harsh. A polyester main with a multifilament cross is another option for someone who wants a firmer, more controlled feel. Hybrids can be less durable than a full polyester bed, and the two strings may wear at different rates. Ask your stringer to recommend compatible strings and tensions for your racket and playing style.
How to choose and test your setup
- Start from your current setup. If it feels comfortable and keeps the ball in, there is no need to switch just because you are playing on grass.
- Match the string to your swing and arm. Fast, full swings and frequent string-breaking can point toward polyester. A shorter swing, comfort concerns or infrequent restringing often favor multifilament or gut.
- Change one variable at a time. Test a new string at a familiar tension before changing both string and tension. Otherwise, it is hard to tell what improved—or made things worse.
- Judge more than the first hit. Pay attention to serve control, return depth, touch volleys, comfort and how the string feels after several sessions. Replace polyester if it becomes noticeably harsh or unpredictable, even if it has not broken.
Keep a simple note of the string, gauge, tension and date. If your volleys float long, you may want a more controlled setup or a small tension adjustment. If the ball feels dead and your arm is comfortable, a livelier string or slightly lower tension may help. Make changes in small steps, then test them in realistic points.
Frequently Asked Questions
Is polyester the best string for grass courts?
Not automatically. Polyester can suit strong hitters who want control, but it may feel too firm for players with shorter swings or arm sensitivity. Grass alone is not a reason to choose it.
Should I lower my tension for grass?
Only if testing suggests it would help. A lower tension can make a string bed feel livelier, but may also make depth harder to control. Begin with your usual tension and make a small adjustment if needed.
Which string is best for serve-and-volley players?
There is no single answer. A comfortable multifilament or gut can provide a lively feel and touch, while a controlled polyester may suit a player with a fast swing. Choose based on your comfort and how consistently you land serves and volleys.
Does a thicker string last longer?
Often, a thicker gauge can improve durability, but it may change feel and response. The result depends on the string, racket and your playing style, so ask your stringer about a gauge that balances lifespan with the feel you want.
Final Thoughts
The best string for grass is the one that lets you serve, return and finish points with confidence while staying comfortable. Start with a setup you already trust, then compare options such as ALU Power or RPM Blast for a firm, controlled response, and X-One Biphase, Velocity MLT or natural gut for a softer feel. Test one change at a time; a well-matched string is more useful than a surface-specific rule.
