Tennis Strings: Complete Guide to Types, Tension & Best Picks (2026)
Your tennis strings have more impact on your game than almost any other piece of equipment — more than your racket frame, more than your shoes, and far more than most players realise. The right tennis string can add spin, power, control, or comfort to your game. The wrong one can cause arm pain, reduce your feel, and hold back your development. This complete guide covers everything you need to know about tennis strings: types, materials, tension, gauge, and the best picks for every level in 2026.

Most recreational players focus on their racket frame and ignore their tennis strings — but string choice is arguably more important. The strings are the only part of the racket that actually contacts the ball. They determine:
- Power: How much energy is transferred to the ball on contact
- Spin: How much the strings grip and release the ball to generate topspin or slice
- Control: How precisely you can direct the ball
- Comfort: How much shock and vibration reaches your arm
- Feel: How connected you feel to the ball at contact
Changing your tennis strings is the single most cost-effective upgrade most players can make to their equipment.
Tennis String Types: The Complete Guide
Natural Gut — Best Feel & Comfort
Natural gut is made from cow intestine and is the original tennis string — used since the sport began. It remains the gold standard for feel, power, and arm comfort. Natural gut maintains tension better than any synthetic string, provides exceptional elasticity, and is the most arm-friendly option available.
Best for: Players with arm problems, players who prioritise feel and power, advanced players who can afford premium strings.
Downside: Expensive (€30–50 per set), not durable in wet conditions, breaks faster than synthetic strings.
Polyester (Poly) — Best for Spin & Control
Polyester tennis strings are the most popular choice among competitive and advanced players. They’re stiff, durable, and — when strung at lower tensions — generate exceptional spin through the “snap-back” effect where the strings move and return to position during contact.
Best for: Intermediate to advanced players with full swings, baseline players who hit heavy topspin, players who break strings frequently.
Downside: Stiff and arm-unfriendly at high tensions, loses tension quickly (restring every 20–30 hours of play), not recommended for beginners or players with arm issues.
Multifilament — Best Synthetic Alternative to Natural Gut
Multifilament tennis strings are made from hundreds of micro-fibres woven together to mimic the feel of natural gut at a lower price point. They’re soft, arm-friendly, and provide excellent power and feel. The best multifilament strings are almost indistinguishable from natural gut for recreational players.
Best for: Beginners, recreational players, players with arm problems, players who want natural gut feel at a lower price.
Downside: Less durable than polyester, less spin potential than poly strings.
Synthetic Gut — Best Value for Beginners
Synthetic gut is the most affordable tennis string option — a single nylon core with a braided outer wrap. It’s the string that comes pre-installed in most beginner rackets. It’s decent for recreational play but outperformed by multifilament strings in almost every category.
Best for: Complete beginners, players on a tight budget, casual recreational players.
Downside: Average feel, average durability, average everything — a stepping stone rather than a destination.
Hybrid Stringing — Best of Both Worlds
Hybrid stringing uses two different tennis strings — typically natural gut or multifilament in the mains (vertical strings) and polyester in the crosses (horizontal strings). This is the setup used by Roger Federer throughout his career (natural gut mains, Luxilon poly crosses) and many top professionals.
Best for: Advanced players who want spin and durability from poly crosses with the feel and comfort of natural gut mains.
Downside: More expensive than a full set of either string, requires a knowledgeable stringer.

Tennis String Tension: What You Need to Know
Tennis string tension is measured in pounds (lbs) or kilograms (kg) and has a major impact on how your racket plays. Most rackets are strung between 45–65 lbs (20–29 kg).
Lower Tension = More Power, Less Control
Lower tension creates a larger “trampoline effect” — the strings deflect more on contact and spring back, adding power. Lower tension also reduces shock to the arm. Most polyester strings perform best at lower tensions (40–50 lbs) where the snap-back effect generates maximum spin.
Higher Tension = More Control, Less Power
Higher tension reduces string deflection, giving you more control over ball placement. Advanced players with fast swing speeds often prefer higher tensions because they generate their own power and need the control that tighter strings provide.
Recommended Tensions by Level
| Level | Recommended Tension | String Type |
|---|---|---|
| Beginner | 50–55 lbs | Synthetic gut or multifilament |
| Intermediate | 48–55 lbs | Multifilament or poly |
| Advanced | 45–55 lbs (poly), 55–62 lbs (gut) | Poly, hybrid, or natural gut |
Tennis String Gauge: Thickness Explained
Tennis string gauge refers to the thickness of the string. Thinner strings generate more spin and feel but break faster. Thicker strings are more durable but less responsive.
- 15 gauge (1.41–1.49 mm): Thickest — most durable, least spin and feel
- 16 gauge (1.26–1.34 mm): Good balance of durability and performance — most popular for recreational players
- 17 gauge (1.20–1.24 mm): Thinner — more spin and feel, less durable
- 18 gauge (1.10–1.16 mm): Thinnest — maximum spin and feel, breaks quickly

When to Restring Your Tennis Racket
The general rule for restringing is: restring as many times per year as you play per week. If you play 3 times per week, restring 3 times per year. Signs your tennis strings need replacing:
- Strings feel dead or flat — no pop or response on contact
- Ball control has deteriorated noticeably
- Strings have moved and won’t realign
- Visible fraying or notching on the strings
- It’s been more than 3 months since your last restring (even without breaking)

Frequently Asked Questions: Tennis Strings
What are the best tennis strings for beginners?
The best tennis strings for beginners are multifilament strings or synthetic gut. They’re arm-friendly, provide good power and feel, and are affordable. Avoid polyester strings as a beginner — they’re stiff, arm-unfriendly, and require a fast swing speed to perform well. Browse beginner-friendly tennis strings on Amazon →
What tennis strings do the pros use?
Most professional players use polyester tennis strings or hybrid setups. Nadal uses Babolat RPM Blast (full poly). Djokovic uses Babolat VS Natural Gut mains with Luxilon ALU Power crosses (hybrid). Federer used Wilson Natural Gut mains with Luxilon ALU Power crosses throughout his career.
How often should I restring my tennis racket?
Restring as many times per year as you play per week. If you play twice a week, restring twice a year. If you play daily, restring every 1–2 months. Even if your tennis strings haven’t broken, they lose tension and elasticity over time and should be replaced regularly.
What tension should I string my tennis racket?
Most recreational players perform best between 50–55 lbs. Lower tension (45–50 lbs) adds power and is better for arm comfort. Higher tension (55–62 lbs) adds control for players with fast swing speeds. Always stay within the tension range recommended by your racket manufacturer.
Are polyester strings bad for your arm?
Polyester tennis strings strung at high tension can contribute to arm problems — particularly tennis elbow — because they’re stiff and transmit more shock to the arm. If you have arm issues, switch to multifilament or natural gut strings at a lower tension. See our guide on tennis elbow causes and treatment →
