Which Strings Should You Use Based on Age and Playing Level

Key Points

• Choosing the Right Strings for Juniors & Adults – Key Summary Points
  Two Main Considerations: Age and Playing Level are the key factors when selecting tennis strings.
  Players Aged 15 and Under – Injury Prevention Over Performance:
  ✅ All Levels (Ages 7–15): Prioritize soft strings (multifilaments) for arm safety.
  – High-level juniors may use hybrids (soft polyester crosses like Yonex Poly Tour Air or Head Lynx Touch).
  – Full bed of soft poly is rare and only for advanced players breaking strings often.
  – Recommended tension: 40–44 lbs (rarely above 46), using thinner gauges to reduce stress.
• Players Aged 15 and Over – Two Playing Categories:
  Intermediate / Beginner Players (1–2x/week):
  – Goal is comfort and power.
  – Best setups: Full multifilament or hybrid (multi mains / poly crosses).
  – Tension: 44–50 lbs for 98–100 sq in rackets; 48–56 lbs for oversized (100–116 sq in) frames.
  Performance / Advanced Players (frequent play + tournaments):
  – Risk of overuse injuries due to high volume. Two key options:
  – Full Polyester Bed: For control, with softer poly for injury-prone players, stiffer poly for heavy hitters.
  – Hybrid with Natural Gut: Gut in mains for power and softness, poly in crosses for durability.
  – Great for comfort and injury management; lasts long if strung professionally.
  – Cost: $50–$60 for full poly; $80+ for gut hybrid.
• Final Takeaway:
  Under 15 = prioritize safety → multis or soft hybrids.
  15+ = customize based on training load, playing style, and injury history.
  Natural gut hybrids are ideal for elite players needing comfort without sacrificing performance.
