How to Measure Your Foot
Place your foot flat on the floor against a wall. Measure the distance from the heel to the tip of your longest toe.
Always use the longer foot measurement for best fit.
Heel to Toe Length (in cm) is the most accurate way to choose your shoe size.

Sizes may vary slightly depending on foot shape and brand. This guide is for reference only.
Your racket is more than just a frame — stringing defines how it plays. The right tension improves power, control, comfort, and durability.
How String Tension Affects Play
More power • Larger sweet spot • Forgiving hits
Balanced power and control
More control • Precision shots • Smaller sweet spot
Recommended Tension by Player Level
Tension: 17–20 lbs
Power: High • Sweet Spot: Large
Tension: 20–24 lbs
Balanced power and control
Tension: 24–27 lbs
High control • Medium sweet spot
Tension: 27–30+ lbs
Very high precision • Small sweet spot
Key Considerations
- Performance: Proper tension balances power and control.
- Injury Prevention: Too much tension can strain the arm.
- Racket Safety: Never exceed the recommended tension.
- Beginners: Lower tension helps with mishits.
- Plastic Shuttles: Reduce tension by 2–3 lbs.
- String Lifespan: Depends on play frequency.
Final Recommendation
Beginners: Choose lower tension for comfort and power.
Advanced players: Higher tension gives better precision.
If unsure, always choose comfort first.
