How to Use This Calculator
  1. Enter String Type, Basic Nylon, and Multifilament.
  2. Set Titanium-coated, BG65-type (all-round), and BG80-type (high repulsion).
  3. Adjust Skill Level, Beginner as needed.
  4. Review the Recommended tension (lbs) result.
  5. Use Recommended tension (kg) and Recommended gauge (mm) to inform your decision.

What each input means

String Type
Type of badminton string.
Skill Level
Your badminton skill level.
Sessions per week
Number of playing sessions per week.
Avg session length (hrs)
Average playing time per session in hours.
Shuttle Type
Type of shuttlecock used.
Smash-heavy style?
Set to 1 if you hit lots of power smashes. Affects tension and string life.

What each result means

Recommended tension (lbs)
Optimal string tension in pounds.
Recommended tension (kg)
Same tension in kilograms.
Recommended gauge (mm)
String thickness recommendation balancing feel and durability.
String life (play hours)
Estimated hours of play before strings lose significant performance.
Weeks until restring
Based on your playing frequency.
Restrings per year
Estimated number of restrings needed annually.
Annual string cost ($)
Estimated annual cost for strings and labor.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    String Type = 4, Skill Level = 2, Sessions per week = 3, Avg session length (hrs) = 1.5 = 6 input(s) provided
  2. Calculate Recommended tension
    Recommended tension = max(20, min(33, baseTension + typeAdj + shuttleAdj + smashAdj))
    24 = 24
  3. Calculate Recommended tension
    Recommended tension = round(recommendedLbs * 0.4536 * 10) / 10
    10.9 = 10.9
  4. Calculate Recommended gauge
    0.68 = 0.68
