What Really Changes When String Tension Goes Up or Down?
The slogan "higher for control, lower for power" does not fully explain launch angle or impact feel.
Player overview
Lower tension generally lets the string bed deflect more, while higher tension creates a firmer response. Actual depth and accuracy still emerge from swing adaptation, material, and pattern together.
Measurement guide
- First record the proportion of shots that land short, hit the net, or go long with the current setup.
- On the next string job, change only the tension by a small amount and keep the same string and gauge.
- Compare the first 30 minutes with the feel after 3 playing sessions.
Latest measurement
The effects of higher and lower tension are tendencies; confirm your own result with a controlled comparison.
