When Swingweight Matters More Than Static Weight
Two 300g racquets can differ in preparation speed and resistance to impact when their mass is distributed differently toward the head.
Player overview
Swingweight measures rotational inertia—how difficult a racquet is to rotate—and strongly shapes the tradeoff you feel between maneuverability and stability at impact.
Measurement guide
- Compare swingweight side by side among candidates with similar static weight.
- Playtest fast returns, high balls, and serves to see whether preparation becomes late.
- Record racquet-head speed and clean-contact rate late in the session, not just power at the start.
Latest measurement
Swingweight explains the effort of actually swinging a racquet better than the feeling of simply holding it.
