3U vs 4U Badminton Racquet: How to Choose for the Whole Rally
Choosing between 3U and 4U? This original animated guide explains how to compare the exact model, understand weight, balance and swingweight, match strings and grip, and judge preparation, placement and sustained effort through a rally.
The ASTROX 88 D PRO example uses Yonex's model-specific official averages: 3U 88 g and 4U 83 g. These are not our measurements of finished playing racquets. Diagrams and court situations are illustrative, not recorded tests or performance results.
