A complete tactical framework for players with below-average height, leveraging the natural advantages of a lower center of gravity while mitigating the disadvantage of less reach. Shorter players have natural advantages that taller players spend their career trying to replicate.
Relinquish some kitchen line position — stand slightly further back to get more time for dinks and reduce lob vulnerability. You lose some volley dink opportunities but gain: better depth perception on dinks, more time to react, less lob vulnerability, and more room for your partner to intercept. Use slice on cross-court dinks — shorter players can naturally slide the paddle under the ball more easily than tall players who must bend. Athletic position with knees bent, feet wider than shoulder width. Expect and prepare for lobs — get into the most athletic position. For overheads: push off lead foot into cross step, coil upper body, trophy position, tilted throwing motion.
Shorter players are naturally in the body position that taller players spend their careers trying to achieve. Lower center of gravity = better dinking height, easier slice execution (paddle slides under the ball naturally), more agility, and potentially better endurance. The "disadvantage" is actually a built-in toolkit.
