The thickness of a paddle depends on which playstyle you prefer and whether you're a control or power player. 14mm paddle (An All-Rounder): This paddle is good for players who are versatile in their playstyle. It's a good paddle for people who like to switch between aggressive shots and precise dinks. A 14mm paddle is light enough to remain nimble on the court. It also has enough power for when you need it. 16mm paddle (Power Player's Choice): The thicker 16mm is great for players who lean heavily towards power. The added thickness adds weight and density, making it potent to hit shots with less effort. This paddle also has better vibration dampening, but can struggle with control especially if you're not skilled enough to handle the swing weight. The 16mm paddle is the most preferred paddle for a large majority of advanced players.
