ITF World Tennis Number

The ITF World Tennis Number (WTN) is a numerical rating system that measures a player's skill level, ranging from 1 (elite) to 100 (beginners). It’s designed to help players find suitable opponents and organize matches based on comparable abilities. The WTN is calculated using match results, taking into account factors like opposition strength and match outcomes, which ensures an accurate reflection of current skill. This system aims to promote fair and competitive play globally, encouraging players of similar levels to compete, improve, and enjoy the game more effectively.
