What is WTN?

World Tennis Number (WTN) is a modern, data-driven tennis ranking system designed to provide more accurate and transparent player performance metrics than traditional ranking systems.

Rating Scale

WTN typically uses a numerical scale where each rating represents a specific competitive level.

The system is designed to be intuitive, allowing players to easily compare their rating to others and understand their relative skill level in the global tennis community.

One of the key advantages of WTN is its transparency. Players can see exactly how their rating is calculated and what matches or performances influenced their ranking. This openness makes WTN particularly valuable for recreational and amateur players who want to track their improvement and find appropriate competition levels.

Adoption and Growth

WTN has gained increasing adoption among tennis organizations, tournaments, and players worldwide. It complements (rather than replaces) traditional ATP and WTA rankings for professional tennis. Many tennis facilities, leagues, and coaching programs use WTN to provide players with meaningful feedback on their development and to help match players with appropriate competitive opportunities.
