What is a tennis Elo rating?

Elo estimates a player's relative competitive strength from match results and opponent strength.

Is Elo the same as NTRP?

No. NTRP is the self-reported level on your profile. Elo is calculated from confirmed match results.

Elo estimates skill based on who you play and whether you win. Beating a stronger opponent moves your rating more than beating a weaker one.

When the lower-rated player wins, both ratings shift more dramatically. Rewarding genuine improvement.

Courtlio groups players into Bronze, Silver, Gold, and Elite tiers to keep casual and advanced players aligned.

Inactive ratings become less reliable. Regular play keeps your Elo representative of current form.
