Elo ratings

Parent Previous Next

Chess players are given a chess rating to gauge how strong they are at chess. The standard rating system used in chess is called Elo ratings named after Arpad Elo. A related system is used in tennis, football and many other sports.

Elo ratings are based on the results of games and ratings of opponents played. The Elo rating system ranges from 1000 Elo (a complete novice) to 2800 Elo and beyond for the strongest players of all time.

Were a player A to score two points for every one point of player B, then player A would be expected from this performance to have an Elo rating about 120 Elo points more than player B. As you can see there is a great difference in chess strength as you go up the ratings.

The ratings can be split into the following broad classes:
