Elo rating is the system used to measure a chess player’s strength based on their game results. Every player has a number, their Elo, that goes up when they beat higher-rated opponents and goes down when they lose to lower-rated ones. Invented by physicist Arpad Elo in the 1960s, the system remains the world standard, used by FIDE as well as by every major online platform.

How your rating changes after a game

The calculation rests on a simple idea: the points won or lost depend on the rating gap between the two players. Beating a much stronger opponent pays off big; beating a much weaker one earns almost nothing. Conversely, losing to a much weaker player costs a lot, while losing to a much stronger one costs very little.

Concretely, two players of equal strength (same Elo) facing each other are playing a 50/50 match: the winner gains exactly as many points as the loser drops. The full formula also factors in the “K-factor,” a coefficient that makes ratings more volatile for young or new players and more stable for experienced ones.

Rating benchmarks

  • Under 1000: beginner, still learning the rules and the basic traps.
  • 1200-1400: casual club player, knows elementary tactics.
  • 1600-1800: solid player, comfortable with opening principles and common endgames.
  • 2000: expert level, usually reached after years of serious practice.
  • 2200: the threshold for the Candidate Master (CM) title; FIDE Master (FM) requires 2300.
  • 2500 and above: the level generally required, along with the necessary norms, for the grandmaster title.
  • 2800 and above: the absolute summit, reached by only a handful of players in history, Magnus Carlsen among them.

FIDE rating vs online rating: two different scales

FIDE rating measures strength in long, classical-time-control games at official tournaments. Online rating (chess.com, Lichess…) is calculated separately, often from blitz or bullet games, across a different pool of players. The two numbers don’t translate directly: a player might show 1800 online and only 1500 FIDE, or the reverse, simply because the scales measure different populations and different time controls.

Both platforms actually use systems more sophisticated than Elo: Glicko at chess.com, Glicko-2 at Lichess. These variants also factor in the reliability of the rating, but the underlying principle stays the same: beating stronger players earns you more.

Frequently asked questions

What counts as a good Elo rating in chess?

It depends entirely on your point of comparison. Against the average amateur player, 1200-1400 is already solid; 1800 puts you near the top of club players. The International Master title starts around 2400, and grandmaster around 2500.

Why is my online rating different from my FIDE rating?

Because they’re two separate scales, calculated over different pools of players and different time controls. Online rating, often earned in blitz or bullet against a huge number of players, doesn’t convert directly into FIDE rating, which comes from classical-time-control games at official tournaments.

How do I gain rating points quickly?

By regularly beating opponents rated higher than you: that’s where the point gain is largest. As for lasting progress, the only real method is working on your openings, your tactics and your endgames, then playing a large number of serious, reviewed games.
