What Is Elo Rating in Chess?
The Elo rating system is the standard way to measure chess strength — a number that rises when you beat stronger players and falls when you lose to weaker ones.
Definition
The Elo rating system, developed by Arpad Elo in the 1960s, assigns each player a numerical rating that reflects their relative strength. When you beat a higher-rated player, you gain more points; beats against lower-rated players earn fewer. The system is self-correcting: as your true strength improves, your rating converges on the correct number over many games. FIDE uses it for classical chess; online platforms have their own adapted versions.
Example
A player rated 1500 beats someone rated 1700. The rating difference suggests they were expected to lose — so the 1500 gains more points than they would for beating another 1500. The expected score formula means big upsets yield big rating gains.
Why It Matters for Your Chess
Your rating is a useful (though imperfect) measure of progress. Focus on improvement, not rating — but the rating is a convenient benchmark for which openings, tactics, and endgame concepts to study for your current level.
Frequently Asked Questions
What is a good chess rating?
Beginner: under 800. Intermediate: 800–1400. Club player: 1400–1800. Strong club player: 1800–2000. Expert: 2000–2200. Candidate Master: 2200+. International Master: 2400+. Grandmaster: 2500+. The world elite play above 2700.
Are online ratings the same as FIDE ratings?
No — online ratings (Chess.com, Lichess) are calibrated differently and tend to be higher than equivalent FIDE ratings. A Chess.com 1500 rapid rating is typically closer to 1000–1100 FIDE. Lichess ratings are often closer to FIDE than Chess.com ratings.

Initiative
The initiative is the ability to make threats that must be answered — the player with the initiative dictates the pace and direction of play.
Compensation
Compensation is the non-material advantage — initiative, activity, pawn structure, king safety — that offsets being down in material.
Endgame
The endgame is the final phase of the chess game — when queens (and often other pieces) are off the board and king activity becomes decisive.
Tactic
A tactic is a sequence of forced moves that immediately wins material or delivers checkmate — the short-term 'violence' of chess.
