01
US Chess (USCF)
Official · Over-the-board
The official rating system of US Chess, the governing body for chess in the United States. USCF ratings are calculated using an Elo-based formula and updated after every rated over-the-board event. Ranges from around 100 (absolute beginner) to 2800+ (grandmaster level).
On ChessMate: A valid, non-expired US Chess membership is required to play in rated events. ChessMate checks your membership status automatically.
02
FIDE
Official · International
FIDE (Fédération Internationale des Échecs) is the world chess federation. FIDE ratings are used in international competitions and title norms (FM, IM, GM). Only FIDE-rated events contribute to your FIDE rating. FIDE lists are published monthly.
On ChessMate: ChessMate displays your FIDE rating from your public profile. FIDE title badges (FM, IM, GM, WGM, etc.) appear on your player page.
03
Chess.com
Online · Unofficial
Chess.com uses a Glicko-based system with separate ratings for Bullet, Blitz, Rapid, and Daily chess. Online ratings typically run 100–300 points higher than equivalent over-the-board ratings due to different player pools and time controls. Informational only on ChessMate.
On ChessMate: Link your Chess.com username in account settings. Your rapid or blitz rating will be displayed on your public ChessMate profile.
04
Lichess
Online · Open source · Unofficial
Lichess uses the Glicko-2 rating system, considered technically superior to Elo and Glicko-1. Lichess ratings tend to be provisionally inflated for new accounts and stabilize around 1500 for average club players. Like Chess.com, Lichess ratings are informational on ChessMate.
On ChessMate: Link your Lichess username in account settings. Your classical or rapid rating is displayed on your ChessMate profile.
01
Section eligibility
Directors use your USCF rating to enforce section limits (e.g. U1800 sections). ChessMate checks your rating automatically when you attempt to register.
02
Swiss pairing seeds
In Swiss tournaments, initial pairings are seeded by USCF rating. Higher-rated players are paired in the top half of their score group.
03
Public profiles
All four ratings appear on your public player profile so opponents, coaches, and spectators can see your full rating picture at a glance.
04
Membership enforcement
For rated events, ChessMate verifies your US Chess membership is active. An expired membership blocks registration and shows a warning on your dashboard.
