Estimates only — real results vary by ±100 or more. FIDE is over-the-board, so it maps most reliably to slower play.

Why ratings differ between platforms

A "1500" is not the same everywhere. Each platform starts new players at a different rating and uses a different formula, so the same player ends up with different numbers:

These offsets shrink toward the top of the pool: a beginner sees a big gap between sites, while strong masters land close to the same number everywhere.

How this converter works

We anchor your input to a common strength estimate, then map it back out to each pool using linear relationships derived from aggregated community comparisons. It's a ballpark, not an official conversion — treat a spread of ±100 as normal. Want the deeper theory? Read how chess ratings work.

Frequently asked questions

Why is my Lichess rating higher than my Chess.com rating?

Different systems and starting points. Lichess starts at 1500 (Glicko-2) and its pool runs roughly 100–400 points higher than Chess.com for the same player — widest in rapid, narrowest in bullet.

How does online rating compare to FIDE?

FIDE is over-the-board classical/rapid, so it's only loosely comparable to online blitz or bullet. As a rough guide, FIDE is often close to your Chess.com Rapid minus ~100, but individual results vary a lot.

Are these conversions exact?

No — they're estimates from aggregated comparisons. Two players with the same rating on one site can differ by 100+ on another. Use it as a ballpark.
