Checkers has adjusted its Elo system over time. I believe that it now matches chess except with a floor of a 1000 rating. From http://icheckers.net/ratings/, the current ratings range goes from 1000 to 2297 among active players, and up to 2510 among inactive players.

Even if you use the larger range of inactive players, that's a range of 7.5 times the standard deviation. Which is considerably less than chess.
