Different sites like Chess.com and Lichess have slightly different rules for determining what counts as “Blitz” or “Rapid” or the other categories.
Here I tried to pull them together in one place:
| Time | FIDE | US Chess (USCF) | Chess.com | Lichess |
|---|---|---|---|---|
| Classical | >= 60 minutes | >= 25 minutes | ||
| Regular | >= 30 minutes | |||
| Quick | < 30 minutes | |||
| Rapid | < 60 minutes | >= 10 minutes | < 25 minutes | |
| Blitz | < 10 minutes | < 10 minutes | < 10 minutes | < 8 minutes |
| Bullet | < 3 minutes | < 3 minutes | ||
| UltraBullet | < 30 seconds |

Increments
To make this table simple, I did not include information about games with increment. The typical way that is calculated is based on a 40-move game. For instance, the estimated duration of a 5+3 game is (5 × 60) + (40 × 3) = 420 seconds.
