Chess Clock Guide: How to Choose a Digital Clock (2026)

The chess clock (also called a chess timer or timer) is an essential instrument for any official game. It guarantees fair play by limiting each player’s thinking time. Whether you’re playing a 3-minute blitz or a 2-hour classical game, understanding time controls and choosing the right clock will make all the difference to your play.

Why use a chess clock?

Without a time limit, a player in a losing position could think indefinitely. The clock solves this problem by giving each player an identical time allowance. When a player makes their move, they press their clock button, which stops their own clock and starts their opponent’s. A player who runs out of time loses the game on time.

Official time controls

Time control	Time per player	Character	Use
Bullet	1 to 2 minutes	Ultra-fast, pure reflexes	Mainly online
Blitz	3 to 5 minutes	Fast, intuitive	Clubs, online, tournaments
Rapid	15 to 60 minutes	Moderate thinking	FIDE rapid tournaments
Classical	60 to 120+ minutes	In-depth thinking	Official championships

FIDE regulations: In classical time controls, the standard is 90 minutes for the first 40 moves, then 30 minutes for the rest of the game, with a 30-second increment per move from the very first move.

The increment: a safeguard against time trouble

The increment (or addition) is a time bonus added after each move played. For example, in a “3+2” time control, each player starts with 3 minutes and receives an extra 2 seconds after every move. This system, introduced by Bobby Fischer (hence the name “Fischer increment”), stops games being decided purely by speed of execution towards the end.

Advice for beginners: For your first club games, choose the 15+10 time control (15 minutes plus a 10-second increment). It gives you enough time to think without the game running on too long. It’s the ideal time control for improving your game.

FIDE approval: which models should you choose?

For official tournaments, the clock must be FIDE-approved. The benchmark models are the DGT 2010 (the most widely used in international tournaments), the DGT 3000 (larger screen) and the Leap KK9908 (affordable option). These clocks all handle Fischer and Bronstein time controls, as well as multi-period controls.
