What side of the board does the chess clock go on?
The clock goes on Black’s right-hand side, which is White’s left, with the buttons facing along the edge of the table. So when someone asks what side of the board does the chess clock go on at a club night or a weekend open, that is the answer you will see on nearly every board in the hall. Because the board is set up with a light square in each player’s near-right corner, Black’s right is the a-file end.
It is a convention rather than a law of the game. No rule fixes a side. Under the FIDE Laws of Chess, Article 6.5, the arbiter decides where the clock is placed before the game starts, and most arbiters simply follow the same tradition down every row. Under US Chess rules the director may set the placement; where the director leaves it to the players, the choice belongs to Black.
What side of the board does the chess clock go on in a rated tournament?
Three rules cover it, and they stack in this order:
- The arbiter or tournament director outranks everyone. If clocks are already laid out on the tables, leave them alone. Uniform rows let an arbiter walk an aisle and read forty displays without leaning over anybody.
- Otherwise Black chooses. Black picks the side, and by habit almost always picks the right.
- If Black is not at the board when the round begins, White may set it up. The player who is present gets on with it rather than waiting, and Black takes the position as found.
| Situation | Who decides where the clock goes |
|---|---|
| Clocks pre-placed by the organiser | The organiser, and it stays put |
| Standard game, both players present | Black |
| Black not at the board when the round begins | White, subject to the director |
| A dispute of any kind | The arbiter or tournament director |
Why Black gets the choice, and why it is the right
Black moves second, which is a small structural disadvantage, so the tradition hands Black a small compensating privilege: the choice of equipment and the choice of where the clock sits. It costs White nothing and it settles an argument before one starts.
You will hear various origin stories for the right-hand default, usually involving scoresheets and elbows. None of them trace to a documented source, so treat them as club lore rather than history. What can be said plainly is that most players are right-handed, and putting the clock on Black’s right puts the button under the stronger hand of the player who did not get the first move.
The side also shapes the physical motion of a move, because Article 6.2.3 of the FIDE Laws requires a player to press the clock with the same hand that made the move. You cannot move with one hand and punch the clock with the other to save a fraction of a second. Our guide on which hand you press the chess clock with goes into that.
Chess clock placement when a player is left-handed
A left-handed player may ask for the clock to be moved, and it is normal to agree. Work out who is actually inconvenienced before you argue about it. With the clock on Black’s right, a left-handed Black is the one reaching across the board on every move, because the same-hand rule means the reach has to be made with the hand that just moved a piece. A left-handed White, by contrast, has the clock conveniently on the left already. Flipping the clock to Black’s left solves the first problem and creates the second.
Two things decide the answer. First, both players must be able to reach their own button comfortably without standing up or stretching over pieces. Second, the clock must not block either player’s view of the board or of the opponent. A tall digital clock parked in front of a shorter player is a real problem, whatever side it is on. Ask before the game begins, not on move twenty.
Where it never goes. Not between the players on the long axis of the table, not behind either player, and not on a stack of books. It sits flat on the table beside the board, facing along the table edge so both displays are readable from either seat.
What to do when your opponent objects
Objections usually come from one of three places, and each has a simple answer.
- “I always have it on my right.” If you are White, that is not your call. Set it on Black’s right and move on.
- “It is blocking my view.” Legitimate. Slide it a few centimetres further from the board, or angle it. If that fails, call the arbiter.
- “You already started, you cannot move it now.” Correct in spirit. Settle placement before White’s clock is started; after that, only the arbiter should be moving anything.
The broader etiquette around starting, pressing and stopping is set out in our summary of the chess clock rules.
Where does the chess clock go when it is a phone or tablet?
A digital clock app changes the geometry completely. The device lies flat between the two players, in the middle of the long edge of the table, roughly where a physical clock would sit but turned so the screen faces up rather than sideways. Each player taps their own half of the screen, so there is no left or right question to settle: neither half belongs to a side of the board.
What matters instead is orientation. The half nearest White faces White; the half nearest Black is upside down unless the app rotates it. That is why the top half of the chess clock on the front page is rotated 180 degrees, so the player on the far side reads their own time the right way up and taps the zone directly in front of them. The Chess Timer app on the App Store and Google Play uses the same two tap zones and runs Fischer increment controls.
Two practical notes for phone clocks. Put the device where neither player’s sleeve will sweep it while reaching for a piece, and turn the brightness up, because a dim phone at arm’s length is unreadable mid-scramble.
Setup advice for club organisers
If you run a club night, place the clocks yourself before anyone arrives. It removes an entire class of small disputes, and it takes one pass down the row.
- Put every clock on Black’s right, all facing the same way down each row, so you can read a whole aisle at a glance.
- Set the time control on every clock before the round, not board by board once players are seated.
- Keep two or three spare clocks and a pack of batteries by the desk.
- Say out loud that a left-handed player may ask to move the clock and that opponents should agree. New players do not know they are allowed to ask.
- Leave a gap between boards. Most placement complaints are really complaints about elbow room.
Set your clock down and start playing
Place it on Black’s right, check that both of you can reach your own button and see the board, and start White’s clock. Settle any objection now, while the position is still the starting position and nobody has a result to protect.
