Table Tennis Referee & Umpire Guide

The Laws of Table Tennis did not change for 2026. The ITTF Statutes 2026 — the 54th edition, in force since 1 January 2026 — carry Chapter 2 forward word for word from 2025, and amend Chapter 3, the Regulations for International Competitions, in exactly three places. Only one of the three changes anything an umpire does at the table.

One naming point first, because it causes confusion in officiating exams: the book most umpires still call "the Handbook" has been called the Statutes since the 2022 AGM decision. There is no ITTF Handbook 2026.

1. Regulation 3.3.2.8 — the TTR overrule is narrowed. In the 2025 edition, "a decision made by either the umpire or assistant umpire may be overruled by the TTR official." The 2026 text adds three limits: only a decision resulting in a point, only on a question of fact, and only in accordance with 3.2.7.1. A procedural or interpretive call is now expressly outside the review official's reach.

2. Regulation 3.2.4.5 is deleted — the glue room is gone. The clause requiring "a properly ventilated area" for attaching racket coverings, and banning liquid adhesives everywhere else in the playing venue, no longer exists. Racket control itself is untouched: testing normally happens before the match (3.2.4.2.2), a racket that fails may be swapped for a second racket rather than ending the player's day (3.2.4.2.3), voluntary pre-match testing carries no penalty (3.2.4.2.4), and four accumulated failures in four years still bring a 12-month suspension, appealable to the ITTF Tribunal within 21 days (3.2.4.3, 3.2.4.3.2).

3. Regulation 3.2.3.1 — the playing space is now a cuboid. The minimum space was previously "defined by a rectangle not less than 14m long, 7m wide and 5m high, but the 4 corners may be covered by surrounds". For 2026 it is defined by a cuboid and the corner-cutting allowance is deleted. The numbers are unchanged: 14 m × 7 m × 5 m, reduced to no less than 8 m × 6 m for wheelchair events and 10 m × 5 m for Masters events.

Who can change the Laws from now on. At its centenary AGM in London on 3 May 2026, the ITTF adopted a standalone Constitution 2026. Article 8.3 makes the Laws of Table Tennis Rules "adopted by the General Assembly"; Article 9.10 requires a three-quarters majority of votes cast to adopt or amend them; and Article 10.5 expressly bars the Council from amending them. Everything else — including Chapter 3, the regulations an umpire actually works from — remains Council business. The practical reading for officials: the next change to your working regulations will arrive as a Council decision, not an AGM vote.

One more thing worth knowing about how the book is built: the tracked-changes edition states that the 2026 Statutes implement decisions taken at the 2025 Council Meeting and AGM. Anything decided in 2026 lands in the 2027 edition, not this one.

Because Chapter 2 is untouched, the scoring arithmetic is exactly as it was — 11 points, two clear at 10-all, best of an odd number of games. Our guide to how table tennis scoring works is unchanged for 2026.

TTR is table tennis's video review, and it is the only route by which a player can overturn a match official. Regulation 3.2.7.1 provides that an electronic table tennis review system "may be used, and it will come into effect when an appeal is made by a player against a decision of a responsible match official on a question of fact". The system replays the incident and a TTR official — not the umpire — makes the final decision. Regulation 3.3.3.3 confirms it: where TTR is in operation, "the decision of the TTR official shall be final."

Read that against the two rules that normally close the door on appeals. Regulation 3.3.3.2 bars any appeal to the referee against a factual decision. Regulation 3.3.2.7 bars the umpire from overruling the assistant umpire on the calls reserved to them under 3.3.2.5 — illegal service, a service touching the net assembly, obstruction, disturbed playing conditions, and timing. TTR cuts across both: under 3.3.2.8 the TTR official may overrule either official, including those protected assistant-umpire calls.

What TTR can reach in 2026. Only a decision that resulted in a point, and only on a question of fact. That wording is new for 2026 and it matters at the table: it puts the review official inside the rally-by-rally result and outside anything procedural.

Where the operating detail went. The WTT Series & Feeder Handbook 2026 (updated 18 December 2025, effective for events from 1 January 2026) cut its TTR section from roughly 1,090 words across four pages to three paragraphs of about 130 words, and delegated the specifics to a separate "TTR Guidelines" document issued to players and participants rather than published. What disappeared from the public handbook is precisely what an umpire needs to brief a player on:

• the list of reviewable incidents — edge ball, service touching the net, toss height, toss angle, toss below or above the playing surface, hidden ball, palm not open, contact above the playing surface, ball striking the body, ball striking parts other than the net assembly;
• the timing rule that a review had to be requested immediately after the umpire announced the decision;
• the allowance of two unsuccessful reviews per match, with one deducted on each failed request;
• the bar on requesting a review of a serve the umpire did not fault.

The handbook also renamed the "TTR Match Official" to simply the "TTR Official". The practical instruction for officials in 2026: do not brief review procedure from memory or from the 2025 handbook. Read the TTR Guidelines the tournament is actually running under, and confirm at the pre-tournament briefing which tables have TTR installed.

Most table tennis has no TTR at all. It appears at a handful of top-tier events and nowhere else. In a league match, a club night or a national ranking tournament there is no review, no appeal on fact, and the umpire's call stands — which is why the rest of this guide matters more than the review system does.

The umpire is the primary official for each table tennis match. They sit at a small table positioned to the side of the playing surface at net level, giving them a clear view of the net, service, and play on both sides.

Core responsibilities:

• Calling the score aloud after every point (server's score first, then receiver's)
• Declaring the start of each rally by calling the score, in the prescribed order and procedure (3.4.1)
• Enforcing service rules (toss height, visibility, correct bounce sequence)
• Calling lets (net serves, interruptions, receiver not ready)
• Deciding edge balls — whether the ball struck the top playing surface or the side of the table
• Managing timeouts, each player/pair is entitled to one timeout of up to 1 minute per match
• Monitoring toweling, players may towel down every 6 points (when the combined score is a multiple of 6) and at the changeover between sets
• Activating the expedite system when applicable
• Issuing warnings and penalties for misconduct (yellow card, yellow + red, red)
• Maintaining tempo, ensuring play resumes promptly between points

Authority: The umpire's decisions on matters of fact are final, with one exception. Where Table Tennis Review (TTR) is installed, a player may appeal a factual decision that resulted in a point, and the TTR official's ruling is final (3.3.3.3). The referee never touches factual calls: the referee decides questions of law — rule interpretation, clothing, equipment and playing conditions (3.3.1.2.10). Note also 3.3.2.7: a call the assistant umpire makes under 3.3.2.5 — illegal service, service touching the net assembly, obstruction, disturbed conditions, timing — cannot be overruled by the umpire, only by a TTR official.

Positioning: The umpire sits with the net directly to their left or right (depending on convention), at the same height as the playing surface. This position gives the best angle for judging net lets, edge balls, and service toss height.

Service legality is the most frequently contested area of table tennis officiating. The umpire must verify all of the following on every serve:

1. Open palm, stationary ball: The ball must rest freely on the server's open, flat palm (fingers extended, not cupped). The ball must be stationary before the toss begins. Spinning the ball on the palm or holding it with the fingers is a fault.

2. Toss height — minimum 16cm: The server must toss the ball near-vertically upward at least 16cm from the resting position on the palm. The umpire judges this by eye, there is no measuring device. In practice, the umpire watches for a visible upward trajectory that clearly separates the ball from the hand.

3. Striking on the descent: The server must contact the ball after it has passed the peak of the toss and is descending. Striking the ball while it is still rising is a fault.

4. Correct bounce sequence: The ball must bounce first on the server's side, then on the receiver's side. If the ball goes directly over the net without bouncing on the server's side, it is a fault.

5. Visibility: Law 2.6.4 frames this from one point of view only: from the moment the ball leaves the palm until it is struck, it must not be hidden from the receiver by the server, the server's doubles partner, or anything either of them wears or carries. The server clears their free arm away from the space between the ball and the net as soon as the ball has been tossed. The officials come in through 2.6.6: the server must serve so that the umpire and assistant umpire can be satisfied the service complies. This is the most commonly penalised service fault.

The warning is for doubt, not for a first offence. This is the most misunderstood rule in table tennis officiating. Law 2.6.6 puts the burden on the server: it is the player's responsibility to serve so that the umpire or assistant umpire can be satisfied the service complies, and either official may decide a service is incorrect. A serve the official can see is illegal is a fault immediately — there is no free first one.

The warning in 2.6.6.1 covers a different situation. If the umpire or assistant umpire is not sure about the legality of a service, they may, on the first occasion in a match, interrupt play and warn the server. After that, "any subsequent service by that player or his or her doubles partner which is not clearly legal shall be considered incorrect". Two consequences officials get wrong: the warning is once per match, not once per game, and in doubles it carries across to the partner — the pair gets one benefit of the doubt between them, not one each. The warning carries no card and costs no point.

One narrow relaxation exists: under 2.6.7 the umpire may relax the service requirements for a player whose physical disability prevents compliance (3.3.2.3.4).

A let is a stoppage where the point is not counted and the rally is replayed. The umpire calls a let in the following situations:

1. Net serve (service let): The serve touches the net assembly (the net, its suspension, or the posts) but otherwise lands legally on the receiver's side. This is the most common let call. There is no limit to consecutive service lets — if the serve hits the net 10 times in a row and lands legally each time, 10 lets are called.

2. Receiver not ready: If the receiver is clearly not in position or not prepared when the server serves, the umpire calls a let. The receiver cannot stand passively and claim they weren't ready after losing the rally — the umpire must judge whether a genuine lack of readiness was apparent before the serve was struck.

3. External disturbance: If play is interrupted by a ball from an adjacent table, a loud noise, a person walking through the playing area, or any other external factor beyond the players' control, the umpire calls a let.

4. Expedite system — umpire error: If the umpire or assistant umpire incorrectly stops play (e.g., miscounting returns under the expedite system), a let is called.

What is NOT a let:

• The ball touching the net during a rally (after the serve) — play continues.
• A ball that hits the net on the serve and goes off the side of the table, this is a fault (point to receiver), not a let.
• The server tossing the ball and catching it without striking, this is allowed if the umpire judges the player was not attempting to serve, but the umpire may warn against repeated deliberate no-serves.

Edge ball calls are among the most difficult and controversial decisions in table tennis. The distinction is simple in theory but extremely challenging in practice at match speed:

Top edge = IN: If the ball strikes the top edge of the playing surface (the flat top of the table), it is a legal ball. The ball changes direction unpredictably — often skidding low or bouncing sideways, making it nearly impossible to return. The point counts.

Side = OUT: If the ball strikes the side of the table (the vertical face below the top edge), it is out. The opponent scores the point.

How the umpire decides: The key visual cue is the ball's trajectory after contact. A ball hitting the top edge typically bounces upward or forward (even if at a sharp angle), while a ball hitting the side typically deflects downward or away without an upward bounce component. The sound can also help — edge balls on the top surface produce a distinctive "click" different from a side hit.

Assistant umpire's role: The assistant umpire sits directly opposite the umpire, on the other side of the table, and regulation 3.3.2.4.1 gives them one specific job: deciding whether the ball touched the edge of the playing surface at the side of the table nearest to them. That is their own decision, not advice to the umpire — and unlike the calls listed in 3.3.2.5, an edge-ball call is not among the decisions the umpire is barred from overruling.

Player disputes: Edge balls are a frequent source of disputes. In recreational play without officials, good sportsmanship dictates that if there is genuine doubt, the point is replayed. In officiated matches, the umpire's call is final.

Table tennis has several time-management rules that the umpire must enforce:

Between points: Play should be continuous throughout a match. Excessive delay between points is not permitted. The umpire may issue a warning for deliberate time-wasting and can award a point to the opponent for persistent delays.

Toweling rule: Players may towel down (wipe sweat with a towel) at specific intervals:

• When the combined score of both players reaches a multiple of 6 (e.g., at 3-3, 5-1, 4-2, 7-5, etc.)
• At the changeover between sets
• At other times only with the umpire's permission (e.g., after a long rally that leaves a player visibly sweating)

The rule text (3.4.4.1.2) reads "after every 6 points from the start of each game and at the change of ends in the last possible game" — so the count restarts each game, and the extra towelling break in the deciding game comes at the 5-point change of ends, not at every change of ends.

The umpire tracks the combined score and announces when toweling is permitted.

Timeouts: Each player (or pair in doubles) is entitled to one time-out of up to 1 minute per match. It can only be requested between rallies, and it is signalled by making a "T" sign with the hands (3.4.4.2.3). On a valid request the umpire suspends play and holds up a white card on the side of the player who asked, placing it on their court; the card comes down and play resumes as soon as that player is ready or after 1 minute, whichever is sooner (3.4.4.2.4–3.4.4.2.5). The white card is a marker, not a sanction. If both sides request a time-out simultaneously, they share the single minute and neither is entitled to another time-out in that match (3.4.4.2.6). In an individual event the request may come from the player or the designated adviser; in a team event from the player or the team captain — and if they disagree, the player decides in an individual event and the captain decides in a team event (3.4.4.2.1–3.4.4.2.2).

Injury suspension: This is a referee decision, not the umpire's. Under 3.4.4.4 the referee may allow a suspension of play "of the shortest practical duration, and in no circumstances more than 10 minutes", if a player is temporarily incapacitated by an accident, and only if the suspension is not unduly disadvantageous to the opponent. The threshold is deliberately high: 3.4.4.5 excludes any disability that was present or reasonably to be expected at the start of the match, and names cramp and exhaustion as explicitly not qualifying, because they come from the player's fitness or from how the match has gone. Bleeding is a separate, mandatory stoppage — play is suspended immediately and does not resume until the person has been treated and all traces of blood are gone from the playing area (3.4.4.6).

Where players may go: Players stay in or near the playing area throughout the match unless the referee permits otherwise, and during intervals between games and time-outs they must remain within 3 metres of the playing area, under the umpire's supervision (3.4.4.7).

Changeover between sets: Players have up to 1 minute between sets. They may remain at the table or leave the playing area briefly. In the deciding game players change ends as soon as either side reaches 5 points, and that change of ends carries its own brief towelling interval under 3.4.4.1.2 — a short break, not a further full minute.

The expedite system is activated when a game has lasted 10 minutes and fewer than 18 points have been scored (combined). It can also be introduced earlier at any time, but only if both players or pairs request it (2.15.1). The umpire runs this with support from the assistant umpire:

Activation procedure:

1. The umpire stops play. If a rally is in progress when the 10 minutes expire, that rally is interrupted and does not count; play resumes with a service by the player who served in the interrupted rally. If the ball was not in play, the player who received in the immediately preceding rally serves next (2.15.3).
2. The umpire announces: "Expedite" and the system takes effect from the next point.
3. Play continues under expedite rules for the remainder of the match.

Counting returns: Under the expedite system, the assistant umpire (or a designated counter) counts the receiver's returns aloud: "1, 2, 3... up to 13." If the receiver successfully returns the ball 13 times, the receiver is awarded the point automatically. The server's initial stroke is not counted.

Service rotation: Service alternates every single point under the expedite system (same as deuce rules).

Umpire judgment: The umpire must be prepared to explain the expedite system to players who may be unfamiliar with it, particularly at amateur or lower-level events where it is rarely seen. Warning both players at around 9 minutes is common officiating practice rather than a rule — the Laws set no advance-notice requirement.

In practice: The expedite system is extremely rare in today's table tennis with 11-point sets. It was more common under the old 21-point system, particularly in matches between defensive players.

Umpiring doubles table tennis requires tracking the strict hitting and serving rotation:

Hitting order: Players must alternate hits in the sequence: A serves → X receives → B returns → Y returns → A returns → X returns → and so on. If a player hits the ball out of sequence, the umpire immediately awards the point to the opposing pair.

Service rotation within a set: The umpire must track the 4-player serving and receiving rotation:

1. Player A serves to Player X (2 points)
2. Player X serves to Player B (2 points)
3. Player B serves to Player Y (2 points)
4. Player Y serves to Player A (2 points)
5. Cycle repeats

Between games: At the start of each new game the pair that received in the previous game now serves, and it chooses which of its players serves first. The receiving pair has no such choice after the first game of the match: under 2.13.4 the first receiver is automatically the player who served to that new first server in the preceding game. Umpires who let the receiving pair pick lose the rotation immediately.

In the deciding set (changeover at 5): When a pair reaches 5 points in the deciding set, pairs switch ends AND the receiving pair must switch their receiver. The player who was not receiving at the time of the changeover becomes the new receiver.

Common errors the umpire catches:

• Wrong player serving (out of rotation)
• Wrong player receiving
• Same player hitting twice consecutively
• Serving to the wrong diagonal half

The umpire should keep a written rotation chart to track the correct order throughout the match.

The umpire manages player behaviour through a graded ladder in regulation 3.5.2. The ladder is precise, and it is routinely described wrongly — including the widespread claim that a red card alone means two penalty points. It does not.

Yellow card — warning (no points). For a less serious first offence, the umpire may hold up a yellow card and warn the offender that any further offence is liable to incur penalties (3.5.2.2). Regulation 3.5.2.1 names the conduct: behaviour that may unfairly affect an opponent, offend spectators or bring the sport into disrepute — abusive language, deliberately breaking the ball or hitting it out of the playing area, kicking the table or surrounds, and disrespect of match officials. A yellow marker is also placed on or near the score indicator (3.4.1.5), so the sanction stays visible for the rest of the match.

Yellow and red together — 1 penalty point. If a player who has been warned commits a second offence in the same individual match or team match, the umpire awards 1 point to the opponent, holding up a yellow and a red card together (3.5.2.3).

Yellow and red together again — 2 penalty points. For a further offence the umpire awards 2 points, again showing both cards together (3.5.2.3). Note that the escalation is 0 → 1 → 2, so a player who reaches this stage has conceded 3 penalty points in total.

Then it leaves the umpire. Once 3 penalty points have been awarded in the same individual or team match and the player continues to misbehave, the umpire suspends play and reports immediately to the referee (3.5.2.4). A serious offence bypasses the whole ladder: the umpire suspends play and reports to the referee at once (3.5.2.2). Changing a racket mid-match when it has not been damaged is also a matter for the referee: the umpire suspends play and reports (3.5.2.5).

The red card on its own is not a penalty-point sanction. The umpire shows a red card alone only to send an adviser away from the playing area (3.5.1.2, 3.5.1.4, 3.5.2.7). The referee shows a red card when disqualifying a player from a match, an event or a competition for seriously unfair or offensive behaviour, whether the umpire reported it or not (3.5.2.8). A player disqualified from two matches of an event is automatically out of that event (3.5.2.9); anyone sent away from the playing area twice in a competition may be disqualified for the remainder of it (3.5.2.10). Disqualification forfeits any associated title, medal, prize money and ranking points (3.5.2.11). For less serious offences that do not justify disqualification, the referee may report the matter to the ITTF Integrity Unit (3.5.2.8).

Doubles: a warning or penalty incurred by either player applies to the pair; at the start of a doubles match the pair is treated as carrying the higher of any warnings or penalties either player picked up earlier in the same team match (3.5.2.6).

Advice (coaching) — the modern rule. The old restriction of coaching to intervals is gone, and guides that still repeat it are out of date. Under 3.5.1.3 players may receive advice at any time except during rallies, provided play is not thereby delayed. In a team event, advice may come from anyone authorised to be at the playing area (3.5.1.1). In an individual event it may come only from one person designated to the umpire beforehand (3.5.1.2).

Illegal advice is policed with cards shown to the adviser, not the player. An unauthorised person giving advice is sent away on a red card immediately (3.5.1.2). An authorised adviser who advises illegally — during a rally, or in a way that delays play — is first warned with a yellow card (3.5.1.3); if anyone then advises illegally again in the same match, the umpire shows a red card and dismisses them, whether or not that person was the one warned (3.5.1.4). A dismissed adviser cannot return for the rest of the team match — except when required to play — and cannot be replaced (3.5.1.5); if they refuse to leave or come back early, the umpire suspends play and reports to the referee (3.5.1.6). None of this prevents a legitimate appeal or a consultation with an interpreter (3.5.1.7).

Practical tips for umpires:

• Stay calm and composed when issuing cards
• Show the card clearly to the player, the referee (if present) and the scorer
• Record the offence on the match report
• Do not argue with players about factual calls — the decision stands
