FIDE Regulations and the Staunton Requirement
The World Chess Federation — FIDE, from the French Fédération Internationale des Échecs — governs all official chess competition worldwide. Its Laws of Chess specify that pieces used in rated play must follow the Staunton pattern. This is not a recommendation; it is a mandatory requirement. Any event awarding FIDE rating points, from club rapidplay to World Championship matches, must use Staunton-design pieces.
The regulation exists for a straightforward reason: consistent, unambiguous piece recognition. In a tense time-pressure position, a player must identify every piece on the board instantly. The Staunton design gives each piece a distinct silhouette — the cross-topped king, the coroneted queen, the mitred bishop, the horse-head knight, the castle-tower rook, and the ball-topped pawn — with no room for confusion. Alternative artistic designs, however beautiful, introduce visual ambiguity that has no place in competitive play.
The Origins of the Tournament Standard — Jaques of London, 1849
The story of the tournament chess set begins with a single commercial partnership. In 1849, Jaques of London produced a new chess set created by Jaques of London and endorsed by the leading English player of the day, Howard Staunton. The pieces were immediately recognised as superior to anything then available: each figure was visually distinct, mechanically stable, and pleasant to handle. Staunton's endorsement appeared on the original Jaques box, lending the set his name for posterity.
Within a decade, the Staunton pattern had displaced virtually every competing design in British chess clubs. International adoption followed. By the time FIDE formalised the requirement, the Staunton pattern had already been the de facto world standard for nearly a century. Jaques of London remains the original manufacturer, and the Staunton chess set they produce today descends directly from the 1849 original.
Piece Specifications: King Height and Base Diameter
FIDE Article 2.4 sets precise dimensional tolerances for tournament pieces. The king height must fall between 85 mm and 105 mm (3.35 to 4.13 inches). The king base diameter must be 40 to 50 percent of the king height — so a 95 mm king should have a base between 38 mm and 47.5 mm. This ratio ensures the king is stable without occupying an excessive footprint on the board.
The remaining pieces scale proportionally: the queen typically reaches 85 to 90 percent of the king height, bishops and rooks around 70 to 80 percent, knights somewhat lower, and pawns roughly 50 percent of the king height. These ratios are conventions rather than hard specifications, but any set deviating significantly from them will look and feel wrong on a tournament board and is unlikely to receive arbiter approval.
Most recognised tournament sets use a king in the 95 to 100 mm range — large enough to be clearly visible across the board, light enough to handle quickly in blitz and rapid formats.
Board Specifications: Square Size and Contrast
FIDE specifies that board squares must measure between 50 mm and 65 mm per side. The board must have clearly contrasting light and dark squares. There are no restrictions on exact colours — traditional combinations include cream and brown, ivory and ebony, and maple and walnut — provided the contrast is unambiguous under tournament lighting.
The relationship between piece size and square size matters. A rough guide is that the king base diameter should occupy approximately 75 to 80 percent of the square width. A 57 mm square pairs well with a king base of around 42 to 45 mm. Too small a king on a large board looks lost; too large a king on a small board creates a cluttered position and pieces may nudge each other when placed.
Approved Materials
Traditionally, tournament chess sets were made from wood. Fine hardwoods — boxwood and ebonised boxwood, rosewood, sheesham, and maple — produce sets with satisfying weight, warmth to the touch, and longevity measured in decades rather than years. Weighted wooden sets, where a metal disc or screwed-in bolt is added to each piece base, reduce tipping and improve the feel of each move.
FIDE does not restrict materials beyond the Staunton pattern requirement. Plastic sets are fully legal and widely used. At club and school level, a high-quality weighted plastic set offers near-indestructible durability at a fraction of the cost of wood. The pieces resist splitting, warping, and fading — practical advantages in environments where sets are handled daily by many different players.
DGT Electronic Boards — The Technology Behind Live Broadcast
Since the mid-1990s, top-level tournament chess has been transformed by the electronic chessboard. DGT (Digital Game Technology) boards are the industry standard at elite events. Each square in a DGT board contains sensors that detect the presence and type of chess piece above it, using RFID chips embedded in specially manufactured pieces. Every move is transmitted in real time to broadcast software, which feeds live game feeds on chess websites and apps worldwide.
DGT boards look and feel like conventional wooden boards — many are made from genuine wood veneers — but the pieces used with them must be the manufacturer-supplied chipped sets, typically robust plastic Staunton pieces in standard tournament proportions. The Candidates Tournament, Grand Prix events, and World Championship matches all use DGT setups. The Magnus Carlsen vs. Ian Nepomniachtchi 2021 World Championship match in Dubai, for example, used DGT boards with live broadcast reaching millions of viewers.
For club and federation organisers, DGT boards without the broadcast infrastructure are used purely for electronic game recording, automating the task of writing down every move and producing a PGN file at the end of the game. This is increasingly common in national-level events where adjournment analysis has been replaced by digital game records.
The Plastic Tournament Set — Clubs and Schools
For the vast majority of competitive chess — club nights, congress weekends, school championships, inter-county matches — the standard equipment is a weighted plastic Staunton set on a vinyl roll-up board. This combination is practical: lightweight, cheap to replace if lost or damaged, easy to transport, and fully compliant with FIDE regulations.
The Jaques Staunton Triple Weighted set is a popular choice in this category. The pieces reproduce the proportions and silhouette of the original 1849 Jaques Staunton design in durable plastic, with triple weighting in the base for the feel and stability of a wooden set. Paired with a 55 mm square tournament board, these sets are used in hundreds of British chess clubs and satisfy the requirements of the English Chess Federation and FIDE alike.
World Championship Sets — Notable Examples
The chess sets used in famous World Championship matches have become objects of historical interest in their own right. The 1972 Fischer vs. Spassky match in Reykjavik was played on a custom board with oversized pieces, the subject of dispute between the players before play began. The 1997 Deep Blue vs. Kasparov rematch used standard tournament pieces adapted for the computer's robotic arm to move. More recently, the 2023 World Championship between Ding Liren and Nepomniachtchi used DGT Noble pieces — a modern wooden Staunton design — on custom-made boards built for the Astana event.
Jaques of London tournament-grade sets have appeared in British championship matches throughout the twentieth century, and the company continues to supply sets to leading federations and events.
Where to Buy a Tournament-Compliant Chess Set
A set meets tournament requirements if it uses Staunton-pattern pieces with a king height between 85 and 105 mm, on a board with squares between 50 and 65 mm. For club and casual tournament use, a quality weighted plastic set with a roll-up board covers everything needed. For graded wooden sets, boxwood and sheesham Staunton sets from Jaques offer the original design in materials built to last a lifetime. Always check that the king height and base diameter fall within FIDE tolerances before purchasing for competition use.
Jaques of London — Making Chess Sets Since 1849
The Staunton pattern that FIDE mandates for all official chess today was created by Jaques of London. Since 1849, Jaques has produced the definitive Staunton chess set in woods ranging from boxwood and ebony to rosewood and sheesham, as well as weighted plastic sets used in clubs and schools across the UK. Every set is made to the proportions of the original Cook-Staunton design that became the world standard — so when you buy from Jaques, you are buying the original, not an imitation of it.

Q: What chess set is used in FIDE tournaments?
FIDE-rated tournaments must use Staunton-pattern chess pieces. In top-level competitions such as World Championships, Candidates Tournaments, and Grand Prix events, DGT electronic boards with plastic Staunton pieces are standard, enabling live move broadcast to millions of viewers online. Below elite level, wooden Staunton sets are the traditional and widely preferred choice. The Jaques of London Staunton pattern — the original 1849 design — remains the definitive reference against which all other sets are judged, and Jaques sets are used in British and international events at every level.
Q: What size are tournament chess pieces?
FIDE regulations specify that the king height must be between 85 mm and 105 mm (approximately 3.35 to 4.13 inches). The king base diameter must be 40 to 50 percent of the king height — ensuring stable, proportionate pieces that do not tip easily. Remaining pieces scale proportionally: the queen sits at around 85 to 90 percent of king height, bishops and rooks at 70 to 80 percent, and pawns at roughly 50 percent. Most competition-grade sets use a king in the 95 to 100 mm range, balancing visibility with handling speed in blitz and rapid play.
Q: Does FIDE require Staunton chess pieces?
Yes, without exception. FIDE Laws of Chess specify that pieces used in rated play must follow the Staunton pattern. This requirement reflects the near-universal adoption of the Jaques of London Staunton design from 1849, which became the global standard because its clearly differentiated piece silhouettes eliminated confusion during competitive play. No other piece design — however elegant or historically interesting — is approved for FIDE-rated games. Artistic and novelty sets are perfectly fine for casual play at home but cannot be used in any rated match.
Q: What is a DGT chess board?
A DGT board is an electronic chessboard produced by Digital Game Technology (DGT), a Dutch company founded in the 1980s. Each square contains RFID sensors that detect the presence and identity of specially chipped chess pieces, transmitting every move in real time to broadcast software. DGT boards are used in virtually all top-level FIDE events, including World Championships and Candidates Tournaments, enabling live game broadcasts on platforms such as Chess.com and Lichess. The pieces supplied with DGT boards are plastic Staunton sets manufactured to FIDE dimensional specifications, and the boards themselves are typically finished in real wood veneer to preserve the visual character of a traditional chess table.
