Chess is a popular game that has been around for centuries, and it is played in tournaments all over the world. It is important to know the size of the chess board used in tournaments, as this can affect the game. The World Chess Federation (FIDE) states that the size of the square for competitive play should be between 5 and 6 cm (1.97 inches to 2.36 inches), with a recommended height for the king of 9.5 cm (3.74 in). This is the official game and board of the FIDE World Championship used in the last matches of the FIDE World Championship.
When it comes to tournament play, there are certain rules and regulations that must be followed. The standard chessboard size for tournament play is 2 inches square, with a king size of 3.75 inches. Most players use plastic chess pieces and roll-up vinyl chess boards or mouse pads for tournament play, as these are quite affordable and meet the regulations set by the United States Chess Federation (USCF). The size of a chessboard can range from 16 to 20 inches (40.6 to 50.8 centimeters).
It is generally accepted that the best-sized chessboard has a square size of 2 inches and measures about 17 to 21 inches wide, allowing good space for the piece to fit on the board and move freely during the game. The official recommendation of FIDE for the standard size of a chessboard is that each of the 64 squares on a board should measure between 2 and 2.5 inches. The Staunton pieces, which are easily the most recognizable of all chessboards, are named after the 19th century English master, Howard Staunton, considered the strongest player in the world in the 1840s. These are the exact same chess pieces that USCF uses in all its national chess tournaments.
In addition to large chess pieces, almost the size of a tournament, travel sets can have almost tiny proportions, and a popular variety of magnetic games is a small wallet-type board with flat disc-shaped pieces adorned with diagram symbols (in fact, this author learned to play in one of those sets). Rolling boards can be difficult to flatten and remove wrinkles, but they are more resistant to wear and tear, while many bars have half a folding board in the back of their supply cabinet, as time and wear and tear can cause the two halves to separate. The dimensions of a tournament chessboard should remain an important factor when selecting one for your own use, whether you need it to be portable, you plan on using it at club events or you are simply looking for an ornamental piece for your home. To summarize, tournament players must use a chessboard with 2 ¼ inch squares and a king size between 3 ¾ and 4 ¼ inches. The standard size for tournament play is 2 inches square with a king size of 3.75 inches.
The official recommendation from FIDE is that each square on a board should measure between 2 and 2.5 inches.
