The World Chess Federation (FIDE) recommends that the squares on the chessboard measure between two and two and a half inches. The entire chessboard it contains will fall in the range of sixteen to twenty-one inches. The typical size of a regulatory chessboard is twenty-one inches long and twenty-one inches wide. There is an official tournament guide for placing chess pieces on a chessboard and vice versa.
It states that the diameter of the king's base must not exceed 75% of the diameter of the squares on the chessboard. For example, a king with a base diameter of 1.5 inches must have a square diameter of 2 inches. To ensure sufficient stability, the diameter of the base of each piece must be between 40 and 50% of its height. Therefore, a King who is 3.75 inches tall or 9.53 cm tall should have a base diameter of between 1.5 inches or 3.81 cm and 1.88 inches or 4.76 cm.
Whether you're an active player, an avid enthusiast, or a serious collector, follow these basic guidelines when buying your next chess set and it's unlikely that you'll get mistakes, whether functional or aesthetic. There are travel chess sets or novel miniature chess sets in which the pieces can measure only 1.5 inches or 3.81 cm or even smaller. The pieces must match a chessboard correctly and with an almost unlimited number of combinations of tables and pieces, knowing the size of the tournament will help you select the combination of board and set that best suits you. Sometimes it is advantageous to have 26% checkerboard pieces show a characteristically high color contrast between the pieces and the playing squares.
So what is the best-sized chessboard? The best-sized chessboard measures 21 inches long by 21 inches wide by 0.75 inches thick. For example, the United States Chess Federation, the governing body for chess in the United States, has specific equipment standards described in its rules. But most experts agree that if you must deviate from the norm, opt for a board that is slightly larger in relation to the pieces, and not the other way around. Below is the official FIDE World Championship chess set used in the last matches of the world championship.
The pieces weigh heavily for a great chess playing experience and are beautifully finished with a luxurious felt billiard base. If you are thinking of buying both chess and chessboard pieces, first choose the board that fits your home and then choose the appropriate pieces for that chessboard, in that order. Match the pieces and the chessboard aesthetically or make the pieces and the board have a high relative contrast to facilitate the game. Some of these games have magnetic pieces that are attached to specially manufactured chess boards that contain iron sheets under the playing surface, to compensate for the lack of weight and stability that these much smaller pieces possess.
The sizes, rules, specifications, proportions and tricks for setting up a tournament chessboard can be overwhelming, but if you focus on practicality, it will be relatively easy for you to measure chess on board and establish combinations that are suitable for tournament levels of overplay.
