Sizing Chess Pieces to Chess Boards
There are a number of formulae which can be used to determine whether a chess set "fits"
a chess board or not. These formulae look at the ratio between the King's base diameter and the size of the square on the
chess board. The common method is to use a ratio of between 0.68 and 0.75 between the Kings base diameter (KBD) and the length of
the side of the chess board square. Since good quality chess boards usually fall into three sizes, i.e. 50.0 mm, 55.0 mm and 60.0
mm squares, probably the easiest way to match them up is to consider the following:
For a 50.0 mm chessboard the king's
base diameter should range between 34.0 mm and 37.5 mm.
For a 55.0 mm chessboard the king's base diameter should
range between 37.5 mm and 41.25 mm.
For a 60.0 mm chessboard the king's base diameter should range between 41.00
mm and 45.0 mm.
Therefore, if the base diameter of the king in your favourite chess set is, say, 40.0 mm then to avoid crowding
the board, you will require a chessboard with 55.0 mm squares. (KBD = 40.0, Side of square = 55.0) Therefore ratio is : 40.0/55.0 =
0.72, which falls neatly between 0.68 and 0.75.
Castle Chess Board Sizes are the following:
A chessboard with 51.00 mm Squares :
The Playing Surface is 408
mm long x 408 mm wide and is raised 15.0 mm above the frame.
The Frame Size is 464 mm long x 464
mm wide x 37.5 mm high.
The Overall Size is 464 mm long x 464 mm wide x 52.5
mm high.
A chessboard with 55.00 mm Squares :
The Playing Surface is 440 long x 440
mm wide and is raised15.0 mm above the frame.
The Frame Size is 496 mm long x 496 mm wide x 37.5
mm high.
The Overall Size is 496 mm long x 496 mm wide x 52.5 mm high.
