Regal Heights

The regal stature of the king takes on fresh significance. A king’s height of 4.75 inches to 5.5 inches is celebrated, granting it the prominence it deserves on the grander board. 

Piece Diameters

Ideally, the king’s base should occupy only 75 to 80% of a square. While overly small pieces can appear lost on the board due to excessive gaps, having more space is preferable. Boards with generous spacing facilitate smooth movement and positioning of pieces.

 An effective way to assess the square-to-piece size ratio is by testing if four pawns can comfortably fit at the inner corners of a single square. This evaluation offers a practical gauge since pawns are significantly smaller than kings. For those favouring smaller squares, two diagonally placed pawns should neatly occupy one square, maintaining harmony on the board.
