Chess Board Size Guide
When determining the size of chess board square that will work best for your chess pieces, consider both the height of the chess pieces and the base diameter of the largest piece, typically the king, when deciding on the appropriate size of the chess board squares. Taller pieces with a narrow base will require square sizes based on their height to allow adequate space for movement during the game. Conversely, shorter pieces with a wider base will necessitate square sizes based more on their base diameter than their height. Ultimately, the ideal square size depends on personal preference, with some players preferring a tightly spaced board for aesthetics, while others favor wider spacing for a better view.
