If the chess board is too small, then the pieces will not be able to fit on the board and will provide a clumsy experience as each piece will have to be lifted high enough to clear other when making longer moves with pieces like, the Queen, Rooks or Bishops.

You can find out what size chessboard you need by measuring your chess pieces and by measuring the squares on the chessboard.

The other thing to consider when deciding what size chess board to buy is where you will be keeping it. Where will the board be stored when not in use?

Of all considerations when choosing a chess board size, one that can often be overlooked is quality.

A high-quality chessboard will be made of durable materials, have a smooth surface, and have craftsmanship that will withstand years of use.

The size of a chessboard is not going to be representative of the quality and we should consider that a larger board doesn’t always mean better quality.

By the same token, a smaller board may be easier to handle and cheaper to make, but again, the quality should always be considered if you want one will stand the test of time, and a lot of gameplay.
