The largest chess piece is a king piece which measures 6.09 m (20 ft) tall and 2.79 m (9 ft 2 in) in diameter at its base, and was achieved by World Chess Museum, Inc. DBA World Chess Hall of Fame (USA) in Saint Louis, Missouri, USA, on 6 April 2018.
The World Chess Hall of Fame decided to set a Guinness World Records title for the largest chess piece to kick off the opening of the 2018 Spring exhibitions - featuring an entire gallery that celebrates the 10-year anniversary of the Saint Louis Chess Club, along with a decade of hosting the U.S. and U.S. Women's Chess Championships in Saint Louis.
The chess piece is 53 times the size of a standard "Champion Staunton" king piece. The chess piece is constructed of Sapele African Hardwood and Wood Glue. It was assembled into oversize rough blocks then sculpted using wood working tools.
