"For those that have not heard, the DGT board allows you to play chess against your computer on a real, wooden board. The board is a nice size with squares that are about 2" on a side. The wood used in the board looks like maple and walnut. The piece sizes are well matched to the board (the King is about 3.75" tall)."

What is the most common sized DGT board/pieces that you see often in tournaments? For example here
From what I can tell this is a "German Knight" DGT set. But what size is the board and king?
