A standard chess board has 64 individual squares, but 204 squares if you count squares of all sizes. A regulation board consists of eight squares in each direction.
To determine the amount of squares on a chess board, count the number of squares of each size. There is one eight-by-eight square, but four seven-by-seven squares. Continuing down by size, there is nine six-by-six squares, 16 five-by-five squares, 25 four-by-four squares, 36 three-by-three squares, 49 two-by-two squares and 64 single squares. Adding these all together yields 204 total squares on a chess board.
