Consider the lefthand vertical edge of a square of size 1 x 1.
This edge can be in any one of 8 positions. Similarly, the top
edge can occupy any one of 8 positions for a 1 x 1 square.
So the total number of 1 x 1 squares = 8 x 8 = 64.
For a 2 x 2 square the lefthand edge can occupy 7 positions and
the top edge 7 positions, giving 7 x 7 = 49 squares of size 2 x 2.
Continuing in this way we get squares of size 3 x 3, 4 x 4 and so on.
We can summarize the results as follows:
Size Of square Number of squares
--------------- -----------------
1 x 1 8^2 = 64
2 x 2 7^2 = 49
3 x 3 6^2 = 36
4 x 4 5^2 = 25
5 x 5 4^2 = 16
6 x 6 3^2 = 9
7 x 7 2^2 = 4
8 x 8 1^2 = 1
---------------
Total = 204
There is a formula for the sum of squares of the integers
1^2 + 2^2 + 3^2 + ... + n^2
n(n+1)(2n+1)
Sum = ------------
6
In our case, with n = 8, this formula gives 8 x 9 x 17/6 = 204.

It depends on what type of chess you are talking about, There are western chess, The western version of chess is a game played on an board, called a chessboard, of alternating black and white squares. It is an 8×8 board and the 64 squares are of alternating color; usually, but not necessarily, black and white.
The 3 x 3 = 9 square board is used in tic-tac-toe. The 8 x 8 = 64 square board is used in checkers and chess. Go is played on a board in which pieces are placed on the intersections (as opposed to the squares bounded by the grid lines) of a set of 19 x 19 = 361 equally spaced lines on a square grid.

204 SQUARES in ALL.
Here are the details:
There are many more different-sized squares on the chessboard.
The complete list of answers is shown below:
"1, 8x8 square
4, 7x7 squares
9, 6x6 squares
16, 5x5 squares
25, 4x4 squares
36, 3x3 squares
49, 2x2 squares
64, 1x1 squares
Therefore, there are actually 64 + 49 + 36 + 25 + 16 + 9 + 4 + 1 squares on a chessboard! (in total 204).

1x1 squares: 64
2x2: 49 (7 rows with 2 squares by 7 columns with 2 squares)
3x3: 36 (same reason as above, use 6 instead of 7)
4x4: 25
5x5: 16
6x6: 9
7x7: 4
8x8: 1
Total number: 64+ 49 + 36 + 25 + 16 + 9 + 4 + 1 = 204

I would almost reflexively say, "64," but I wonder whether this is not a trick question. If you count the entire chessboard itself, then the answer is 65. However, one could easily observe numerous other "squares" in an ordinary chessboard. I can't tell you now what the "real" number is, but in such case it would be far greater than 64.

Sorry, but there aren't any more than 64. The back row is 2 castles, 2 bishops. 2knights, a king and a queen. Eight squares. The board is exactly the same lengthwise as it is widthwise, or eight rows. Eight times eight is 64, and that's how many squares there are on a chessboard.

Tricky tricky. If the little "man-sized" squares are 1", then there are 64 1x1 squares, but there are also the 2x2, the 3x3, etc. And don't forget the whole board is... TA DA!!!!!!
a SQUARE!!!! I'm not gonna count them all, but I like this question....makes ya think.
