Can you count the number of squares in the given picture?

How Many Squares Can You Find

The total number of squares are 17.
Let us assume that the smaller square is 1 unit in size.

Number of squares with 1 unit size = 12
Number of squares with 2 unit size = 5

There is no square with 3 unit size.

Thus total number of squares = 12 + 5 = 17.
