How many squares?

An oldie but a goodie from Chuckles. For the purpose of this question, do not count the outer border as two – that extra border was artistic license, not part of the puzzle:

    My attempts:

    1 outer
    18 second smallest
    8 four-squarers
    8 little ones
    4 nine-squarers

    That’s 39 to this point.

    Plus the middle 4 squarer I’d missed earlier.

    40. I was sent the solution but had to find the 40th one.
