You could try this:

In between column A and B (column header) you could use pixels as the size
measurement instead of the height or width.

Say 100 pixels each, will give a perfect square.

HTH.

Does anyone have any suggestions on how to fit each cell into perfect square?
I would like to make each cell into a perfect square, but the lenght and
height for each cell used different unit. Does anyone know the proportion for
each cell between length and height? so I can multiple the length with a
ratio to get the other length in order to get a perfect square.
Thanks in advance for any suggestions
