Making Squares

One of the (many) frustrating things about Excel is that it uses different units of measurement to specify the height of rows and the width of columns.

Row height is pretty straightforward—it is measured in points. Column width, however, is measured in character widths. If your Standard style is set to Courier 10, then a column width of 12 means that you can fit exactly twelve characters in a given column. For proportional fonts, the character 0 is used to count the characters. (Yup, it's absurd.)

This leads to problems if you want the height and width of a particular cell to match, thereby making a square. Fortunately, with a little macro wizardry you can bypass this oddity of Excel and achieve the desired results. Consider the MakeSquare macro:

```Sub MakeSquare()
Dim WPChar As Double
Dim DInch As Double
Dim Temp As String

Temp = InputBox("Height and width in inches?")
DInch = Val(Temp)
If DInch > 0 And DInch < 2.5 Then
For Each c In ActiveWindow.RangeSelection.Columns
WPChar = c.Width / c.ColumnWidth
c.ColumnWidth = ((DInch * 72) / WPChar)
Next c
For Each r In ActiveWindow.RangeSelection.Rows
r.RowHeight = (DInch * 72)
Next r
End If
End Sub
```

This macro prompts you for the dimension of the square you want to create, and then calculates exactly how wide and high to set each cell. You can run the macro with a single cell selected, or you can make a larger selection set.

The "math magic" is done in the calculating of the WPChar variable. This is set to a value derived by dividing the width of the column in points (returned by the Width property) by the width of the column in characters (returned by the ColumnWidth property). This value, which is the number of points in a character at the current settings, is then used to calculate how many characters should be used to set the width in the next program line.
