The chart showed that for a font size of 10, the pixel would 13. If I wanted an 8-character date (MM/DD/YY) then the width would be 13 * 8 = 104 which is way too much. 75 as you suggest is a much better fit for Arial 10. So I don't think that chart is a good place to start. What would your utility do -- look at the actual text that's in a column you want to locate?
