I am trying to convert a Excel document to PDF. The Excel document has 64 pixels width for first 10 columns. I am using the A4 Sheet size for PDF in which the first 10 columns should fit. But, Excel only fits 9 columns. In this document right and left margin set to 0.7 inches. It uses the Arial font and size 10.
Expected :
Portrait Orientation
System Resolution : 1360 x 768
Available Sheet Size after subtracting margin = (8.27 - 1.4) x 96 = 659.52 pixels
First 10 columns with 64 pixels width = 64 x 10 = 640 pixels
640 pixels can be fit into 659.52 pixels PDF page.
Result
Only columns from 1 to 9 is fit into the first page of PDF.
What is logic or behavior of Excel for converting the document to PDF. What kind of scaling it uses?
