I set the Excel page to 8.5 by 11 inches and set the margin to be 0.25 inch on each side, and try to fill the printed page with cells.
When I set column width to be 4 inches. In page layout view mode, 2 columns can't fit into one page. (4+4+0.25+0.25=8.5)
When I set column width to be 8 inches, one column can actually fit into one page.
When I set the row height to be 5.25 inches, 2 columns and margin are supposed to fill the whole page because 5.25+5.25+0.25+0.25=11. However an extra row of about 0.2 inch fits into the page.
I know the problem sounds trivial, but I really just want to figure out what is wrong.
Notes
I'm currently using the 2013 version of the excel.
I don't think the border matters since the result doesn't change when I adjust the border thickness.
The problem exists in a new blank excel with no other presetting such as scaling.
