Control Font Sizes and Column Widths in PDF Reports

When I create a report and save it as a PDF, in some cases the font size that is selected is just too small to be readable. This is particularly a problem if a column such as "Feature Description" is included in the report. It would also be great to be able to control the width of each column; by default the feature description column takes up 75% of the available page width. This is a free-text field, there is no reason it could take up less horizontal and more vertical space.
