I have a PDF(28x17") which I print using the landscape mode in a legal(8.5x14") paper. But this effectively reduces the font size by 50%. What size should I choose for the PDF if I would like the font size to be atleast 75%?. I have the following constraints on width/height of the PDF.
1)Width may be increased further(28+) but not decreased below 28
2)Height may be decreased/increased.(decreased not less than 9")
Is there any way to increase the font size in the paper?
