Which DPI should I use?

72–96 DPI is enough for on-screen PDFs and email. Use 150 DPI for good-quality office printing and 300 DPI for professional print and photos. 600 DPI is for line art and archival scans; file sizes grow with the square of the DPI.

PDF pages are measured in points (1 pt = 1/72 inch), so an A4 page is 595 × 842 pt regardless of the images placed on it.
