How to specify font size less than 10pt (or more than 12pt)?

Many questions in this matter has been posted and most of the answers are related to either using KOMA-script class or using XeTeX, or using the \documentclass{extreport} which doesn't have a 13pt. So if a report class with default font size of 13pt is required, what should I do?
