Frequently asked questions

How many pixels is A4 at 300 DPI?

What DPI should I use?

300 DPI for photos and documents viewed up close, 150 DPI for posters seen from a distance, and 72–96 DPI only for screen use.

Are DPI and PPI the same?

For files, people use them interchangeably: both mean pixels per inch of the printed result. Printers also have their own dot resolution, which is a different thing.
