How the result works
Print width equals pixel width divided by DPI, and the same formula applies to height. Higher DPI places more pixels into each inch for a finer print, while lower DPI creates a larger print from the same image. Viewing distance and printer quality also affect the result.
- Use 300 DPI for close-viewed photo prints
- Try 200–240 DPI for larger casual prints
- Restore old scans before enlarging them
Common questions
What DPI should I use for photo printing?
300 DPI is a common target for close-viewed photo prints, while 200–240 DPI can still work well for larger prints.
How do I calculate print size?
Divide pixel width and height by the selected DPI to get inches, then multiply inches by 2.54 for centimeters.
Can enhancement improve a small scan before printing?
It can improve perceived clarity and create a more usable copy, but generated detail is not identical to information captured in the scan.
