Scan-to-Print Conversion Chart

The table below considers what scanner DPI would be most appropriate for the more common scanned picture sizes if reprinted into one of the 8 standard photographic print dimensions. The table includes a recommendation for both ‘good’ print and ‘high’ print quality. For the purposes of this chart, good print quality. is the ability to print at a resolution between 600-720 dpi (scan @ 200+) and high print quality between 1200-2800+ dpi (scan @ 300+).

The scanner’s resolution displayed in this chart is determined, based upon achieving an adequate sampling of pixels during digitization, to obtain the printing standard described above. A minimum of  300 dpi was used for scanning of all photos.

Scan Tips

1. Always scan at no more than your maximum optical resolution.
2. Use the lowest compression rates.
3. Scanning photos @ 600 dpi optical resolution will achieve over 75% of output of all sizes @ high print quality & 80% @ good print quality..
