Recommended maximum print sizes for scanned media
So why should you care about high resolution?
It depends. If you have 4×6 snapshots, then 300 dpi scans are fine for archiving. You can still print a good looking 7×10 enlargement.
For a small wallet-size picture, scan at 600 dpi so you can enlarge it and retain more detail. Got a photo of a group of people? 600 dpi will allow you to zoom in and crop.
Slides and negatives are smaller so they’re scanned at a higher dpi rate. Better to have too much resolution. You can always go down in size; you can’t go up without losing quality.
We copy your prints at 6000 PPI
|Scanned Media||300 DPI – Excellent||200 DPI – Good||150 DPI – Acceptable|
|4×6 photo: 300 dpi||4″x6″||7″x10″||10″x14″|
|4×6 photo: 600 dpi||8″x12″||13″x20″||17″x26″|
|8×10 photo: 600 dpi||16″x20″||24″x36″||32″x40″|
|35mm slide: 2000 dpi||7″x10″||10″x15″||13″x20″|
|35mm slide: 4000 dpi||14″x21″||20″x30″||26″x40″|
A scanned photo has more resolution than you will see on a computer monitor or TV
A pixel is an individual dot on the screen. More dots mean higher resolution. Monitors cannot resolve at the same sharpness as a printed photo. This chart shows that the pixel density increases as the monitor gets smaller. However, you will view the image at a greater distance as the monitor size increases. You’ll view your iPhone (326 ppi) at about 15 inches. You’ll watch that HDTV (48 ppi) on a couch ten feet away.
|Digital Media = PPI||Dimension (pixels)||Resolution|
|40-inch HDTV||1920×1080||48 ppi|
|24-inch monitor||1920×1080||92 ppi|
|21-inch monitor||1920×1080||105 ppi|
|Laptop: 15″ monitor||1920×1080||141 ppi|
|iPhone: 4.7″ screen||1136×640||326 ppi|
