Is 300 DPI the right choice for a 4 x 6?

At 300 DPI a 4 x 6 scans quickly and reproduces at its own size perfectly, which is fine for sharing and everyday reprints. What it cannot do is grow: enlargements and serious restoration both want more pixels than this setting captures. If the photograph is irreplaceable, step up to 600 DPI.

Different print or setting? The interactive calculator covers every combination, and the DPI advisor picks the setting for you. The technique itself, glass cleaning and all, is in the scanning guide.

Common questions

How many pixels is a 4 x 6 photo at 300 DPI?
1200 x 1800 pixels, which is 2.2 megapixels. The arithmetic is simply inches multiplied by DPI on each side.
Is 300 DPI enough for a 4 x 6 print?
It depends what the scan is for. 300 DPI reproduces the print at its own size perfectly, but leaves no headroom to enlarge. If the photo matters, 600 DPI costs seconds more and future-proofs the file.
How big is the file?
Roughly 0.6 MB as a high-quality JPEG, or about 6.2 MB as an uncompressed TIFF master. Keep the TIFF for photos that matter; export JPEGs for sharing.
