Scan resolution & print size
How big can you print from a scan? Pick your format and scan DPI.
About this tool
Scanning resolution decides how much detail you capture from a negative and how large you can print. Enter the film format and the scan dpi, and this tool returns the resulting megapixels and the biggest quality print size. Use it to pick a scan setting that matches your intended output without wasting file size.
How to use it
- Select the film format so the scanned area is known.
- Enter the scanning resolution in dpi.
- Read the output megapixels and the maximum recommended print size.
FAQ
Does a higher dpi always give a better scan?
Only up to the point where the scanner and film grain resolve real detail. Beyond that you enlarge grain and file size without adding sharpness, so match the dpi to your print needs.
What dpi is enough for a good print?
Prints usually look sharp at around 300 dpi at final size. Work backwards from your target print dimensions to find the scan resolution that yields enough megapixels.
