What is the largest sharp print size from 35mm film?
A 35mm film negative will produce a sharp 12-inch by 18-inch print when scanned at a resolution of 300 dots per inch (dpi) by the photo printing lab equipment. Larger print sizes are possible, but the grain structure of the film emulsion becomes more visible as the print size increases, making the print appear fuzzy.Source:Design 215: Megapixels vs.
