Photo size and pixel problem

This is the quality requirement of digital pictures for printing paper photos of about 8 inches.

Generally speaking, the long side of a photographic work is necessary. The pixel value is too low to print a paper photo of the specified size. 300dpi refers to the resolution setting of the picture, that is, the pixel value that can be provided per inch. In a certain range, the higher the resolution, the better the quality of the printed photos. 300dpi is the maximum resolution for printing beautiful photos.
