Use the density table to choose pixels for standard lab prints, enlargements, or high-resolution masters.

Most phone and camera images are not exactly 2:3, so inspect the crop before ordering prints.

Use cases and print tips

  • Order standard lab photo prints, postcards, or small framed images.
  • Use a 2:3 crop for a borderless 4 × 6 print.
  • Keep faces and text away from the edges when a phone image needs cropping.
