Direct answer. Set the photo to 5 × 7 in (127 × 178 mm) in PrintExactly, place it on a sheet that matches the loaded paper, confirm Scale to Fit is off and Scale is 100%, then print.

The 3-step method

  1. Set the Photo Frame to 5 × 7 in (127 × 178 mm). Open PrintExactly and type 5 in × 7 in, or 127 × 178 mm, as the Frame dimensions. This is a standard small print size and a common greeting-card size.
  2. Place on the right sheet for the job. For one 5 × 7, use Letter or A4. For multiple copies or mixed sizes, set copies per item and use Auto Arrange to pack the sheet.
  3. Verify printable area and 100% scale, then print. Turn off Scale to Fit in the macOS print panel, set Scale to 100%, and confirm the printable area shows the full 5 × 7. Send the job.

Why a 5 × 7 photo prints the wrong size on Mac

  • Scale to Fit silently scales the print. The macOS print panel may default to Scale to Fit if the document page size does not match the loaded paper. Match sizes first.
  • Driver-level scale. Some printer drivers apply their own scale-to-fit on photo paper presets. Open the driver's own preferences and set Fit to Off.
