How many fit on a sheet

  • A4 (210 × 297 mm)Up to ~2 at true size — Four true-size 10×15 prints do not fit without shrinking.
  • Letter (215.9 × 279.4 mm)Up to ~2 at true size — Similar packing limit to A4.

Important when printing

Select Actual Size / 100% in your printer dialog. Do not select “Fit to Page” or “Scale to Fit” — that changes the physical size.

Print settings checklist

  • Export a PDF from PhotoSheet Pro at the paper size you will load.
  • In the print dialog choose Actual Size or 100% scale.
  • Turn off Fit to Page, Scale to Fit, and “shrink to printable area”.
  • Select the matching paper size in the printer tray settings.
  • If using borderless, expect slight overscan crop — add a small margin if edges matter.
