Report the inputs, not the image
A useful calculation report includes the page used, pixel width and height, physical width and height, unit, PPI, orientation, bleed and the result you expected.
You never need to send the private image itself to explain a dimension calculation.
Before reporting a discrepancy
Check that width and height were not reversed, confirm portrait or landscape, and distinguish trim size from the full bleed canvas. Include the printer's written requirement when it conflicts with a general default.
