How to Create a PDF With Photos at Exact Print Sizes on iPhone
How to create a PDF on iPhone where photos are laid out at exact physical print sizes for later printing or a print shop.
Not everyone wants to print immediately from the iPhone. You may want a PDF to save, email, move to another device, send to a local print shop, print later at home, or archive the exact layout. The useful outcome is a document whose page size and photo frames match the physical sizes you intended — so later printing can reproduce that geometry.
Page size and photo size both matter
An exact-size photo PDF needs two correct ingredients:
- Page size — commonly A4 or US Letter (PrintFit also supports other paper sizes)
- Photo physical dimensions — each photo's width and height on that page in inches, cm or mm
If either is wrong, the print shop or home printer cannot infer what you meant from pixels alone.
What “exact-size PDF” means here
It means the PDF preserves the page geometry of the layout: photos sit in frames at the requested physical sizes on a known paper size. It does not mean every third-party PDF viewer or printer will automatically honour those dimensions. Many apps default to Fit to Page when printing a PDF.
How PrintFit PDF export works
In PrintFit, you choose photos, set sizes (including mixed sizes and multiple copies when they fit), preview the sheet, then generate a PDF locally on the device. You can share it through the iOS share sheet to Files, Mail, Messages or another app. Photos and PDFs are processed locally — PrintFit does not upload them to Confianza servers.
For packing behaviour when several photos share a page, see multiple photos on one page.
Printing the PDF later
- Open the PDF on the device or computer you will print from.
- Choose the same paper size the PDF was built for (A4 or Letter, etc.).
- Select Actual Size / 100% — avoid Fit to Page / Scale to Fit.
- Print a single test page.
- Measure with a ruler before a full run.

When PDF is better than direct AirPrint
- You need to print at a shop that prefers a file
- Someone else will print for you
- You want an archive of the exact sheet layout
- You will print from a Mac or another device
AirPrint remains convenient when you are at a compatible printer and ready to print now. Both paths still depend on the printer not applying unwanted scaling.
