Quick answer

## The short version

Choose the page size that suits the intended reading or printing workflow. A4 and Letter have different proportions, so the same photo and caption can occupy different areas. Neither is universally better. A familiar paper name does not establish that a particular printer accepts your PDF unchanged.

## Compare the workflows

| Decision | A4 portrait | US Letter portrait |
| --- | --- | --- |
| Proportions | Taller, narrower portrait proportion | Slightly wider portrait proportion |
| --- |
| Image placement | Depends on the image and caption | Depends on the same image and caption |
| --- |
| Decision check | Recipient or printer accepts A4 geometry | Recipient or printer accepts Letter geometry |
| --- |

## How to make the decision

Try one wide photograph and one text-heavy page in each size. Inspect the image’s placed size, caption wrapping and margins. Use the actual PDF page geometry when discussing a print order, and disable unintended scaling when checking an ordinary office proof. Memory Book Studio provides both page choices, but a new saved size change creates a different revision if exported. Review that decision before paying for multiple versions.

## Worked planning example

Planning example: A family sending a digital reading copy compares both sizes with its actual captions. A local printer later requests Letter, so the editor saves that size, checks all pages and exports the accepted revision instead of assuming a print dialog will preserve the original layout.

## Check before you finish

1. Check intended delivery requirements.
2. Test a wide and a text-heavy page.
3. Review actual PDF geometry.
4. Save the chosen size before export.

## Choose the next step for your task

Memory Book Studio saves a captioned photo story with fitted images, ordering and three fixed themes. Editing and previewing are free; exporting a new saved revision costs three account credits. Repeat downloads of that exported revision use no additional credits. Projects expire ten days after creation. Use the free Image to PDF tool when one image per page completes your task.
