Most photo problems are easier to prevent than to repair. The capture conditions matter long before the crop is opened in an editor.

Design the output around the paper

For physical photos, the paper is the canvas. Decide the finished photo dimensions, number of copies, spacing and safe margins before exporting the sheet. Then make sure the print dialogue does not rescale the page.

A small test prevents a large reprint

Measure one printed copy after the first run. If it is larger or smaller than intended, stop and correct the scale setting before printing the entire sheet. “Fit to page” is convenient for ordinary documents but can change the physical size of an ID photograph.

Why 4×6 is useful

A 4×6 inch print is a compact photo-lab format. The useful question is not only how many copies can fit, but whether the chosen dimensions leave realistic cutting space and match the paper size actually being used.

Keep the layout stable

Build the sheet once, export it at the intended dimensions and avoid applications that silently rescale the image during printing.

Your master is the valuable asset

The original portrait is the version worth preserving. Application-ready files are derivatives; keep them separate so one future requirement does not force you to reshoot or re-edit from a low-quality copy.

The physical result deserves its own quality check

When the final output is a print sheet, check one physical copy rather than trusting the preview alone. A printer can introduce scaling, border expansion or colour shifts that are invisible in the exported PDF or JPEG. A small ruler or a known reference measurement can confirm the actual dimensions before you produce the full batch.

What to remember from this page

For a family or multi-document job, label each output with both person and destination. It takes seconds and prevents mix-ups when several similar photographs are sitting in the same folder.

One last check: Read the upload field’s help text as well as the general guidance; the upload field often exposes the exact file constraints the system will enforce.

Use the Studio for production and the issuing authority for the rule. That separation keeps the workflow practical and honest.
