3:4 Cropping Tips

Paper-format cropping (3:4) requires accounting for print bleed margins — typically 3mm per edge — so the actual visible area is slightly smaller than the full crop. Standard paper ratios (A-series uses 1:√2, US Letter is 1:1.294) are optimized for reading documents rather than displaying photos, so check whether your composition works in this format before committing.

Print lab flexibility: Most labs accept slight ratio variations, so a near-match is usually fine. For exact compliance, set the crop to 3:4 here, then resize to the precise pixel dimensions your printer requires. If you are creating a printable document, export via the PDF tool for print-ready output.
