PDF consistency

Mixed PDF page size checker

Find pages that differ from the rest of a PDF before they trigger scaling, cropping or paper changes.

Use the private PDF checker

The main checker reads every page locally, labels standard paper sizes and reports whether the document contains mixed dimensions.

Common causes

  • Merged files from different applications
  • Scans captured on different paper settings
  • A cover page designed in a separate template
  • A4 and US Letter documents combined together

What to do when sizes differ

Decide whether the variation is intentional. If every page should match, correct the source document or use a trusted PDF editor to resize pages. PrintSpecLab reports the issue but does not modify the file.

Also check mixed portrait and landscape pages and read the PDF page size guide.
