Find mixed paper sizes before printing or merging
This analyzer reads each PDF page's media box and reports width, height, orientation and the nearest common paper size. It is useful for spotting one Letter page inside an A4 document, landscape pages, or unusual custom dimensions.
Paper-size names use a small tolerance because PDF dimensions can differ by a few points. Pages outside the tolerance are labeled Custom.
FAQ
Does this change my PDF?
No. This tool only reads page dimensions and creates an optional CSV report.
Which paper sizes can it recognize?
Common ISO A-series sizes plus Letter, Legal, Tabloid and Executive are recognized when dimensions are close to their standard values.
