About This Tool
ToolsFaction PDF Page Size Checker is useful when a document mixes A4, Letter, landscape sheets or custom canvas sizes. It reads each page, converts dimensions to your preferred unit and can reduce the list to unique sizes for faster auditing.
How to Use
- Choose a PDF file.
- Select the unit and whether to show every page or unique sizes.
- Analyze the document to inspect dimensions and orientation.
- Download the full page-size report as CSV if needed.
Example
Audit a 200-page print file to find the few pages that were exported as Letter instead of A4.
