How to Analyze PDF Page Ratios
This checker compares each page width with its height and reports the aspect ratio. It helps identify inconsistent page proportions before printing, resizing, merging or exporting PDF documents.
Example
An A4 portrait page has a width-to-height ratio close to 0.707. If one page in the same document reports a much larger value, it may be landscape or use a different page size.
Factors That Affect the Result
The ratio reflects page dimensions only. Rotation settings, crop boxes and mixed page sizes can influence how pages appear in a viewer, so use the ratio together with orientation and page-size checks.
Frequently Asked Questions
What does a ratio above 1 mean?
The page is wider than it is tall.
Does this tool resize pages?
No. It only analyzes dimensions.
Can one PDF contain different ratios?
Yes. Each page is measured separately.
Technical Details and Limitations
A PDF page aspect ratio compares page width with height. Pages with the same ratio can still have very different physical sizes, and rotation can swap the apparent ratio, so ratio analysis should be interpreted alongside page dimensions.
Technical Details and Practical Limits
Aspect ratio compares page width with height, independent of physical size. Two pages can share the same ratio while having different dimensions, and rotation can invert the apparent width-to-height relationship.
