What is PDF Page Dimensions Analysis?

PDF page dimensions analysis involves examining the exact size, orientation, and proportions of each page in a PDF document. Every PDF page has specific width and height measurements that determine how it will display and print.

Why analyze PDF page dimensions?

  • Print Preparation: Ensure all pages are the correct size before printing
  • Document Standardization: Verify consistency across multiple documents
  • Design Planning: Understand exact dimensions for layout and design work
  • Quality Control: Identify pages with incorrect or inconsistent sizes
  • File Optimization: Detect oversized pages that increase file size
  • Compliance Checking: Meet specific dimension requirements for submissions

Key Measurements

  • ✓ Width and height
  • ✓ Orientation (portrait/landscape)
  • ✓ Aspect ratio
  • ✓ Standard paper size
  • ✓ Page area calculation
  • ✓ Rotation angle

Tabloid 11 × 17 in 279 × 432 mm Newspapers, newsletters

Frequently Asked Questions

You can view PDF page dimensions in four different units:

  • Points (pt): Standard PDF measurement unit (72pt = 1 inch)
  • Inches (in): Imperial measurement system
  • Millimeters (mm): Metric measurement system
  • Pixels (px): Based on 72 DPI (dots per inch)

You can switch between units at any time using the units selector above the results table.

Page orientation is determined by comparing width and height:

  • Portrait: Height is greater than width
  • Landscape: Width is greater than height
  • Square: Width and height are equal (rare)

Note: Some PDFs may have rotation metadata that affects how pages are displayed. We show both the physical dimensions and any applied rotation.

Currently, this tool analyzes one PDF at a time. For batch processing multiple PDFs:

  1. Analyze each PDF individually
  2. Export results to CSV for each file
  3. Combine CSV files in spreadsheet software
  4. Use filters and sorting to compare dimensions across documents

We're working on batch analysis features for future updates.

Mixed page sizes are common in PDFs, and our tool handles them perfectly:

  • Each page is analyzed independently
  • Results clearly show varying dimensions
  • You can sort by size to group similar pages
  • The summary section highlights inconsistencies

If you need to standardize page sizes, use our Fix Page Size tool.

Our measurements are highly accurate and based on the PDF specification:

  • Reads directly from PDF metadata
  • Precision to 3 decimal places
  • Accounts for PDF rotation values
  • Uses standard conversion formulas between units

For most practical purposes, the measurements are exact. Minor rounding may occur when converting between units.
