Every detail matters in legal documents—from font type to paper size—to ensure they’re professional, clear, and easy to read.

If you’re unsure about what size paper you should use for a legal document, this guide breaks down everything you need to know about legal paper size (8.5 × 14 inches) step-by-step.

Legal paper size is 8.5 × 14 inches (216 × 356 mm). 

It’s longer than Letter and A4 paper, and many courts, law firms, and government offices require it for contracts, filings, and real-estate documents. If you’re preparing PDFs for legal use, choose Legal (8.5 × 14 inch) when printing or exporting.

Legal paper size measures 8.5 × 14 inches (216 × 356 mm), making it 3 inches longer than standard letter-size paper. This longer format sets it apart from letter-size paper, offering more versatility for complex legal documents.

Here are the key facts about legal paper size:

  • Standard in US and Canada - Part of the North American paper size series

  • ANSI paper size standards - Officially recognized format for government and legal use

  • Also known as “US Legal” - Distinguished from international paper sizes

Understanding the differences between these three common paper sizes helps you choose the right format for your documents:

Paper Size Comparison:

  • Legal Paper: 8.5 × 14 inches (216 × 356 mm) - North America

  • Letter Paper: 8.5 × 11 inches (216 × 279 mm) - North America

  • A4 Paper: 8.27 × 11.69 inches (210 × 297 mm) - International (ISO 216)

All three share similar widths, but legal paper provides the most length for detailed content. While letter and legal are both 8.5 inches wide, A4 follows different proportions entirely as part of the international ISO 216 standard.

Legal documents often need to communicate information clearly and concisely. The paper size for legal documents ensures there’s ample space for details like clauses, terms, and signature lines, all while maintaining standard formatting that courts and legal professionals recognize.

Legal paper’s extra length makes it ideal for:

  • Legal contracts: Multiple signature lines and detailed clauses

  • Court documents: Pleadings, motions, and briefs

  • Real estate papers: Deeds, titles, and property agreements

  • Government forms: Official applications and permits

Using the wrong size or type of paper can lead to confusion and may make your documents look unprofessional.
