Legal Paper Size: Dimensions and Letter Printing Options
US Legal is 215.9 × 355.6 mm. Check both the PDF and the loaded sheet before printing; choosing a paper name in software does not change the sheet in the tray.
| Unit | Portrait dimensions |
|---|---|
| Inches | 8.5 × 14 |
| Millimetres | 215.9 × 355.6 |
| PDF points | 612 × 1008 |
Work out the printable layout
A 14 inch page fitted into an 11 inch sheet is limited by height: 11 ÷ 14 = 78.57% before margins. A 12 point label scales to about 9.43 points, and a 100 mm reference becomes 78.57 mm. If the small text is hard to read, use supported Legal paper or rearrange the document across more pages.
Avoid a paper-size mismatch
Legal and Letter share an 8.5 inch width, but Legal is 3 inches (76.2 mm) longer. A tray may need a physical extension or a different feed path. The name Legal does not mean every legal document requires this size; follow the recipient’s actual format instructions.
A controlled print setup
- Inspect the PDF page dimensions, including pages that may have a different size within the same file.
- Confirm that your printer and selected tray support the sheet. Load it using the tray guides.
- For forms and measured printables, select Actual Size and disable any second driver scaling control. Content outside the printable area can still be clipped.
- Make one test copy. Check the top and bottom, then measure a known line before committing to a batch.
When the printer lacks this size
Use a supported sheet and deliberately redesign or scale the layout. Do not describe a scaled copy as actual size. If a document must retain dimensions, consider tiling or a printing service that supports the original sheet.
