Set the page before you export
Choose US Letter in your document editor before laying out the page. A portrait Letter PDF has a 612 × 792 point page box. If your printer defaults to A4, change the paper setting and confirm it matches the sheets in the tray.
Check Letter against A4 and Legal
Letter is wider and shorter than A4. Legal shares Letter’s 8.5 inch width but adds 3 inches of height. Select the correct format before comparing margins or page breaks.
