US Letter, 8.5 × 11 inches (215.9 × 279.4 mm), is the standard sheet in the United States, Canada, Mexico and the Philippines. Image editors and screens work in pixels, so the pixel size depends on resolution: this tool gives Letter at any DPI, in points for PDFs, and the printable area left inside your margins, with a comparison against A4, Legal and Tabloid.
How to use this tool
- Choose the resolution — 300 DPI for print, 96 for screen layouts.
- Pick portrait or landscape.
- Enter the page margin, in inches or millimetres, to see the usable area.
- Create your canvas in Photoshop, Canva or GIMP at the pixel size shown.
Formula
pixels = inches × DPI · mm = inches × 25.4 · points = inches × 72
Because Letter is defined in whole and half inches, its pixel sizes are exact at whole-number DPI values; only the metric sizes are conversions.
Example
At 300 DPI, 8.5 in × 300 = 2550 px and 11 in × 300 = 3300 px. With the usual 1-inch margins the text area is 6.5 × 9 in, or 1950 × 2700 px. As a PDF page Letter is 612 × 792 points.
