US Letter is 8.5 x 11 inches, so pixel dimensions are direct DPI multiples.

The page is useful when a scanner, form or document workflow asks for Letter-sized image output.

Common use cases

  • Planning worksheet image exports
  • Checking form upload dimensions

Print notes

  • Letter at 300 DPI is 2550 x 3300 pixels.
  • Use 150 DPI for lighter preview images when print quality is not required.
  • Margins and bleed are not included in the raw paper size.

Original test sample

  • Set Letter to 300 DPI and confirm 2550 x 3300 pixels.
  • Use the image resizer next if your source image needs to match the result.

Frequently asked questions

Are my images uploaded?

No. ImgShrink processes selected images in your browser and does not upload them to a server.

Which DPI should I use?

300 DPI is a common high-quality print target, 150 DPI can work for general print, and 72 or 96 DPI is mainly screen-oriented.

Is this a final print or document approval check?

No. The calculator gives pixel, DPI and physical-size math. Printers, passport offices and upload portals may apply extra rules.

Source and compatibility notes

DPI and print-size results use standard pixel-to-physical-size formulas. Document-photo presets are reference sizes, not a substitute for official submission rules.
