Why this size
4x6 Photo size in pixels, cm and inches
Printers think in physical sizes, screens think in pixels. 4x6 Photo is 10.16 x 15.24 cm, or 4 x 6 in. At 300 DPI, the standard for sharp prints, that is 1200 x 1800 px; at 150 DPI, enough for posters seen from a distance, it is 600 x 900 px.
The tool resizes your image to the 300 DPI size and writes 300 DPI into the file, so print dialogs pick the right size automatically. Print at 100% or Actual size, not Fit to page, and the result measures exactly 4 x 6 in.

Common problems and fixes
- The photo lab cut off part of the picturePhone photos are a different shape from 4x6 prints. Resize here with Fill and choose what to keep yourself, or use Fit to keep everything with thin borders.
- The print is darker than the screenScreens are lit from behind, paper is not. Brighten the photo a little before printing, especially faces in shadow.
- The print looks softStart from the original photo, not a screenshot or a copy sent through a chat app, which can have far fewer pixels.
- The shop prints 10 x 15 cmThat is 3% smaller than 4 x 6 inches, close enough for most frames. For an exact fit, ask for 4 x 6 inch prints.

We test the tool with sample photos before it goes live and check that the sizes on this page match what it produces. Rules and platforms change, so if something here is out of date, tell us and we will correct it.
How the tool works
The tool scales your image once, from the original pixels, to the size you set at 300 DPI, and writes 300 DPI into the file so it prints at that size. Everything happens in your browser; your images are never uploaded.
