Resize Image to 4x6 Inches
Prepare a standard 4 x 6 inch photo using the correct aspect ratio and pixel dimensions for draft or high-quality printing.
Standard photo proportions with predictable pixels
4:6 aspect ratio
Create the standard 2:3 photo shape in portrait or landscape orientation.
150 or 300 DPI calculation
Generate 600 x 900 pixels for draft output or 1200 x 1800 for common high-quality printing.
Crop or fit
Fill the complete print area or preserve every source pixel with background space.
4 x 6 pixel dimensions
| Setting | Result | Best use |
|---|---|---|
| 150 DPI | 600 x 900 px | Drafts and less demanding output |
| 300 DPI | 1200 x 1800 px | Common high-quality photo printing |
| Portrait | 4 inches wide by 6 inches tall | Portraits and vertical photos |
| Landscape | 6 inches wide by 4 inches tall | Scenery and horizontal photos |

How to resize a photo for 4 x 6 printing
A 4 x 6 print uses a 2:3 aspect ratio. At 300 DPI, the corresponding raster size is 1200 x 1800 pixels. At 150 DPI, it is 600 x 900 pixels. More pixels generally allow finer detail when the source image contains enough information.
Browser-generated files may not contain a reliable DPI metadata tag. The pixel dimensions are correct for the calculation, but you should still select 4 x 6 inches and disable unwanted printer scaling in the print dialog. Allow for lab-specific bleed or crop requirements.
Frequently asked questions
What pixel size is 4 x 6 at 300 DPI?
It is 1200 x 1800 pixels in portrait orientation or 1800 x 1200 in landscape.
Why might a print lab crop the edges?
Printers may enlarge slightly for borderless output or apply their own bleed and aspect-ratio rules.
Should I use crop or fit?
Use crop for edge-to-edge printing and fit when no source content can be removed.
Does this tool set physical print size automatically?
It creates the calculated pixels; select 4 x 6 inches in the printer or lab settings.
