8.5 × 5.5 inches in pixels at every common resolution
The pixel count changes with the resolution you are working to — these are the values you are most likely to need.
| Resolution | Width × height in pixels | Typical use |
|---|---|---|
| 72 DPI | 612 × 396 | Legacy web |
| 96 DPI | 816 × 528 | Screen and CSS |
| 150 DPI | 1,275 × 825 | Posters and drafts |
| 300 DPI | 2,550 × 1,650 | Photo and magazine print |
| 600 DPI | 5,100 × 3,300 | Fine art and line work |
How the conversion works
Pixels are found by multiplying the length in inches by the pixel density: pixels = inches × DPI. For 8.5 × 5.5 inches at 300 DPI that is 8.5 × 300 = 2,550 and 5.5 × 300 = 1,650.
8.5 × 5.5 inches is exactly a half-letter sheet in landscape.
At 300 DPI that is a file of 2,550 × 1,650 pixels, which is what print shops ask for at a size handled this close.
That works out at 4.2 megapixels at 300 DPI, or 1.1 megapixels at 150 DPI. In metric the same size is 21.59 × 13.97 cm.
Frequently asked questions
How many pixels is 8.5 × 5.5 inches, a half-letter sheet in landscape?
2,550 × 1,650 pixels at 300 DPI, 1,275 × 825 at 150 DPI and 816 × 528 at the 96 PPI screen standard. Multiply the inches by whichever density you are working to.
How many pixels is 8.5 × 5.5 inches at 300 DPI?
2,550 × 1,650 pixels. That is the standard density for photographic and magazine printing.
What is 8.5 × 5.5 inches in centimetres?
21.59 × 13.97 cm, because one inch is exactly 2.54 centimetres.
Is 300 DPI the right density for this size?
Yes. At this size the finished piece is held or read close up, which is exactly what the 300 DPI standard is for — 2,550 × 1,650 pixels. Dropping to 150 halves that to 1,275 × 825 and the softening is visible in the hand.
Is 9 × 6 a 17:11 ratio?
Yes. That is 17:11, which is not a standard print shape: the closest is a 4 × 6 print, and fitting it means losing about 3% along the long edge.
Why does the pixel count change with DPI?
A pixel has no fixed physical size. The DPI value says how many pixels fill one inch, so raising it raises the pixel count needed to cover the same physical space.
