9 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 | Pixels | Typical use |
|---|---|---|
| 72 DPI | 648 | Legacy web |
| 96 DPI | 864 | Screen and CSS |
| 150 DPI | 1,350 | Posters and drafts |
| 300 DPI | 2,700 | Photo and magazine print |
| 600 DPI | 5,400 | 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 9 inches at 300 DPI that is 9 × 300 = 2,700.
9 inches is a single edge, so the density alone decides the pixel count.
A print at this size is held or read close up, where 300 DPI is the density to work to, which puts it at 2,700 pixels at 300 DPI and 1,350 at 150.
In metric, 9 inches is 22.86 cm or 228.6 mm, and in typographic units it is 648 points.
Frequently asked questions
How many pixels is 9 inches?
2,700 pixels at 300 DPI, 1,350 at 150 DPI and 864 at the 96 PPI screen standard. Multiply the inches by whichever density you are working to.
How many pixels is 9 inches at 300 DPI?
2,700 pixels. That is the standard density for photographic and magazine printing.
What is 9 inches in centimetres?
22.86 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 — 2,700 pixels. Dropping to 150 halves that to 1,350 and the softening is visible in the hand.
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.
