48 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 | 3,456 | Legacy web |
| 96 DPI | 4,608 | Screen and CSS |
| 150 DPI | 7,200 | Posters and drafts |
| 300 DPI | 14,400 | Photo and magazine print |
| 600 DPI | 28,800 | 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 48 inches at 300 DPI that is 48 × 300 = 14,400.
48 inches is a single edge, so the density alone decides the pixel count.
A print at this size is seen from several metres, where 72 DPI or less is normal practice, which puts it at 14,400 pixels at 300 DPI and 7,200 at 150.
In metric, 48 inches is 121.92 cm or 1,219.2 mm, and in typographic units it is 3,456 points.
Frequently asked questions
How many pixels is 48 inches?
14,400 pixels at 300 DPI, 7,200 at 150 DPI and 4,608 at the 96 PPI screen standard. Multiply the inches by whichever density you are working to.
How many pixels is 48 inches at 300 DPI?
14,400 pixels. That is the standard density for photographic and magazine printing.
What is 48 inches in centimetres?
121.92 cm, because one inch is exactly 2.54 centimetres.
What density should something this large be built at?
Far less than 300. At this size the viewer is several metres away, where 72 DPI or less is normal practice — 3,456 pixels. Large-format files are often built at quarter scale and enlarged on the RIP.
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.
