24 x 36 Inches to Pixels
24 × 36 inches is 7,200 × 10,800 pixels at 300 DPI, 3,600 × 5,400 pixels at 150 DPI and 2,304 × 3,456 pixels at the 96 PPI screen standard.

24 × 36 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 | 1,728 × 2,592 | Legacy web |
| 96 DPI | 2,304 × 3,456 | Screen and CSS |
| 150 DPI | 3,600 × 5,400 | Posters and drafts |
| 300 DPI | 7,200 × 10,800 | Photo and magazine print |
| 600 DPI | 14,400 × 21,600 | 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 24 × 36 inches at 300 DPI that is 24 × 300 = 7,200 and 36 × 300 = 10,800.
24 × 36 inches is a large poster size.
Hung and read from about a metre away, 150 to 200 DPI is indistinguishable from 300, so 3,600 × 5,400 pixels is usually all it needs rather than the 7,200 × 10,800 a 300 DPI file would carry.
That works out at 77.8 megapixels at 300 DPI, or 19.4 megapixels at 150 DPI. In metric the same size is 60.96 × 91.44 cm.
Frequently asked questions
How many pixels is 24 × 36 inches, a large poster size?
7,200 × 10,800 pixels at 300 DPI, 3,600 × 5,400 at 150 DPI and 2,304 × 3,456 at the 96 PPI screen standard. Multiply the inches by whichever density you are working to.
How many pixels is 24 × 36 inches at 300 DPI?
7,200 × 10,800 pixels. That is the standard density for photographic and magazine printing.
What is 24 × 36 inches in centimetres?
60.96 × 91.44 cm, because one inch is exactly 2.54 centimetres.
Does this size really need 300 DPI?
Usually not. Something this size is read from about a metre away, and at that distance 150 to 200 DPI is indistinguishable from 300. That is 3,600 × 5,400 pixels rather than 7,200 × 10,800 — a quarter of the file for no visible loss.
Is 24 × 36 a 2:3 ratio?
Yes, and 2:3 is the shape of a 4 × 6 print, so it fills one edge to edge with nothing cropped.
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.
