15 x 20 Inches to Pixels
15 × 20 inches is 4,500 × 6,000 pixels at 300 DPI, 2,250 × 3,000 pixels at 150 DPI and 1,440 × 1,920 pixels at the 96 PPI screen standard.

15 × 20 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 | 1,080 × 1,440 | Legacy web |
| 96 DPI | 1,440 × 1,920 | Screen and CSS |
| 150 DPI | 2,250 × 3,000 | Posters and drafts |
| 300 DPI | 4,500 × 6,000 | Photo and magazine print |
| 600 DPI | 9,000 × 12,000 | 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 15 × 20 inches at 300 DPI that is 15 × 300 = 4,500 and 20 × 300 = 6,000.
The shape is 3:4, near enough to a 16 × 20 print that the two crop the same way.
A print at this size is usually seen from half a metre or more, where 150 DPI holds up, which puts it at 4,500 × 6,000 pixels at 300 DPI and 2,250 × 3,000 at 150.
That works out at 27 megapixels at 300 DPI, or 6.8 megapixels at 150 DPI. In metric the same size is 38.1 × 50.8 cm.
Frequently asked questions
How many pixels is 15 × 20 inches?
4,500 × 6,000 pixels at 300 DPI, 2,250 × 3,000 at 150 DPI and 1,440 × 1,920 at the 96 PPI screen standard. Multiply the inches by whichever density you are working to.
How many pixels is 15 × 20 inches at 300 DPI?
4,500 × 6,000 pixels. That is the standard density for photographic and magazine printing.
What is 15 × 20 inches in centimetres?
38.1 × 50.8 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 2,250 × 3,000 pixels rather than 4,500 × 6,000 — a quarter of the file for no visible loss.
Is 15 × 20 a 3:4 ratio?
Yes. That is 3:4, which is not a standard print shape: the closest is a Letter page, and fitting it means losing about 3% along the long edge.
How close is 15 × 20 inches to a 16 × 20 print?
a 16 × 20 print is 16 × 20 inches, so this is 1 in narrower and the same height. It fits inside with that much margin, so no scaling is needed.
