24×36 Print Size in Pixels
A 24 × 36 inch print needs 7200 × 10800 pixels at 300 PPI. It measures 60.96 × 91.44 cm and has a 2:3 aspect ratio.
24 × 36 in at 300 PPI: 7200 × 10800 px (77.8 MP)
At 240 PPI: 5760 × 8640 px · at 150 PPI: 3600 × 5400 px
24×36 in pixels at each density
Multiply each inch dimension by the density. The results are exact because both sides are whole inches.
| Density | Portrait | Landscape | Megapixels |
|---|---|---|---|
| 150 PPI | 3600 × 5400 | 5400 × 3600 | 19.4 |
| 200 PPI | 4800 × 7200 | 7200 × 4800 | 34.6 |
| 240 PPI | 5760 × 8640 | 8640 × 5760 | 49.8 |
| 300 PPI | 7200 × 10800 | 10800 × 7200 | 77.8 |

Nearest-pixel rounding can fall slightly below the target on one axis. Use Round up when the target is a strict minimum.
This is the canvas size. Changing a file’s PPI metadata alone does not create these pixels.

Will my photo fit 24×36 without cropping?
24 × 36 inches is a common poster size with a 2:3 proportion. At large sizes, viewers usually stand farther away; ask your printer what density they recommend for the size.
| Example source | Cropped pixels | Image kept | Density at 36 × 24 in |
|---|---|---|---|
| 3:2 camera frame6000 × 4000 px | 6000 × 4000 | 100% | 167 PPI |
| 4:3 phone frame4032 × 3024 px | 4032 × 2688 | 88.9% | 112 PPI |
| 16:9 video frame3840 × 2160 px | 3240 × 2160 | 84.4% | 90 PPI |
Example source sizes illustrate common proportions; enter your own dimensions in the crop calculator or image print checker.
How many megapixels does a 24×36 print need?
At 300 PPI the print needs 77.8 megapixels after any crop; at 240 PPI, 49.8 MP; at 150 PPI, 19.4 MP. These are arithmetic targets, not a promise of print quality: focus, noise and viewing distance matter too.
Changing an image’s PPI setting without resampling only changes its intended print size. Read what changing DPI actually does before upsizing a file.
