20 x 30 print planning
| Setting | Result | Best use |
|---|---|---|
| 100 DPI | 2000 x 3000 px | Distance-viewed wall posters |
| 150 DPI | 3000 x 4500 px | Balanced large-format output |
| 300 DPI | 6000 x 9000 px | Very large canvas with heavy memory use |
| 2:3 ratio | Same shape as 4 x 6 and 12 x 18 | Fits many camera compositions |

Export JPG or PNG; the safe-area guide is excluded.
Preparing a 20 x 30 wall print
A 20 x 30 print uses a 2:3 aspect ratio. At 150 DPI it is 3000 x 4500 pixels; at 300 DPI it becomes 6000 x 9000 pixels, a 54-megapixel canvas that can exceed memory limits on mobile devices.
Large wall prints are viewed from farther away, so 100 or 150 DPI may be practical depending on the printer and source. Keep essential content inside the guide and confirm bleed, frame overlap, and color requirements with the provider.
Frequently asked questions
What pixel size is 20 x 30 at 300 DPI?
It is 6000 x 9000 pixels in portrait orientation.
What aspect ratio is 20 x 30?
It simplifies to 2:3.
Is 150 DPI enough for a large wall print?
It can be appropriate at normal viewing distance, depending on the source and print method.
Why might 300 DPI fail on a phone?
A 6000 x 9000 canvas requires substantial memory for rendering and encoding.
