- 1200×1800 pixels prints at 4×6 inches at 300 DPI — a 2:3 ratio. Here is what else that file can print at, and where it stops being sharp.
- At 300 DPI it prints 4×6 inches. At 200 DPI it would stretch to 6×9 inches, with visible softening.
- 2:3.
- Up to about 6×9 inches at 200 DPI before softness becomes obvious. Beyond that you are upscaling and buyers will see it.
1200×1800 pixels prints at 4×6 inches at 300 DPI. The arithmetic is pixels ÷ DPI: 1200 ÷ 300 = 4 and 1800 ÷ 300 = 6.
| Printed at | Physical size | Verdict |
|---|---|---|
| 300 DPI | 4 × 6 in | Full quality. This is the size to sell. |
| 200 DPI | 6 × 9 in | Usable, slightly soft close up. |
| 150 DPI | 8 × 12 in | Noticeably soft. Not worth selling. |
What ratio you are working with
1200×1800 is a 2:3 ratio. That determines which standard print sizes this file can fill without cropping, and it is the number worth knowing — a file's ratio travels across every size, its pixel count does not.
If you need it bigger
- Rebuild at the larger size if the artwork is vector or you still have the source.
- Upscaling adds pixels but no detail. On matte paper it is obvious.
- If the file is fixed, list the sizes it genuinely supports rather than the sizes you wish it did.
