How big can your AI export actually print?
Rough pixel-to-inch math after a 4x upscale. Use 150 DPI for large-format viewing distance; aim for 300 DPI when the piece will be seen up close.
| Typical AI export | After 4x upscale | Soft print (~150 DPI) | Close-view (~300 DPI) |
|---|---|---|---|
| ~1024 × 1024 | ~4096 × 4096 | ~27 × 27 in | ~14 × 14 in |
| ~1280 × 720 | ~5120 × 2880 | ~34 × 19 in | ~17 × 10 in |
| ~1536 × 1536 | ~6144 × 6144 | ~41 × 41 in | ~20 × 20 in |
| ~2048 × 2048 | ~8192 × 8192 | ~55 × 55 in | ~27 × 27 in |
These are approximate. Always confirm bleed, color mode, and vendor DPI with your print shop. Large-format posters viewed from several feet away can often run below 150 DPI; canvas and fine-art prints usually want more.
- Start from the native high-res download—not a Discord or social preview.
- Upscale the art plate first, then overlay vector type in your layout tool.
- Match DPI to viewing distance: posters can go softer than hand-held prints.
