Print size · Stable Diffusion 1.5, square
How big can you print
a 512 × 512 image?
At 300 DPI, fine art standard
4.3 × 4.3 cm
1.7 × 1.7 inches
Drop the density and the print grows, at a cost you can see from a normal viewing distance.
| Density | Largest print | Use |
|---|---|---|
| 300 DPI | 4.3 × 4.3 cm | fine art, held in hand |
| 200 DPI | 6.5 × 6.5 cm | framed poster |
| 150 DPI | 8.7 × 8.7 cm | large format, seen from afar |
Every common print size, judged
The density shown is the one actually reached once the image is cropped to the format's aspect ratio. The short side decides, which is why a panoramic file fails a square print it looks big enough for. The last column is the enlargement needed to reach a true 300 DPI.

Questions people actually ask
How big can a 512 × 512 image be printed at 300 DPI?
4.3 by 4.3 centimetres, that is 1.7 by 1.7 inches. Divide each pixel count by 300 to get inches, then multiply by 2.54 for centimetres.
Is 512 × 512 enough for a poster?
Not at 300 DPI: at 4.3 by 4.3 centimetres the file is below every standard poster size. A poster needs the image enlarged first, or a density of 150 DPI accepted and viewed from a distance.
What does Stable Diffusion 1.5, square output mean for printing?
Stable Diffusion 1.5, square gives 0.3 megapixels. Print shops do not read megapixels, they read density at a physical size, and that is what the table above computes.
Get the file your print shop will accept
The workshop enlarges the image, sets the physical size and the density, adds the bleed, and hands back a file that is ready to send. Nothing here is guesswork: the numbers on this page are the ones it uses.
