What Photo 8×12 is for
8 × 12 inches is the 2:3 enlargement — the size a full-frame or APS-C photograph prints at with nothing cropped, the same relationship 4 × 6 has at postcard scale. It is worth knowing because 8 × 10, the more commonly stocked frame, is 4:5 and does crop. If you are printing a composition you care about, 8 × 12 is the honest enlargement.

Photo 8×12 in pixels
Pixel dimensions depend entirely on the resolution you are working at — there is no single "pixel size" for a sheet of paper.
| Resolution | Pixels | Use |
|---|---|---|
| 72 DPI | 576 × 864 | Screen preview only — far too coarse to print |
| 150 DPI | 1200 × 1800 | Draft printing, internal documents |
| 300 DPI | 2400 × 3600 | The standard for commercial print |
| 600 DPI | 4800 × 7200 | Fine detail, line art, archival scanning |
Setting up a print document? Use 300 DPI and add 3 mm of bleed on every edge unless your printer specifies otherwise.
