Photo 5×7 paper size
127 × 177.8 mm
5 × 7 inches · 12.7 × 17.78 cm · aspect ratio 1:1.4
Photo 5×7 size is 127 × 177.8 mm. Those are the Photo 5×7 dimensions a printer works to; the same sheet in centimetres, inches, points and pixels is below.
It is written 5x7 and 5 by 7 as often as 5×7 — the same sheet however it is typed. Sizes named by their inches like this one get asked for by the numbers rather than by a letter code, which is why the spelling varies and the sheet does not.
What Photo 5×7 is for
5 × 7 inches is a common frame size, but it is 5:7 rather than 2:3 — so a photograph straight out of a camera has to lose about 6% of its long edge to fit. Compose with that margin in mind if you know the shot is destined for a 5 × 7 frame, because the crop always comes off the ends.

Photo 5×7 in pixels
Pixel dimensions depend entirely on the resolution you are working at — there is no single "pixel size" for a sheet of paper. Photo 5×7 size in pixels has every resolution, with file sizes and canvas setup.
| Resolution | Pixels | Use |
|---|---|---|
| 72 DPI | 360 × 504 | Screen preview only — far too coarse to print |
| 150 DPI | 750 × 1050 | Draft printing, internal documents |
| 300 DPI | 1500 × 2100 | The standard for commercial print |
| 600 DPI | 3000 × 4200 | 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.
How Photo 5×7 relates to the rest of the series
At 127 × 177.8 mm (5 × 7 inches) the aspect ratio is 1:1.400. This size is not part of a halving series, so there is no fixed scaling factor to the next size up or down — each one is defined on its own terms.
The closest ISO sheet by area is A6 at 105 × 148 mm — this size is 45% larger. The proportions differ, though: A6 is 1:1.414 like every A size, and this one is 1:1.400, so content laid out for one does not fill the other without cropping or white space.
