Photo 8×10 paper size

203.2 × 254 mm

8 × 10 inches · 20.32 × 25.4 cm · aspect ratio 1:1.25

Photo 8×10 size is 203.2 × 254 mm. Those are the Photo 8×10 dimensions a printer works to; the same sheet in centimetres, inches, points and pixels is below.

It is written 8x10 and 8 by 10 as often as 8×10 — 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 8×10 is for

8 × 10 inches is the portrait and framing standard at a 4:5 ratio, which is a considerably tighter crop from a 2:3 original than 5 × 7 — around 17% of the long edge has to go. This is the size most portrait photographers compose for deliberately, leaving headroom that will survive the crop, and it is also the classic large-format negative size the ratio comes from.

Photo 8×10 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 8×10 size in pixels has every resolution, with file sizes and canvas setup.

Setting up a print document? Use 300 DPI and add 3 mm of bleed on every edge unless your printer specifies otherwise.

How Photo 8×10 relates to the rest of the series

At 203.2 × 254 mm (8 × 10 inches) the aspect ratio is 1:1.250. 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 A4 at 210 × 297 mm — this size is 17% smaller. The proportions differ, though: A4 is 1:1.414 like every A size, and this one is 1:1.250, so content laid out for one does not fill the other without cropping or white space.
