What Mass Market is for
The mass market paperback is 4.25 × 6.87 inches, the rack-sized book sold in supermarkets and airports. It is smaller than a trade paperback in both dimensions, which forces either a smaller type size or more pages, and its narrow width leaves very little room for an inner margin once the fold is accounted for.

Mass Market in pixels
Pixel dimensions depend entirely on the resolution you are working at — there is no single "pixel size" for a sheet of paper. Mass Market size in pixels has every resolution, with file sizes and canvas setup.
| Resolution | Pixels | Use |
|---|---|---|
| 72 DPI | 306 × 495 | Screen preview only — far too coarse to print |
| 150 DPI | 638 × 1031 | Draft printing, internal documents |
| 300 DPI | 1275 × 2061 | The standard for commercial print |
| 600 DPI | 2550 × 4122 | 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 Mass Market relates to the rest of the series
At 107.95 × 174.5 mm (4.25 × 6.87 inches) the aspect ratio is 1:1.616. 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 21% larger. The proportions differ, though: A6 is 1:1.414 like every A size, and this one is 1:1.616, so content laid out for one does not fill the other without cropping or white space.
