What US Trade 6×9 is for
6 × 9 inches is the default trim for a US trade paperback and the size almost every print-on-demand service lists first. It is the size most non-fiction is published at, holds around 300 words a page at a comfortable type size, and is the safe choice if you have no reason to pick another — a manuscript laid out for it will not need re-flowing when a printer is chosen.

Pixel dimensions depend entirely on the resolution you are working at — there is no single "pixel size" for a sheet of paper.

| 72 DPI | 432 × 648 | Screen preview only — far too coarse to print |
| 150 DPI | 900 × 1350 | Draft printing, internal documents |
| 300 DPI | 1800 × 2700 | The standard for commercial print |
| 600 DPI | 3600 × 5400 | Fine detail, line art, archival scanning |
