ANSI C pixel dimensions by DPI
Pixel dimensions depend on output resolution. These values describe the trimmed page only and do not include printer bleed.
| Resolution | Pixel width | Pixel height | Typical use |
|---|---|---|---|
| 72 DPI | 1,224 px | 1,584 px | Screen preview |
| 96 DPI | 1,632 px | 2,112 px | Screen preview |
| 150 DPI | 2,550 px | 3,300 px | Draft print |
| 300 DPI | 5,100 px | 6,600 px | Quality print |
| 600 DPI | 10,200 px | 13,200 px | High-detail source |

Regional & printer note
Will a printer recognize ANSI C?
Used mainly in US engineering, manufacturing, and construction workflows. It requires a plotter or a printer designed for technical sheets.
Always match the document size, print-driver size, paper tray, and physical sheet. A driver can silently scale a page even when the preview looks correct.
