What ARCH E is for
ARCH E is 36 × 48 inches — four ARCH C sheets, and the largest size in the series. Large commercial and civil sets are plotted at E because a site plan at a usable scale simply will not fit on D. Its practical limits are physical rather than graphical: a 36-inch plotter roll is the widest most offices own, and an E sheet folded for a binder is bulky enough that many firms issue E for the archive and a half-size print for the field.

ARCH E in pixels
Pixel dimensions depend entirely on the resolution you are working at — there is no single "pixel size" for a sheet of paper.
| Resolution | Pixels | Use |
|---|---|---|
| 72 DPI | 2592 × 3456 | Screen preview only — far too coarse to print |
| 150 DPI | 5400 × 7200 | Draft printing, internal documents |
| 300 DPI | 10800 × 14400 | The standard for commercial print |
| 600 DPI | 21600 × 28800 | 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.
