Envelope No. 6 3/4 at every resolution
A sheet of paper has no pixel size of its own. It has a physical size — 92.075 × 165.1 mm, or 3.63 × 6.5 inches — and a pixel count only appears once you choose how many pixels go in each inch.

What the file size means for Envelope No. 6 3/4
At 300 DPI an uncompressed Envelope No. 6 3/4 is 6.1 MB, and at 600 DPI it is 24 MB — four times as much, because doubling the resolution doubles both dimensions. That squaring is the reason large formats become unwieldy so quickly: the same 300 DPI that produces a manageable file at small sizes produces 6.1 MB here.
If a file is going to a printer, ask what they want before choosing. 300 DPI is the safe default and 150 is often enough for anything read from more than arm's length.
Setting up the canvas
Width: 1088 px
Height: 1950 px
Resolution: 300 pixels/inch
Colour: CMYK for print, RGB for screen
Bleed: 3 mm on every edge → 1158 × 2021 pxThe bleed figure is the one people forget: artwork that runs to the edge must extend 3 mm past it on all four sides, so the working canvas is larger than the finished sheet.
Frequently asked questions
What is Envelope No. 6 3/4 in pixels?
There is no single answer — it depends on the resolution. At the print standard of 300 DPI, Envelope No. 6 3/4 is 1088 × 1950 pixels. On screen at 72 DPI it is only 261 × 468.
What resolution should an Envelope No. 6 3/4 document be?
300 DPI for anything going to a commercial printer, which makes the canvas 1088 × 1950 pixels. 150 DPI (544 × 975) is acceptable for a draft or an internal document. Large formats read from a distance can go lower — a poster viewed from two metres looks sharp at 150 DPI, and dropping to it here saves 4.6 MB of file.
How big is an Envelope No. 6 3/4 file at 300 DPI?
About 6.1 MB uncompressed at 24-bit colour — 1088 × 1950 × 3 bytes. Compression brings that down a great deal for flat artwork and very little for a photograph, which is why a print-ready Envelope No. 6 3/4 PDF is usually tens of megabytes.
How many megapixels is Envelope No. 6 3/4 at 300 DPI?
2.1 megapixels. For comparison, Envelope No. 6 3/4 at 600 DPI is 8.5 MP — quadruple, because doubling the resolution doubles both dimensions.
