A sheet of paper has no pixel size of its own. It has a physical size — 120.65 × 165.1 mm, or 4.75 × 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 A6 Envelope (US)
At 300 DPI an uncompressed A6 Envelope (US) is 8.0 MB, and at 600 DPI it is 32 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 8.0 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

Height: 1950 px
Resolution: 300 pixels/inch
Colour: CMYK for print, RGB for screen
Bleed: 3 mm on every edge → 1496 × 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.
