We convert physical sizes to inches, multiply by the selected DPI/PPI value, and round to whole pixels.
Quick answer
Copy-ready answer
Use 8.5 x 11 in for US letterhead. At 300 DPI, the trim size is 2550 x 3300 px; use A4 for metric-first business stationery.

Formula
How to calculate this size
215.9 mm x 300 PPI = 2,550 px wide.
Use this when the artwork stops at the finished edge.
Add 3.18 mm per side before calculating pixels when artwork reaches the edge.
Common mistakes
Avoid these print setup mistakes
If artwork reaches the edge, add bleed before export so small cutting shifts do not leave a white border.
Keep names, prices, QR codes, and calls to action inside the safe area, not directly on the trim line.
Close-viewed print usually needs 300 DPI; large signs and banners can use lower effective PPI when viewed from farther away.

Unlike flyers, letterhead often does not need full-bleed artwork. If the design uses a colored edge, watermark or background shape that reaches the paper edge, add bleed and export through a commercial print template. Leave generous margins for typed letters, signatures and scanning.
Workflow
Use Letterhead Print Size in a finished file
Set the finished product size before adding bleed or safe margin.
Extend backgrounds past trim and keep text inside the safe area.
Export PDF or raster files at the requested PPI and check crop marks before handoff.
