Question
What size is standard letterhead?
Answer
Standard letterhead size depends on where you are. In the United States it is letter size, while countries using international paper standards use A4. Both are designed to run through everyday office printers without trimming.
| Region | Size name | Dimensions |
|---|---|---|
| United States | Letter | 8.5 in x 11 in |
| International (ISO) | A4 | 8.27 in x 11.69 in |
- Letter size is the default for most US business documents.
- A4 is slightly narrower and taller than letter, so a design built for one is not a perfect fit for the other.
- Confirm the size with your printer before designing so your margins and logo placement land correctly.
