Question
What is the most popular brochure size for mailing?
Answer
For mailing, the 8.5 x 11 tri-fold is the runaway favorite. Folded, it measures roughly 3.67 x 8.5, which drops neatly into a standard #10 business envelope and keeps postage in the letter rate range.
- Flat size: 8.5 x 11, folded into thirds
- Folded footprint: about 3.67 x 8.5, sized for a #10 envelope
- Postage benefit: no custom envelope needed, which keeps mailing costs down
- Why it is default: works for direct mail across nearly every industry
