Design Tips
- A6 matches the postcard format recognized by postal services internationally. Check your country's postal size limits for exact mailing requirements.
- At this compact size, use a minimum font size of 8 pt for body text to maintain readability.
- Four A6 cards can be printed on a single A4 sheet — efficient for short-run postcard or invitation printing.
- At 300 DPI (1240 × 1748 px), A6 files are tiny. Always use 300 DPI or higher to ensure crisp output at close viewing distances.
Setting Up A6 Files
Create your A6 document at 105 × 148 mm with 3 mm bleed in your design tool of choice. Adobe InDesign, Illustrator, and Canva all support A6 as a preset. For postcards and invitations, print shops often accept PDF files at this size. In Figma, the Print for Figma plugin includes a built-in A6 preset with bleed setup and CMYK export, making it straightforward to design small-format print pieces collaboratively.
