- What size is A5 in mm?
- A5 is 148 × 210mm (5.8 × 8.3 inches) — exactly half of A4.
- What size is A6 in mm?
- A6 is 105 × 148mm (4.1 × 5.8 inches) — half of A5, about the size of a postcard.
- What size is DL?
- DL is 99 × 210mm — one third of an A4 sheet, which is why an A4 leaflet folded in three becomes DL.
- What size should my print file be?
- Add 3mm bleed to every edge, so the file is 6mm wider and 6mm taller than the finished size. An A5 file is 154 × 216mm. Keep text and logos at least 5mm inside the finished edge.
- How do A sizes relate to each other?
- Each A size is half the one before it: fold A4 in half and you get A5, fold A5 in half and you get A6.
