Design Tips
- →Keep body copy at 9 pt minimum on A6 — limited space makes type size critical. A single headline plus one key message works better than dense paragraphs.
- →A6 fits inside a C6 envelope (114 × 162 mm) exactly — design for 105 × 148 mm with 3 mm bleed, not the envelope dimensions.
- →For greeting card use, design A6 with a fold: print at A5 (148 × 210 mm) and score/fold at the centreline to produce an A6 folded card.
- →Use 300–350 gsm uncoated stock for premium greeting cards; 170–250 gsm silk or gloss for promotional cards that need to lie flat.
