There is no standard size for greeting cards; they come in various sizes. Common paper greeting card sizes include: Postcard size (148mm wide x 105mm high), standard greeting cards (e.g., large 175mm wide x 125mm high, medium 175mm wide x 95mm high, small 175mm wide x 85mm high), folded greeting cards (175mm wide x 250mm high), and square greeting cards (150mm wide x 150mm high). For better display, e-cards often use sizes such as 800 x 600 pixels (4:3 landscape) or 1920 x 1080 pixels (16:9 portrait). When printing greeting cards, bleed (usually 1.5mm) needs to be added to all four sides of the finished size. Folded greeting cards require additional treatment on the high edge to prevent misalignment.
Greeting card styles include invitation cards, Christmas cards, New Year's cards, postcards, birthday cards, Valentine's cards, holiday cards, Mother's Day cards, thank-you cards, and remembrance cards. The design materials are abundant, including traditional Chinese-style letter paper and holiday background templates.
Greeting card packaging design needs to balance aesthetics, emotional expression, and practicality. Excellent packaging should be visually appealing, attracting attention through harmonious color schemes and creative elements; it should accurately convey the emotions conveyed by the card's theme; and it should be protective, using sturdy or environmentally friendly materials to ensure the card remains intact during transport, and designed to be easy to open.
