The Greeting Cards segmentation by application delineates the market into four principal uses: Birthday, Holiday, Thank‑You, and Other occasions. Birthday cards dominate, representing roughly 40 % of total sales, driven by universal cultural practices and high repeat purchase rates across age groups. Holiday cards, encompassing Christmas, New Year, and regional festivals, account for about 30 % of the market, reflecting seasonal spikes and promotional cycles that amplify volume. Thank‑You cards contribute an estimated 15 % as consumers increasingly use written appreciation in both personal and professional contexts, a trend reinforced by corporate gifting policies. The residual 15 % falls under Other, covering niche occasions such as anniversaries, graduations, and sympathy, which, while smaller in aggregate, exhibit steady growth through personalization trends. Collectively, these application segments shape demand patterns, inventory planning, and revenue distribution across the Greeting Cards market.
