Common pack sizes for kids' blank card sets include mid-size counts such as 36 and 48 cards, with larger assortments available up to about 144 cards.
Most kids' blank card sets use a 4 × 6 inch format, while some child-focused sets use a slightly larger 5.5 × 4.25 inch size.
Cards are typically printed on sturdy 250gsm cardstock that provides a durable, smooth writing surface. Matching envelopes are often made from about 120gsm paper.
Many packs have fully blank interiors for freehand messages or photos, while some kids' cards use simple fill‑in‑the‑blank layouts to guide young writers.
Common designs include colorful motifs and playful illustrations (unicorns and other child‑friendly art), bright rainbow colorways, and occasional foil or metallic accents for extra polish.
Variety varies by pack: some assortments include about six designs, others eight, and larger bulk sets list up to roughly 18 unique designs.
These cards are commonly used for birthdays and thank‑you notes, classroom or party handouts, and some collections are tailored for milestones such as baby showers or bar/bat mitzvahs.
The cards provide a blank canvas for photos, handwriting, and crafts—suitable for markers, stickers, stamps, and attaching printed photos or other creative embellishments.
