Sizes vary from very small novelty cards up to standard poker dimensions. Examples shown include about 2-1/4" x 1-1/2" (very small novelty), a mini size around 2.5" x 1.75", and standard poker size at 2.5" x 3.5".
Mini cards are typically made from cardstock or heavy-coated card stock. Common finishes include matte writing surfaces for blank cards and laminated front-and-back finishes for reusable dry-erase cards.
Mini blank cards accept permanent pens and markers. Laminated reusable cards are intended for dry-erase (and in some listings wet-erase) markers and can be wiped clean for reuse.
Packaging varies by set size: some mini decks come individually packaged in clear plastic reusable storage containers, while larger or reusable sets are packed in tuck boxes.
“Poker size” refers to the standard card dimension of about 2.5" x 3.5". “Mini size” denotes a smaller card with the same proportions but reduced height—examples shown include roughly 2.5" x 1.75" and very small novelty sizes like 2-1/4" x 1-1/2".
Mini blank cards are used for crafting and custom games and are also popular as small fillers or favors—for example, in goodie bags, reward buckets, birthday parties, and piñatas.
One reusable dry-erase option shown is poker size (about 2.5" x 3.5") and is offered as a 180-card set packaged in a tuck box.
