Blank playing cards are sold in several standard sizes: poker size (2.5" × 3.5" / 63 mm × 88 mm), bridge size (2.25" × 3.5" / 57 mm × 89 mm), square (2.75" × 2.75"), and tarot size (4.75" × 2.75" / 120 mm × 70 mm).
Common pack counts include 80, 162, 180, 200, and 240 cards.
Finishes commonly listed are matte and a slight gloss (aqueous) finish; some listings also describe a smooth cardstock surface.
Listings describe the cards as sturdy enough for shuffling and repeated gameplay. A center-core construction is often cited as helping cards 'pop' back into shape, and premium stock is noted to withstand extensive use.
Some blank cards have blank faces with patterned or decorative backs, while others are sold with no pre-printed designs on either faces or backs so you can fully customize both sides.
