Most modern playing cards come in two main sizes: poker size and bridge size. Poker size cards are about 2.5 × 3.5 inches (63 × 88 mm) and are the most common choice for games, magic and custom decks. Bridge size cards are slightly narrower at 2.25 × 3.5 inches (57 × 89 mm); many bridge and trick‑heavy games prefer this slimmer format because it is easier to hold a large hand of cards. When you design a custom deck of cards you almost always want poker size unless you have a special requirement. It is the size people expect when they think of a standard deck, and it gives your artwork a bit more room to breathe. CustomFaceCards is optimized for poker‑size printing with proper bleed, trim and safe areas, so your custom playing cards come out looking like a professionally printed deck – not a home‑made prototype. If you care about the exact dimensions because you are planning sleeves, accessories or comparisons with other decks, remember this rule of thumb: “poker size” = 63 × 88 mm, “bridge size” = 57 × 89 mm. Our custom deck builder uses a poker‑size layout behind the scenes so you can focus on uploading photos and choosing an art style while we handle the print‑ready layout for your custom deck of cards.
