What product should I use to print playing card size (2.5x3.5 inches)?

For playing card or trading card size at 2.5" x 3.5", the dedicated Trading Cards product is the right choice, since it is offered at exactly that dimension.

• Trading Cards: built for the 2.5" x 3.5" playing card format.
• Standard custom business cards: do not cover this specific dimension, so they are not the fit here.
• Finishes: trading card stock and coatings are suited to the shuffling and handling that cards get.

If you are printing a deck, game cards, or collectibles at that size, start with the Trading Cards product rather than trying to force a business card size.
