The card size refers to the dimensions (width and height) of the paper. The North American Standard is 3.5”x2” however we can custom cut cards to suite your needs. Please note that odd sized cards are priced differently and it is recommended that you email your design file into sales@rockdesign.com for custom pricing. For invitations there is not standard size however the most common sizes are 4”x6” and the 5”x7”.
