It depends on your project. A business card is a very different size from a half-page magazine ad, as an example. We work within an eighth-inch (1/8″ or .125) margin on all four sides. For example, if you need business cards ordered, these are typically 3.5″ wide X 2″ tall (or vice-versa); the eighth-inch (1/8″ or .125) margin is added to all four sides, making the physical size of your artwork 3.625″ wide X 2.125″ tall.
