Leaflet or flyer (also spelt as flier) is a small- or medium-sized piece of paper, one-sided or double-sided, and often with an advertising or informative purpose. The most common is A6 format (10.5 x 14.8 cm in size). A flyer should present the basic information about your company and products or services you offer. It must not be overcrowded with information and colors because it leads to a counter-effect. An effective flyer with a simple but striking design leaves the best impression on your prospective clients.
