Postcards vs Flyers: Understanding the Differences for Marketing Materials

When it comes to printing marketing materials, there are two main options: postcards and flyers. While many people associate these terms with specific sizes, the most important factor is their intended usage. This guide will explore the differences between postcards and flyers. We will look at their sizes, materials, and best practices for designing and printing them.


They must meet the size requirements set by the United States Postal Service (USPS). The size of these items is usually 4x6 inches. This size is convenient for mailing and can be used for other promotional activities. Postcards are typically printed on a thicker cardstock material to ensure durability during transit.


Flyers, on the other hand, are typically designed for mass distribution and disposable purposes. They are often printed in large quantities and made on thinner materials that are easier to fold and distribute. Flyers can be used for a variety of marketing purposes, such as door-to-door distribution or in-store promotions.

Rules Are Made To Be Broken

While postcards and flyers have their own general standards, these rules are not set in stone. There are instances where thinner materials may be used for postcards, or cardstock may be cut to custom sizes for flyers. The key is to know the size and purpose of your marketing material before beginning the design and printing process. At M3 Printing, we can help you create the perfect postcards or flyers for your marketing needs.
