If you’ve ever received a postcard in the mail, you’ve probably noticed how small and compact they are, compared to a normal sized letter or envelopes. The great thing about postcards is that they’re able to convey lots of information in a clear and compact way. They make perfect refrigerator decorations, and they’re an easy way to send someone a quick note from a faraway place.

Postcards can also be a very cost-effective print marketing tool. They allow your business to reach a large number of prospective customers at a low cost. Advertising postcards can also be more effective than traditional direct mail because people don’t have to tear open an envelope, unfold the letter and read it. In fact, once people realize a letter is direct mail, most discard it without ever opening it.

With a postcard, all people have to do is flip it over and read your quick message on the back. Better yet, put branded content on both sides when you utilize double sided printing. Even when they know the postcard is direct mail, their curiosity outweighs the minimum effort, so they flip it over and read it – mission accomplished!

If you’re thinking about printing some postcards to announce a special promotion or simply build brand awareness, you want to make sure to use the right size. In which case you’re probably wondering, “What are the dimensions of a postcard?”

What Is The Standard Postcard Size?

The standard postcard size is 4” x 6” or 5 x 7”. (For marketing purposes, there’s a real advantage to 4 x 6 postcards which we will tell you about shortly.) But most printing companies can accommodate many different dimensions of postcards, depending on the design. This article will help you better understand what the standard size of postcards is.

Although 4” x 6” and 5” x 7” are the most popular postcard dimensions, a postcard can be as small 3.5″ x 5″ to as big as 6.125″ x 11.5″ and everything in between. A postcard that fits within those dimensions and is less than .25” thick can be processed as a postcard by the U.S. Postal Office.

If you want a bigger postcard size for a marketing mailing, it will cost more. Common larger postcard dimensions include:

  • 4″ x 9″
  • 5.5″ x 8″
  • 6″ x 11″

These bigger dimensions allow for long messaging and more flexibility of design on the cover.

When using a larger postcard, check to make sure your printer can handle the size you want before investing the time and effort in designing your card. At Printivity, we offer numerous dimensions, however these are six different larger postcard dimensions:

  • 4” x 6”
  • 5.5” x 8.5”
  • 5” x 7”
  • 6” x 9”
  • 6” x 11”
  • 8.5” x 11”

Our website also offers downloadable templates for each size to help you with the design.

Postcard dimensions determine the cost of mailing

For the U.S. Postal Service to charge the lower postcard rates, the size of a postcard must meet specific requirements. First, it must be rectangular in shape. Different sizes are okay; different shapes are not. Then the postcard must be at least 3.5” x 5 inches and 0.007” thick. At the same time, it can’t be larger than 4.25” x 6” and 0.016” thick. If your mailer doesn’t fit within these postcard dimensions, the U.S. Postal Service considers it a letter and will charge letter-size postage. This is what makes the 4” x 6” a good choice for marketing postcards. It fits within the guidelines for the low postcard rates, whereas the 5” x 7” does not.

With USPS Marketing Mail services, size isn’t an issue because the U.S. Postal Service doesn’t charge a lower price for these types of postcards. USPS Marketing Mail is a category of mailing for businesses that want to send out large quantities of mail at the lowest cost. To qualify for Marketing Mail’s bulk pricing, the mailing must have a minimum of 200 pieces or 50 pounds of mail. There is no single-piece USPS Marketing Mail postage.

It doesn’t matter if your postcard is too big or too small; all Marketing Mail is charged at letter prices. The only exception are postcards bigger than 6.125″ x 11.5″ or more than .25″ thick. Any mailer this size or bigger will be charged large envelope postage prices.
