Standard Postcard Sizes

Our commonly-printed addressed postcard sizes, USPSĀ® requirements, and important items to consider when choosing a postcard size.


Standard Postcard Sizes

When starting a postcard campaign, there are a few decisions to make early on. One is deciding what size postcard you would like to print and mail out to your recipients. 

Custom sizes are welcome, however, we have a handful of sizes that are the most common with our customers:

However, these are far from the only options you have when designing your postcard. The last thing we want to do at Excel Printing and Mailing is limit your creativity. We encourage you to have us print whatever size postcard you believe reflects your message.

However, to quality for letter size postage rates, there are four requirements from the United States Postal Service that you must follow when sizing your postcard. Each postcard must be: 

  • Rectangular
  • At least 3.5" tall x 5" long
  • No more than 6.125" tall and 11.5 long 
  • Between 0.007" and 0.25" thick (all our paper stock falls within this range)

So if you want a postcard that is 5.637" x 7.149", you can bet we'll print that for you... and commend your uniqueness. If you even want to mail out a 10" x 12" piece, that is also possible - it just may cost more for postage.

Many of our long-time clients like to regularly alternate sizes to keep their image fresh. We think this is a brilliant idea, just remember to keep your branding consistent across sizes.

There is one final thing to keep in mind when choosing your postcard size. A larger size, like 6" x 9" or 6" x 11" will likely attract more attention. However, there are cost savings when choosing a smaller size. When requesting a quote, feel free to ask us for two different size options so you can see the price difference.
