Postage Cost of Greeting Cards | Overview

When sending greeting cards through USPS, a typical card can be mailed for the cost of 1 postage stamp.

Note on Greeting Cards and Rates

In 2022, a 1-oz First-Class Mail postage stamp costs $0.60 at the Post Office. Look up the postage stamp retail rate.

Smaller greeting cards that do not require envelopes (measuring min. 5" L, 3.5" H, 0.007" thick, and max. 9" L, 6" H, 0.016" thick) may also be eligible for postcard pricing. In 2022, a First-Class Mail postcard stamp costs $0.44 at the Post Office.

ShippingEasy partners with Stamps.com to provide First-Class Mail letter postage in 1-ounce increments, up to 3.5-ounces. Learn how to purchase a First-Class Mail letter stamp.

  • Add a stamp for each ounce the card weighs. Be sure to round up. For example, a card that weighs 1.5 ounces would get two stamps.

  • Additional charges may apply if the card is non-machinable, rigid, or oversized. If unsure, we recommend using ShippingEasy or your local post office provider to avoid mismailing.

Besides the weight of the card, there are a couple of potential charges that might affect the price of your postage:

  • Non-machinable surcharge

  • "Rigid" letter-size pricing

Non-Machinable Greeting Cards

The Non-Machinable Surcharge applies to First-Class Mail letters that cannot be processed automatically, such as envelopes that are too large, too small, too thick, or mislabeled. Letters that cannot be processed using standard sorting machines must be sorted by hand. For instance, square greeting cards often do not fit in standard sorting equipment. Learn more about USPS non-machinable surcharges.

As of August 2021, USPS's non-machinable surcharge for First-Class Mail is $0.30.

Remember that cards sent as a "large envelope/flat" are not subject to the non-machinable surcharge. Learn more about First-Class Mail flats.

“Rigid” Letter-Size Pricing

Greeting cards can be classified as “rigid” if they cannot flex at least 1-inch and is less than:

  • 11-1/2" x 6-1/8" x 1/4" thick

  • 3.5 ounces

If letters meet these conditions, they will be charged the standard postage rate, plus a non-machinable surcharge. Find out how USPS determines flexibility.

If greeting cards exceed these dimensions, they will be priced as a "large envelope/flat". Learn more about First-Class Mail flats.

Sending Oversized Greeting Cards

It may be possible to send an oversized greeting card as a letter by folding it smaller. To do so, fold it gently and seal it with wafer glue, sealing glue, or tape.

Be sure to avoid mailing issues by checking that:

  • The adhesive does not interfere with the barcode or mailing address.

  • The letter falls within the acceptable sizes for folded self-mailers:4-1/4” x 6” minimum up to 6-1/8” x 10-1/2” maximum.

  • Learn more about USPS limits for letter dimensions.
