How much postage to mail a 5x7 envelope

The cost of postage for a 5x7 envelope depends on the weight and destination of the mailpiece. Here are the current rates for First-Class Mail letters and flats:

• For a 5x7 envelope weighing up to 1 ounce:
  • Domestic (within the United States): $0.55
  • International: $1.20 (to Canada), $1.30 (to Mexico), and $1.40 (to other countries)
• For a 5x7 envelope weighing over 1 ounce:
  • Domestic (within the United States): $0.70 (for each additional ounce)
  • International: $1.20 (to Canada), $1.30 (to Mexico), and $1.40 (to other countries) + $0.15 (for each additional ounce)

Note that these rates are subject to change, so it's always a good idea to check the current rates on the USPS website or at your local post office.

Additionally, if you're mailing a 5x7 envelope to a specific country, you may need to use a Global Forever stamp, which costs $1.20. This stamp can be used to mail a 1-ounce letter or postcard to any country in the world.

It's also worth noting that if you're mailing a 5x7 envelope with extra items, such as a brochure or a small package, you may need to use a different type of postage, such as Priority Mail or Parcel Post.
