How much to mail 5 ounces first class

According to the United States Postal Service (USPS), the cost to mail a 5-ounce letter or package using First Class Mail is as follows:

• Domestic (within the United States):
  • Flat Rate Envelope (up to 5 oz): $3.50
  • Weight-based rate (5 oz): $0.95
• International (to Canada, Mexico, and other countries):
  • Flat Rate Envelope (up to 5 oz): $13.25
  • Weight-based rate (5 oz): $2.95

Please note that these rates are subject to change, so it's always a good idea to check the USPS website or consult with a postal worker for the most up-to-date information.

Additionally, if you're mailing a package that weighs more than 5 ounces, you'll need to use a different type of mail service, such as Priority Mail or Parcel Post, which have different rates and requirements.
