How many stamps i need to mail a letter

The number of stamps needed to mail a letter depends on the weight and size of the letter, as well as the destination. Here are the current rates for mailing a letter in the United States:

• First-Class Mail Letter (1 oz):
  • Domestic: $0.55
  • International: $1.20
• First-Class Mail Letter (2 oz):
  • Domestic: $0.70
  • International: $1.45
• First-Class Mail Letter (3 oz):
  • Domestic: $0.85
  • International: $1.70

If your letter weighs more than 3 oz, you'll need to use a larger envelope or a package, and the cost will be higher.

To determine how many stamps you need, you can use the following formula:

• For a 1 oz letter: 1 stamp (=$0.55)
• For a 2 oz letter: 2 stamps (=$1.10)
• For a 3 oz letter: 3 stamps (=$1.65)

Keep in mind that these rates are subject to change, so it's always a good idea to check the current rates with the United States Postal Service (USPS) or on their website.

If you're unsure about the weight or size of your letter, you can also use the USPS's online postage calculator to get an estimate of the cost.
