How many postage stamps to mail a letter

The number of postage 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 or less):
  • Domestic: $0.55
  • International: $1.20
• First-Class Mail Letter (over 1 oz):
  • Domestic: $0.70 (for each additional ounce)
  • International: $1.20 (for each additional ounce)

For example, if you're mailing a letter that weighs 2 ounces, you would need:

• 2 x $0.70 = $1.40 in postage (for domestic mail)
• 2 x $1.20 = $2.40 in postage (for international mail)

You can also use a postage meter or a digital scale to weigh your letter and calculate the exact postage needed.

It's worth noting that you can also use Forever Stamps, which are always equal in value to the current First-Class Mail 1-ounce rate. This means that even if the rate increases in the future, your Forever Stamp will still be valid for mailing a 1-ounce letter.

If you're unsure about the postage needed for your letter, you can always check with your local post office or use an online postage calculator to get an estimate.
