The number of stamps needed to send a letter depends on several factors:
1. Destination
- Domestic (within the same country): Usually requires fewer stamps.
- International: Requires more postage, often multiple stamps or a higher-value stamp.
2. Weight and Size of the Letter
- Standard letter (up to 1 ounce in the US): Typically requires one "Forever" stamp.
- Heavier letters: Additional postage is needed for each ounce over the limit.
- Non-standard sizes or shapes: May require extra postage.
3. Postal Service and Rates
- Rates vary by country and postal service.
- In the US, as of 2025, one Forever stamp covers the first ounce for a standard letter.
- Additional ounces cost extra (e.g., 24 cents per ounce over 1 oz).
Example: Sending a Letter in the United States
- Up to 1 oz: 1 Forever stamp (currently $0.66)
- Each additional ounce: Add 24 cents (or additional stamps totaling that amount)
- Non-machinable surcharge: May apply for odd sizes or rigid envelopes
How to Check Exact Postage
- Visit your country’s postal service website (e.g., USPS.com for the United States).
- Use a postage calculator by entering weight, size, and destination.
- Buy stamps accordingly or use postage meters/online postage services.
