Steps
Utilizing a Postage Calculator
Opt for a Forever stamp for most standard mail items. A single Forever stamp suffices to send off an item in a standard envelope measuring 11.5 inches (29 cm) by 5 inches (13 cm) and weighing 1 ounce (28 g) or less. Anything larger requires additional postage, which can be calculated using a postage calculator. The most convenient way to acquire specific postage is to purchase stamps online.

- As of July 2023, the price of a single Forever stamp is $0.66.
- Forever stamps are suitable for mailing letters, greeting cards, and paper items weighing less than 1 ounce (28 g).
- To send a standard commercial envelope outside the United States, a Global Forever stamp is necessary. Currently, Global Forever stamps cost $1.50 each.
For envelopes or packages exceeding standard size, use a ruler or measuring tape to determine dimensions. Measure length, width, and thickness for bulkier items. Postage costs are based on overall size.
- Take precise measurements; adjust as needed based on postage calculator instructions.
- Large packages require post office handling, not standard mail with stamps.
Weigh envelopes with gifts, photos, or extras using a sensitive scale. Kitchen scales work for small items; digital bathroom scales for heavier parcels.
- Postage calculators often round up weight for pricing.
- Without a scale, visit the post office for weighing and shipping.
Indicate the item’s mailing class—Ground, Priority, or First Class. Consider weight and delivery speed for choosing the appropriate class.
- Ground mail takes 2-8 business days, ideal for bulk and non-urgent items.
- Priority Mail guarantees delivery in 1-3 days; flat rate options available.
- First Class mail delivers in 1-3 days, limited to 13 ounces.
Use a postage price calculator to determine mailing costs. Input size, weight, class, and destination information. The calculator provides accurate postage costs for stamp calculation.
- US residents can use USPS’s online postage calculator.
- Ensure accurate information input for correct postage calculation.
Calculate stamps needed by dividing postage cost by the Forever stamp price. Round up for accurate postage, as fractions of stamps aren't usable.
- Alternatively, purchase additional stamps for postage differences.
- Various stamp values are available online for completing postage.
Apply your stamps properly. Remove the backing and affix the stamps to the envelope or package, preferably in the upper right corner or a visible area.
- Arrange stamps neatly without overlap.
- If needed, seek assistance from postal clerks for proper stamp application.
Take items needing multiple stamps to the post office. Large packages, overstuffed envelopes, and items over 13 ounces cannot be sent via residential mailboxes. Visit the post office and hand the item to an employee for processing.
- Postal clerks can assist with postage calculation and sell necessary stamps.
- In some areas, print shipping labels and schedule pickups from home to avoid visiting the post office.
Postage Calculation at the Post Office
Visit the post office with your sealed item. Ensure the envelope or package is securely sealed and correctly addressed, free from any confusing information.
- To save time, prepare and address your item before arriving at the post office.
- If supplies are low, purchase envelopes, mailers, and stamps online.
Weigh your item at the post office. Inform the staff that you need to determine the weight for postage calculation. They will weigh the item and provide the cost immediately.
- The clerk may request additional information such as postal codes and mailing preferences.
- Consider Priority Mail for faster delivery or First Class for cheaper rates, limited to items weighing 13 ounces or less.
Attach the necessary stamps to your item. Once the stamps are on your envelope or package, hand it to the postal clerk. At the post office, you can also pay for postage and have the clerk print a label indicating the shipping cost.
- Using your own stamps is more economical than paying for postage separately.
- If you're unsure about converting postage cost to stamps or prefer assistance, the postal clerk can help.
