How to Send a Letter
1. Measure Your Envelope
For a standard letter (under 3.5 ounces), your envelope must be a minimum 5” x 3.5”, maximum 11.5” x 6+⅛”, and no thicker than 1/4". Most smaller thank-you cards meet the minimum and larger greeting cards are under the maximum, as seen below.
Make sure your envelope is of uniform thickness, rectangular, and bendable. Otherwise, you may have a "non-machinable" envelope and add $0.40 of extra postage. Check out the full list of non-machinable characteristics.
Square envelopes must be a minimum of 5". Square envelopes are considered non-machinable so add the extra $0.40. If you don't add the $0.40 extra, the USPS may return your envelope back to you.
2. Weigh your letter
Use a kitchen food scale to check your envelope’s weight. If you don’t have a scale, Amazon makes a good entry level scale for $12.59 or Walmart sells several inexpensive kitchen scales like this Milleroo scale for $13.36.
Round up to the nearest ounce. For example, if your letter weighs 1.21 ounces, you will need postage for 2 ounces. Apply the correct number of stamps per ounce (See stamps per ounce).
If you're sending printed photos, check out our guide on how many stamps are needed to mail 4x6 photos — no scale needed!
3. Address Your Envelope and Add Stamps
A return address typically goes in the upper-left of your envelope and is not required. Your recipient's address should go in the center of the envelope. Stamps go in the upper-right corner of a letter, ideally all in one row. However, the post office will accept your letter even if your stamps go to a second or third line.
Where to Buy Stamps
You can buy stamps at your local USPS post office and online at USPS.com — shipping is just over $1 for a sheet of stamps. Walmart and Amazon also carry stamps, as well as many local banks. Stamps from Amazon aren't a very good deal at $16.18 for a sheet of 20 which you can get for $5.18 less direct from the USPS.
Delivery Speed for Letters to Hong Kong
Unlike domestic letters which are delivered in 1-3 days, delivery time to Hong Kong is 7-21 days.
