Can i mail 4 ounces in regular envelope

According to the United States Postal Service (USPS), a regular letter-sized envelope can hold up to 3.5 ounces of weight. This is because the USPS has specific weight limits for each type of mailpiece, and a regular letter-sized envelope is considered a "letter" for the purpose of weight calculations.

If you need to mail something that weighs 4 ounces, you have a few options:

  1. Use a larger envelope: You can use a larger envelope, such as a "flat" or "large envelope," which can hold more weight. These envelopes are typically larger than standard letter-sized envelopes and are designed to hold heavier items.
  2. Use a different type of mailpiece: If you're mailing a small, lightweight item, you might be able to use a different type of mailpiece, such as a "package" or "parcel," which has a higher weight limit.
  3. Use a shipping service: If you need to mail something that weighs more than 3.5 ounces, you might need to use a shipping service like UPS or FedEx, which has different weight limits and pricing structures.

Here are the USPS weight limits for different types of mailpieces:

Keep in mind that these are general guidelines, and the USPS may have specific requirements for certain types of mailpieces or packages. It's always a good idea to check with your local post office or the USPS website for more information on weight limits and mailpiece requirements.
