When it comes to sending mail, choosing the right type of envelope or package can make a significant difference. The U.S. Postal Service (USPS) provides various options, one of which is a large envelope, also known as a “flat.” But how big is a large envelope USPS? Let’s dive into the details to find out.
A large envelope, or “flat,” in USPS terms must have one dimension that is greater than 6-1/8 inches high, 11-1/2 inches long, or 1/4 inch thick. However, it should not exceed 12 inches in height, 15 inches in length, or 3/4 inch in thickness. The maximum weight for a large First-Class Mail envelope is 13 ounces. If the envelope exceeds these dimensions or weight, it will be considered a package.
Defining a Large Envelope
In USPS terms, a large envelope must have one dimension that is greater than 6-1/8 inches high, 11-1/2 inches long, or 1/4 inch thick. However, it should not exceed 12 inches in height, 15 inches in length, or 3/4 inch in thickness. These dimensions are what differentiate large envelopes from standard letters and packages.
Comparing Large Envelopes with Standard Letters and Packages
Standard letters have a maximum height of 6-1/8 inches and a maximum length of 11-1/2 inches. On the other hand, packages have a minimum height of 3 inches and a minimum length of 6 inches. Packages also have a maximum combined length and girth of 108 inches (or 130 inches for USPS Retail Ground and Parcel Select), a far cry from the maximum dimensions of a large envelope.
In essence, large envelopes fall between standard letters and packages in terms of size. They are ideal for mailing items like newsletters, magazines, and unfolded sheets of paper.
Weight Restrictions for Large Envelopes
The maximum weight for a large First-Class Mail envelope is 13 ounces. If your envelope exceeds these dimensions or weight, it will be considered a package and subject to parcel prices, which are generally higher.
Addressing and Sealing Large Envelopes
When preparing your large envelope for mailing, ensure that you write the delivery and return addresses on the same side of your envelope. The addresses should be written parallel to the longest side. The envelope must also be made of paper with a minimum 50 pounds paper basis weight and be sealed properly.
Postage Rates for Large Envelopes
As of July 9, 2023, postage rates for large envelopes start at $1.35 for the first ounce. For each additional ounce, the cost is $0.24. These rates apply to First-Class Mail service, the most commonly used service for large envelopes.
Prohibited Items in Large Envelopes
USPS has certain restrictions on what can be sent within a large envelope. Some domestically prohibited items include airbags, ammunition, explosives, gasoline, liquid mercury, and marijuana (medical or otherwise). Some domestically restricted items, which can be sent under certain conditions, include aerosols, cigarettes and tobacco products, cremated remains, hand sanitizers, live animals, and lithium batteries.
Understanding the dimensions, weight restrictions, and postage rates for large envelopes can help you choose the most cost-effective and efficient mailing option. By adhering to USPS guidelines, you can ensure your large envelope is categorized correctly and not treated as a package, saving you from potential additional costs.
