If you have an envelope this big, you don’t need to visit the Post Office to mail it. As long as you have access to a postage meter, or you have postage stamps, or you can print postage online from companies such as Stamps.com.
Read on to learn more about the cost of mailing a 9×12 envelope, how many stamps it requires, and the factors that affect the mailing cost.
How Much Does It Cost to Mail a 9×12 Envelope?
To calculate the cost of mailing a 9×12 envelope, you have to consider its weight and not just its envelope size. The price starts at $1.00. This will increase by $0.21 for every ounce that you add to the envelope.
The USPS considers the 9×12 envelope as a large envelope. You don’t have to visit the Post Office to mail such kind of envelope as long as you have access to a postage meter or can print postage online from a website such as Stamps.com. You can also stick postage stamps if you already know how many stamps are required.
In a 9×12 envelope, the first ounce requires two Forever Stamps. This is the equivalent of $1.00. Also, you have to pay extra if the envelope’s weight plus its contents exceed one ounce. For each additional ounce, you have to pay $0.21.
Actual Cost Depends On Several Factors
If the envelope’s contents are just a few sheets of paper, the envelope will have a uniform thickness. It will be bendable as well. The price will most likely be just the minimum, which is $1.00. It seems that you can have a maximum weight of 13 ounces that you can put inside this envelope size. Just multiply the number of additional ounces by $0.21 to get the total cost.
The envelope’s destination does not influence the cost as long as it is First Class Mail and its weight is no more than 13 ounces. If the 9×12 envelope is not lumpy and not inflexible, it is considered First Class Flat.
Aside from the weight, other factors will influence the cost of a particular 9×12 envelope. Here are some of these factors:
1. The Envelope Is Lumpy and Inflexible
If the envelope is inflexible and lumpy, it will be classified as First Class Package. Postage for this type of mail is $3.50 with a maximum weight of 4 ounces. The following table will show you the cost of 9×12 envelope postage if the envelope’s weight exceeds 4 ounces.

2. The Envelope Is Hard but Light
If the envelope is stiff but still light, the Post Office may require more Forever stamps. Envelopes could be stiff if they contain Styrofoam filler. They will be considered as a First Class parcel. Most likely, this kind of envelope will need five Forever stamps.
Forever stamps are so-called because you can use them forever. Ordinarily, they are non-denominated, or they don’t have value on their face. The word forever is written on the stamp with a diagonal strikethrough. Currently, they are worth $0.50.
3. Thickness of the Envelope
If the 9×12 envelope is thick, the cost of postage will increase. If it is about 1/4 inch thick, the envelope is still considered ‘flat.’ But if the thickness of the envelope approaches 3/4 inch, or if there are more than 1/4 inch variations in the envelope’s thickness, it will be considered a parcel. The envelope’s postage will be $4.10.
4. The Envelope Is Not Fully Flat
If the envelope is not completely flat, you will likely pay more for postage. The additional cost is that postal workers need to sort these kinds of mail by hand instead of just running them through postal machines.
Postal machines automatically sort flat envelopes. This makes the process easier and faster, and not too many hands are needed. But inflexible and lumpy envelopes have to be manually sorted. This process adds more labor and time to the sorting out process. That is why non-flat envelopes need more postage.
5. Size and Shape Affect Postage Cost
There are different postage costs for different types of mails. The different types of mails include letters, postcards, large flat envelopes, and parcels. Generally, the bigger the mail, the higher is its postage fee.
When it comes to First Class mails, postage for letters is higher than postage for postcards. Large flat envelopes need more postage stamps than letters. The highest of the bunch is parcel mails or boxes because of their processing and delivery costs.
9×12 Mail Is Classified as a Large Envelope
As per the USPS, a 9×12 envelope is a large envelope. This term is also known as flat mail. It is a classification given to envelopes that are more than 6 1/8 inches high, 11 1/2 inches wide, and 1/4 inch thick.
Most of these envelopes are used for mailing legal correspondence, product catalogs, and marketing newsletters. Some people are also using this size envelope to mail magazines, documents, reports, manuscripts, CDs, and even books. But to be considered ‘flat mail,’ the thickness of the envelope must be uniform.
These envelopes are oftentimes used to mail unfolded documents in sheets of 8 1/2“x 11” bond paper. The thickness of the envelope must not exceed 1/4 inch. Its height should not be more than 12 inches, and its width not more than 15 inches. The total weight of the envelope, including its contents, must not exceed 13 ounces.
If the envelope exceeds any of these flat mail parameters, the USPS will consider it a package. The postage rate that it will be subjected to is the parcel prices. Note that they will charge you $0.21 per ounce of additional weight.
What Are the Things You Need to Send an Envelope?
In sending large envelopes, you don’t need to visit the Post Office. But you need to have access to any of these three things:
- Postage meter,
- Postage stamps, or
- Online printing of postage from companies like Stamps.com.
If you have access to any of these three, you only need to address your envelope, attach the correct amount of postage on the envelope’s upper right corner, and hand it to your local mail carrier or drop it in the nearest post office collection box. Your recipient will receive your envelope within 3 working days.

How Many Stamps Are Required for a 9×12 Envelope?
The 9×12 envelope is the standard large envelope accepted by the USPS. Like a standard letter, this envelope requires postage stamps affixed at the top right corner to be provided proper postal service.
You can affix two First Class stamps to mail your 9×12 envelope if its total weight does not exceed 1 ounce. The USPS requires $1.00 worth of postage for this size’s envelopes that weigh no more than 1 ounce.
One First Class stamp has a value of $0.55. But you are only required to pay $1.00 if your 9×12 envelope does not weigh more than 1 ounce. The explanation for this is that you are paying the extra $0.10 for its convenience.
If your 9×12 envelope contains things that make it heavier than 1 ounce, the postage will be more than $1.00. Say your envelope weighs 4 ounces. That is 3 ounces more than the minimum. So, you will add three more stamps. At $0.55 per stamp, that will be $1.65. Add that to the $1.00 minimum price, and the total postage is $2.65.
