Wedding Invitation Stamps: 2-Ounce Requirements

Wedding invitations are often heavier than standard letters, with many couples choosing to print their invites on heavier paper. As a result, you may need to use a two-ounce stamp to ensure your invitations are delivered. The weight of your wedding invitation will depend on several factors, including the thickness of the paper, the number of cards, and any embellishments included, such as a wax seal or ribbon. If your invitation weighs between 1.1 and 2 ounces, you will need a two-ounce stamp. You can purchase these stamps online or at your local post office. It is recommended that you take a sample invitation to the post office to be weighed to ensure you are using the correct postage.

Wedding invitations weighing over 1 ounce

Wedding invitations are often printed on heavier paper (80-110lb paper weight) and weigh more than standard paper found in typical letters. The weight of your wedding invitation will depend on several factors, such as the thickness of the paper, the number of cards, the use of a pocket-fold, and any embellishments included, such as ribbons or wax seals. These additional elements can quickly increase the weight of your invitation, pushing it over the 1-ounce limit and requiring additional postage.

If your wedding invitation weighs more than 1 ounce but less than 2 ounces, you will need a 2-ounce stamp. You can purchase these stamps online or at your local post office. The current price of a 2-ounce stamp is $1.01 each. Alternatively, you can use two 1-ounce forever stamps on your envelope instead of a single 2-ounce stamp. This option may offer more design choices to coordinate with your invitations, but it will cost slightly more in postage.

To ensure you have the correct postage for your wedding invitations, it is recommended to take a fully assembled invitation to your local post office. They can weigh your invitation and test it through a thickness template to determine the exact postage required. This will help you avoid any issues with your invitations not being delivered due to insufficient postage.

Invitations with non-standard shapes

When it comes to wedding invitations, weight, size, and thickness matter. The postage required depends on these factors. Basic wedding invitation suites (mailing envelope, flat-single-layer invitation, RSVP card, and RSVP envelope) can be mailed using a regular First-Class Stamp. However, if your invitation weighs more than one ounce, you will need additional postage.

Square envelopes are considered irregular by the USPS and will require additional postage. They will cost about $0.20 extra per invitation for the first ounce. Other non-standard shapes may also require additional postage, especially if they do not fit through the sorting machine and require hand sorting.

If your wedding invitation is more than 1/4" thick, embellishments such as ribbons, twine, or wax seals can push it over the threshold, requiring additional postage.

To avoid any issues, it is recommended to take a full wedding invitation to your local post office to have them weigh and measure it, providing an accurate estimate of the postage required.

Invitations with thickness over 1/4

If your wedding invitation is thicker than 1/4", it will not be able to go through the sorting machine and will need to be hand-sorted, which will result in additional costs. A ribbon tie for the envelope liner, for example, will usually make the envelope thicker than 1/4" and require additional postage.

The USPS considers letters with any of the following characteristics as non-machineable:

• Envelopes that are too rigid
• Envelopes that don't bend easily
• Envelopes that have clasps, strings, or other non-standard closures

In such cases, you will need to add a non-machineable surcharge to the base rate of postage. For example, in 2024, the rate for a non-machinable 2-oz letter was $1.47, including the $0.46 surcharge.

To avoid any issues, it is recommended that you take a fully assembled invitation to your local post office to have it weighed and inspected. They will be able to tell you exactly how much postage you need to buy and whether your invitation meets the criteria for non-machineable mail.

Using multiple 1-ounce stamps

Wedding invitations are often printed on heavier paper than standard letters and may include multiple enclosure cards, ribbons, or wax seals, all of which increase their weight. As a result, they frequently weigh more than one ounce and require additional postage.

If your wedding invitation weighs more than one ounce but less than two ounces, you have the option of using two 1-ounce forever stamps on your envelope instead of a single 2-ounce stamp. This is a perfectly valid option according to the USPS, and your invitations will be delivered without issue.

However, it is important to be mindful of the total weight of your invitations. Invitations weighing more than two ounces will require additional postage, such as a 3-ounce stamp. To ensure your invitations are delivered successfully, it is recommended to take a sample invitation, complete with all enclosures and embellishments, to your local post office for weighing and to confirm the correct amount of postage.

Buying 2-ounce stamps online

Wedding invitations are often printed on heavier paper than standard letters, and may include multiple enclosure cards, ribbons, twine, or wax seals, all of which can make them weigh more than a standard letter. If your invitation weighs more than one ounce but less than two ounces, you will need a two-ounce stamp.

The USPS offers a few different 2-ounce "forever" stamps, which will always be equal to the cost of mailing a 2-ounce first-class letter, even if the price increases. In 2024, the price of a two-ounce stamp from the post office is $1.01 each.

You can buy two-ounce stamps online from Amazon or eBay. Amazon offers faster delivery but at a higher cost, while eBay sells postage stamps at the same price as your local post office.
