Choosing The Perfect Stamp Size For Wedding Invites

Wedding invitations are an important part of wedding planning. The type and amount of stamps you include on an envelope could make or break your stationery arriving safely. The size, aspect ratio, weight, thickness, and destination of your envelope will determine the type and number of stamps you need. In the US, the United States Postal Service (USPS) is the ultimate authority on sending wedding invitations. The USPS offers a number of wedding-themed stamps for one-ounce and two-ounce letters. The current cost of a first-class 1-ounce forever stamp is $0.73, while a 2-ounce stamp is $1.01. To avoid the dreaded return to sender, it's best to consult a post office professional directly on what is required to successfully send out your invite.

Weight, size, and thickness matter

When it comes to wedding invitations, weight, size, and thickness matter—a lot. These factors will determine how much postage you'll need, and whether your invites will make it to their destination without a hitch. Here's a breakdown of what you need to know:

Weight

The weight of your wedding invitation will significantly impact the postage cost. Most standard letters weighing up to one ounce will only require a single Forever Stamp, which currently costs around $0.73. However, wedding invitations often include multiple pieces, such as RSVP cards and envelopes, details cards, and other embellishments, which can quickly add to the overall weight. For invitations weighing between one and two ounces, you'll need additional postage, such as a 20-cent stamp on top of the Forever Stamp.

Size

The size and shape of your wedding invitation also play a crucial role in determining postage costs. Rectangular envelopes that fall within specific dimensions (at least 5 inches long and 3.5 inches wide, but no larger than 11.5 inches long and 6.125 inches high) are generally considered standard and will incur the basic postage rate. However, if you opt for a square or non-rectangular shape, you may be subject to additional costs. Square invitations, for example, typically require a $0.70 stamp regardless of weight because they cannot be processed through the sorting machine and must be hand-cancelled, which means they are manually sorted and stamped.

Thickness

The thickness of your wedding invitation is another critical factor. Envelopes that exceed a thickness of 0.25 inches are considered non-machinable and will incur a surcharge. This typically applies to invitations with three-dimensional details such as wax seals, ribbons, or belly bands. If you're using a ribbon to tie your envelope liner, consider the thickness of the knot, as it may push your envelope into the non-machinable category. Additionally, rigid or bulky invitations made from thicker cardstock or non-paper materials like wood or acrylic will also require extra postage.

To ensure you use the correct amount of postage for your wedding invitations, it's highly recommended to assemble a complete invitation suite and take it to your local post office for weighing and measurement. They will be able to advise you on the exact postage required, and you can avoid the embarrassment of having your invitations returned or your guests being asked to pay the remaining postage.

Forever stamps

Wedding Forever Stamps are wedding-themed versions of the standard Forever Stamp. They are a great choice for wedding invitations as they have no expiration or denomination and will cover the cost of first-class postage forever, even if the cost of postage goes up. Forever Stamps are valid for 1-ounce wedding mailings, but some wedding invitations may require 2-ounce stamps.

The number of Forever Stamps you will need for your wedding invitations depends on the weight and dimensions of your fully stuffed envelope. If your invitations are standard size and weigh under one ounce, you will only need one Forever Stamp to cover the mailing cost. If your envelope is heavier or has additional embellishments, you may need to purchase additional postage stamps in smaller denominations to use alongside your Forever Stamp.

• Take a fully assembled and ready-to-mail invitation to your local post office to have it weighed and inspected. This will help you determine the correct amount of postage needed and avoid any issues with your invitations being returned due to insufficient postage.
• Consider the weight, shape, and size of your invitations when budgeting for postage. Non-standard sizes and shapes, such as square envelopes, may require additional postage and hand-cancelling.
• If you are sending save-the-dates or RSVP cards, remember to include the correct postage for these as well. Postcard stamps are a cost-effective option for these, but they can only be used for rectangular cards that are no bigger than the standard size.
• If you want to add embellishments to your invitations, such as ribbons or wax seals, keep in mind that these may increase the weight and thickness of your envelopes, requiring additional postage.
• If you are short on time or want to avoid shipping costs, buying stamps at your local post office is a good option. However, it is recommended to call ahead to ensure they have the type and quantity of stamps you need.

Non-standard shapes

When it comes to wedding invitations, there are a few things to consider to ensure that your carefully crafted missives reach their intended recipients. The shape, weight, thickness, and size of your invitations will determine the cost of postage and whether they can be processed by the postal service without additional fees.

Square-shaped wedding invitations are considered irregular by postal services and will require additional postage. These envelopes will cost about $0.20 extra per invitation for the first ounce. Other non-standard shapes may also incur additional costs, so it is important to check with your local postal service provider.

If your wedding invitation is thicker than 1/4" (a quarter of an inch), it may also require extra postage. Embellishments such as ribbons, twine, or wax seals can quickly add bulk to your envelope, pushing it over the weight and thickness limits for standard postage rates.

To avoid any unexpected costs or delays, it is recommended that you take a fully assembled invitation to your local post office to have it weighed and assessed for thickness. They can advise you on the correct postage required and any additional services that may be needed, such as hand-cancelling, which adds a classic look to your envelope but will cost extra.

Vintage stamps

Sourcing Vintage Stamps

Finding vintage stamps for your wedding invitations can be a fun treasure hunt. You can explore online marketplaces such as Etsy, where shops like Treasure Fox offer a wide variety of unused vintage stamps. These stamps are a great option as they are new and can be purchased in bulk, ensuring a cohesive look for your invitations. Additionally, you can connect with specialised businesses like Little Postage House and Flourish Fine Writing, which curate custom postage sets for invitations, offering a personalised touch to your stationery.

Planning and Timing

When incorporating vintage stamps, it is crucial to plan ahead and allow for extra time. Sourcing vintage stamps may take longer than buying standard stamps, and you may need to order them in bulk or work with a specialist to curate the perfect set. Additionally, consider visiting your local post office to weigh your assembled invitation and confirm the correct postage required. This will ensure that your invitations arrive safely and on time to your guests.

In conclusion, vintage stamps can elevate the look and feel of your wedding invitations. With careful planning, attention to detail, and a bit of creativity, you can incorporate vintage stamps to add a touch of elegance and uniqueness to your special day.

Buying stamps

When it comes to buying stamps for your wedding invitations, there are a few things to keep in mind. Firstly, the cost of postage will depend on the weight, size, and thickness of your invitations. Most wedding invitations are 5" x 7" as this size typically only requires a "forever" stamp, which costs around $0.55. If your invitations are larger or heavier, you may need additional postage. For example, if your invitation has multiple pieces and weighs between one and two ounces, you'll need a $0.70 stamp. Square invitations, regardless of weight, will also require a $0.70 stamp as they cannot be processed through the sorting machine and must be hand-cancelled.

It's important to note that any envelope thicker than 0.25 inches will also require additional postage. This is often the case when invitations include a ribbon tie or wax seal. To avoid unexpected costs, it's recommended that you take a fully assembled invitation to your local post office to be weighed and inspected. They will be able to tell you exactly how much postage you need and can advise on any non-machinable surcharges that may apply.

When it comes to buying stamps, you have a few options. The most obvious and economical choice is the United States Postal Service (USPS). They offer a variety of themes and colors, including a "Love/Wedding" subcategory. If you're looking for vintage or unique stamps, Etsy is a great option. You can also find state stamps here, which can add a personal touch to your postage. Amazon is another good resource, especially for stamps that have been recently retired.

When designing your invitations, it's important to keep postage in mind. To use a single stamp, your invitation must be between 3.5" x 5" and 6.125" x 11.5" and no thicker than 0.25 inches. It should also weigh less than one ounce. If your invitation exceeds these dimensions, you will need to use multiple stamps to cover the cost of postage.
