How wedding invitation postage works in 2025
USPS increased First-Class rates on July 13, 2025. Here’s the quick math for wedding invitation postage 2025:
- 1 oz machinable letter: $0.78
- Each extra ounce: + $0.29 (so 1.2 oz costs $1.07, 1.9 oz is still $1.07, and 2.1 oz climbs to $1.36)
- Non-machinable surcharge: + $0.49 for square, rigid, or wax-sealed envelopes
- Postcard stamp: $0.61 for a standard 4 × 6 in RSVP card

Weight sets your base price, and shape can add forty-nine cents. A one-ounce rectangular invite needs one Forever stamp ($0.78). The same invite in a square envelope costs $1.27.
These figures apply nationwide through at least early 2026. Always weigh one fully assembled sample before you order stamps; even an eighth of an ounce can shift you to the next tier. Keep three numbers in mind: $0.78, $1.07, and $0.49, and you’ll get the postage right almost every time.
What most couples send
Most invitation suites fit one of three envelope profiles. Match yours to the closest option and the right wedding invitation postage 2025 rate becomes clear.
1.Classic A7, light
A 5 × 7 in invite plus reply card on standard cardstock weighs about 1 oz (≈ 28 g). One Forever stamp covers the $0.78 machinable rate.
2.A7, slightly heavier
Add a details card, map, or thicker wrap and weight often lands between 1.2 oz and 1.5 oz (34–43 g). That moves you to the two-ounce tier: $1.07 with either one 2 oz stamp or a Forever and an Additional Ounce stamp (+ $0.29), according to USPS Notice 123.
3.Square or wax-sealed
Even at 1 oz, the shape or texture triggers the non-machinable surcharge (+ $0.49). Total cost: $1.27. If weight also exceeds 1 oz, budget $1.56 (2 oz rate plus surcharge)
RSVP strategy matters. A reply envelope needs its own Forever stamp, while a 4 × 6 in postcard only requires the $0.61 postcard stamp, saving about 17 cents per guest.
Weigh one fully stuffed invitation on a kitchen or post-office scale before you buy stamps. Knowing which of these three buckets you’re in prevents last-minute postage runs.
Light & flat (1-ounce machinable)
If your finished invite weighs 1 oz (≈ 28 g) or less, stays rectangular, and skips bulky seals, one Forever stamp ($0.78) covers the letter rate. Most A7 envelopes with a single reply card fit this bracket; one stamp keeps the front clean and machinable.
Place a complete sample on a kitchen scale before you stamp. Even a slim vellum wrap can push weight above 1 oz, moving your wedding invitation postage 2025 cost to the next tier.
Heavier but machinable (over 1 oz up to 2 oz)
If your stuffed invite weighs more than 1 oz but no more than 2 oz (≈ 29–56 g) and the envelope stays rectangular, you move to the two-ounce tier. The cost is $1.07 for one 2 oz stamp (USPS price change). Prefer two stamps? Pair a Forever stamp ($0.78) with an Additional Ounce stamp ($0.29) for the same total.
You’ll usually hit this class after adding a reception card, directions, or thicker stock. Don’t assume “just a bit heavier” still travels for $0.78. Weigh a fully assembled invite at home or the post office; anything above 1.0 oz triggers the higher rate in the wedding invitation postage 2025 chart.
Awkward shape or texture (non-machinable)
Square envelopes, rigid cardstock, ribbon ties, or raised wax seals require hand sorting. USPS adds a $0.49 non-machinable surcharge to whichever weight tier applies.
- 1 oz square invite: $0.78 + $0.49 = $1.27
- 1.3 oz square invite: $1.07 + $0.49 = $1.56
Requesting hand-canceling protects delicate envelopes but does not cancel the fee.
Need a workaround? Place the square card inside a standard rectangular outer envelope. The outer stays machinable, so you pay only the letter rate shown in the wedding invitation postage 2025 chart, while guests still enjoy the square design inside.

Roll vs sheet: picking the format that fits
When you budget for wedding invitation postage 2025, start by counting how many stamps you need. One roll holds 100 Forever stamps; a pane (sheet) holds 20.
Mailing 60 invites plus thank-you cards? One roll covers the lot and leaves extras for holidays. At face value a 2025 Flag roll costs $78 ($0.78 each), but discount sellers such as Forever Postal offer the same roll for $76, saving about two cents per stamp.
Sheets trade volume for style. A “Love” floral sheet is $15.60 for 20 stamps on the USPS store, the same $0.78 each. Reaching 100 stamps means buying five sheets, so a roll usually wins on cost unless design matters more than price.
Design can still sway you. Many couples choose one decorative sheet for outer envelopes and a budget roll for RSVP and thank-you mail. You get personality up front while keeping overall spending low.If design matters more than price—and you’re considering a greener or more digital-friendly route—check out our comprehensive WhatsApp Wedding Invitation Guide for creative, low-cost alternatives.

How many stamps to buy (calculator + rules of thumb)
Two missteps can drain both time and budget: buying for every guest instead of every household, and skipping a safety buffer.
1.Count addresses, not guests. One hundred guests usually equal about 60 mailing addresses—a 40 percent drop right away.
2.Add a 10 percent cushion. Misprints and last-minute changes happen; a small overage prevents midnight post-office runs. Wedding planners such as The Knot recommend the same buffer for printed materials.
3.Match RSVP stamps one-for-one. Use a $0.61 postcard stamp for a 4 × 6 in RSVP card or a full Forever stamp for a reply envelope.
Our on-page calculator handles the math for you. Enter (a) invitation count, (b) postage tier, and (c) RSVP type, and it returns totals plus the built-in 10 percent extra. It also converts those totals into rolls or sheets. For example, 60 invites in the 2 oz tier with postcard RSVPs require one roll of Forever stamps and three sheets of 2 oz “Wedding Blooms.”
Remember the two golden ratios that simplify wedding invitation postage 2025 planning: addresses = invitations and extras = 10 percent. Follow them and you’ll avoid last-minute stamp runs.
Common mailing gotchas (avoid delays and surprises)
The Postal Service follows rules, not good intentions. Run these four checks before you stamp anything:
1.Weigh a finished sample. Include every insert, belly band, and envelope. A quick visit to the post-office scale—or a ten-dollar kitchen scale—can save more than its cost.
2.Respect the non-machinable fee. Square, rigid, or wax-sealed envelopes always pay the $0.49 surcharge, according to the USPS Domestic Mail Manual. Hand-canceling protects ink but never waives the fee.
3.Move wax seals inside. Place the seal on an inner envelope, then slip that into a standard outer shell. The mailing envelope stays machinable while guests still enjoy the reveal.
4.Stay within letter specs. Oversize or extra-thick pieces are priced as Flats, starting at $1.63 for the first ounce—an easy budget hit.
Keep these checks in mind and you’ll protect both timelines and wallet while navigating wedding invitation postage 2025 requirements.
Conclusion
Wedding invitation postage may feel like a small detail, but it carries outsized importance. A few cents or an overlooked surcharge can derail your timeline, bounce envelopes back, or stretch your budget more than you’d expect. By weighing one full sample, matching your suite to the right USPS tier, and ordering stamps with a small buffer, you’ll set yourself up for smooth mailing day success.
Think of your stamp choices as both functional and expressive. A clean roll of Forever stamps gets the job done at the lowest cost, while specialty “Love” or floral sheets add a meaningful design flourish that guests notice before they even open the envelope. And if you’re working with heavier or more creative stationery—like wax seals or square envelopes—simply plan ahead for the surcharge rather than fight it.
Ultimately, getting wedding invitation postage right means balancing accuracy, aesthetics, and savings. Five extra minutes of prep and a little price comparison can save you last-minute stress, unexpected costs, and even forty or fifty dollars across your mailing list. With the right approach, you’ll not only send your invitations confidently but also create a first impression that sets the tone for your celebration.
