Wedding Save the Date: The Complete Guide to Timing, Wording, and Mailing

The save the date is the first physical thing your guests will hold from your wedding. It arrives months before the formal invitation, before most of your planning is done, and before anyone outside your immediate circle knows much about the day. That makes it more than a scheduling notice. It is the first impression of an event you have probably been thinking about for a long time.

And yet most save the date guides skip the one part that determines whether the piece actually lands well: what happens to the envelope. This guide covers everything from timing and wording to format choices, postage, and the envelope decisions that most wedding stationery designers never think about because they are not the ones doing the mailing.

What a save the date is and what it is not

A save the date announces your wedding date and general location. Its job is to give guests enough notice to hold the date, arrange travel if needed, and request time off work. That is genuinely all it needs to do.

It is not the invitation. It does not ask for an RSVP. It does not need ceremony times, a full venue address, dress code details, accommodation lists, or registry information. When couples try to include all of that, the save the date becomes confusing and guests sometimes assume it is the actual invitation and start wondering whether they need to respond.

The save the date says: mark your calendar, the wedding is happening, more details to come. The formal invitation, which arrives months later, provides every logistical detail guests need to actually attend.

Element	Save the date	Wedding invitation
When sent	6 to 12 months before	6 to 8 weeks before
RSVP included	No	Yes
Ceremony time	Not needed	Required
Full venue address	City and state only	Required
Dress code	Optional brief mention	On invite or insert card
Registry info	Never	On wedding website only

 

What to include on a save the date

What you must have:

Both names, as they will appear on the formal invitation. The wedding date written in full, day of week included: "Saturday, October 11, 2026" rather than "10/11/26." Numerals-only dates cause confusion, particularly for guests accustomed to day-month-year formatting. City and state where the wedding is taking place. The full venue address is not needed at this stage and can change anyway. A line that says "Formal invitation to follow" or just "Invitation to follow." This single phrase tells guests this is a preview, not the invitation, and that they do not need to respond right now. Without it, some guests genuinely wonder whether they have already received the invitation.

What adds real value:

Your wedding website URL. Even if the site is sparse when you send save the dates, include it. You can build it out over the following months and guests have somewhere to go for updates. An engagement photo, especially if the card design is built around the image. A short accommodation note for destination or multi-day celebrations: "Room block details at our website" is plenty. A general formality hint if your wedding is unusually formal or unusually casual, because that genuinely helps guests start planning.

What to leave off entirely:

Full venue address. RSVP instructions or cards. Registry information. Hotel details in full written out on the card. Ceremony or reception times. Anything that implies guests need to respond immediately.

When to send save the dates: the timeline that actually works

Sending too early means guests lose the card before it is relevant. Sending too late means conflicts already exist on calendars. Here is the timeline that accounts for different wedding scenarios.

Standard local wedding: Send 6 to 8 months before the date. This gives guests enough runway to check their schedules, request time off, and make basic plans without receiving the card so far in advance that it ends up in a drawer.

Summer or holiday weekend wedding: Send 8 to 10 months before. Summer weekends book up fast. A wedding on Labor Day, Memorial Day, or over Thanksgiving weekend competes with pre-existing family traditions and travel plans. Give guests extra lead time.

Domestic destination wedding: Send 9 to 12 months before. Guests need time to research flights, book accommodation, and accrue vacation days. 12 months out is not too early for a domestic destination.

International destination wedding: Send 12 to 18 months before. Passports, visa research, flight costs, and accumulated vacation time all require significant advance planning. Some guests may need to start saving specifically for the trip.

Short engagement: If your engagement is under six months, skip save the dates entirely and go directly to formal invitations sent 8 to 10 weeks before the wedding. They do the job of both pieces when the timeline is compressed.

Wedding type	Send save the date	Send formal invitation
Local, standard	6 to 8 months before	6 to 8 weeks before
Summer or holiday weekend	8 to 10 months before	6 to 8 weeks before
Domestic destination	9 to 12 months before	3 to 4 months before
International destination	12 to 18 months before	3 to 4 months before

One timing rule most guides mention but couples often overlook: do not send before your date and venue are confirmed. City and state is enough for the save the date, but the date itself must be locked in with your venue before anything goes to print. A save the date with a wrong date or a date that later changes is worse than sending nothing.

Who gets a save the date

One per household, not one per guest. A married couple at the same address gets one save the date. A family with children at the same address gets one. Two single friends at different addresses each get their own.

Only send save the dates to guests who are confirmed on your final wedding guest list. This matters more than most guides emphasize. Any guest who receives a save the date will expect a formal invitation to follow. If they do not receive one, they will know they were removed from the list. That conversation is difficult to have and almost impossible to explain gracefully. Do not send a save the date to anyone you are not completely certain will be invited to the wedding.

If you are still working through plus-one decisions when save the dates are being prepared, wait until those decisions are made before sending. Guests who are listed as confirmed plus-ones on the invitation but who never received a save the date will not feel slighted. Guests who received a save the date and never received an invitation will.

How many to order:
Count households, not individuals. Add 15 to 20 percent for addressing errors, late additions, and keepsake copies. A 150-guest list across roughly 100 households needs 115 to 120 save the dates. Order the buffer upfront. Running out of envelopes after you have already addressed 140 of them is a real problem.

Card, postcard, or magnet: how to actually choose

Most guides treat this as a design preference. It is more useful to think of it as a practical decision.

Card in an envelope

Printed on cardstock, mailed in an envelope. Most design flexibility, works with every paper stock and finish. The envelope itself creates a first impression before the card comes out. Cards in envelopes signal formality, which is why they are the right choice for traditional, black-tie, or formal weddings where the stationery suite is a considered design decision from the start.

Postage: First-Class letter rate, 78 cents for a standard one-ounce piece.

Postcard save the date

Printed on cardstock, mailed without an envelope. The design is visible as soon as the piece arrives in the mail pile. Lower cost per piece, no envelope needed, and qualifies for the USPS postcard rate of 61 cents if dimensions fall within the required range: 3.5 to 4.25 inches tall and 5 to 6 inches long. The most common postcard save the date size is 4 x 6 inches, which fits the postcard rate window cleanly.

Here is the one thing most guides miss: a postcard that exceeds the USPS maximum dimensions (over 4.25 inches tall or over 6 inches long) no longer qualifies for the postcard rate. A 5 x 7 inch card mailed without an envelope is not a postcard by USPS standards. It mails at First-Class letter or flat rate instead. The cost difference per piece is small but on 200 households it adds up. Confirm your exact dimensions with the printer before ordering.

Postcards work well for casual, destination, modern minimalist, and outdoor weddings. They are the most budget-efficient format for large guest lists. They are not the right choice for formal or black-tie weddings where the stationery is doing formality work.

Magnet save the date

Printed on magnetic backing, mailed in an envelope. Goes on the refrigerator and stays visible. The average fridge magnet stays up for 6 to 8 months, compared to a card or postcard that typically gets filed or set aside within weeks. For destination weddings or any event where the early planning window is long, the visibility advantage is real.

Cost per unit is higher than cards or postcards. Postage is also higher because the magnetic backing adds thickness and rigidity, which can trigger non-standard handling. Always take a fully assembled magnet envelope to a post office counter to confirm the exact postage before buying stamps for the full run.

Situation	Best format
Formal or black-tie wedding	Card in envelope
Large guest list, budget-conscious	Postcard
Destination or long lead-time wedding	Magnet
Modern, casual, or outdoor wedding	Postcard or card
Design flexibility and suite coordination	Card in envelope

What no save the date guide tells you about the envelope

This section covers what you actually need to know about mailing, not just designing.

The envelope is the first thing your guests see. When a save the date arrives in someone's mailbox, they pick up the envelope. They read the address, feel the weight, notice the color. That happens before the card comes out. A plain white envelope with a stick-on return address label sends one message. A colored envelope with a thoughtfully addressed face sends a different one. The card design you spent hours on is invisible until the envelope is opened.

The right size envelope for a 5 x 7 save the date card is an A7. An A7 envelope measures 5.25 x 7.25 inches and holds a 5 x 7 card with the correct 1/4 inch clearance in height and 1/8 inch clearance in width. Too tight and the card corners get damaged on insertion. Too loose and the card shifts in transit and arrives creased. See the full envelope size guide for every card-to-envelope pairing.

Square envelopes add 49 cents per piece in postage. Square envelopes have an aspect ratio of 1:1, which falls outside the USPS required range of 1.3 to 2.5. They are automatically classified as non-machinable and charged a 49-cent surcharge on every single piece, regardless of how light the card is. On 180 save the date envelopes, that is $88.20 in unexpected postage. If your designer has proposed a square envelope, factor that number into the decision before committing.

One Forever stamp (78 cents) usually covers a save the date card in an envelope but not always. A standard 5 x 7 card on regular cardstock in an A7 envelope typically comes in just under one ounce. Add a heavier cardstock, a magnet format, or any insert and you may be at or over one ounce, which needs $1.07 instead. Take one fully assembled, sealed envelope to a post office counter before buying stamps for the full run. Five minutes at the post office saves the hassle of 180 under-stamped pieces coming back.

Wax seals get crushed in automated sorting equipment. If wax seals are part of your envelope design, request hand-cancellation at the post office counter when you drop off the envelopes. This is free and completely standard. Without it, the envelopes go through automated sorting equipment and the wax seals arrive cracked. The same applies to any embellishment that adds bulk to the exterior of the envelope.

Self seal envelopes save more time than you expect on large runs. Sealing 180 A7 envelopes by gum flap activation means moistening and pressing 180 individual flaps under time pressure. Self seal envelopes with a peel-and-press adhesive strip seal on contact with no moisture. On a run of 180 envelopes, that time saving is real and the seal quality is more consistent because human moisture application varies.

Always include a return address. Undeliverable save the dates without a return address go to the USPS Mail Recovery Center in Atlanta rather than back to you. Pre-printed return addresses on custom printed envelopes look the most polished and eliminate the label step on every piece.

Addressing save the date envelopes: every scenario

How you address the outer envelope communicates care before the card is read. Here is every recipient type with the correct format.

Married couple, same surname:
Mr. and Mrs. James Anderson
1234 Oak Street, Columbus, Ohio 43201

Married couple, different surnames:
Ms. Rachel Torres and Mr. David Kim
(list alphabetically or by closer relationship to the couple)

Unmarried couple at the same address:
Ms. Sarah Lee
Mr. James Carter
(each name on its own line)

Single guest:
Ms. Emily Reyes

Single guest with named plus-one:
Ms. Emily Reyes and Mr. Daniel Moore

Single guest with unnamed plus-one:
Ms. Emily Reyes and Guest
(capital G on Guest is correct)

Family with children invited:
Mr. and Mrs. James Anderson and Family

Family where children are not invited:
Address only to the parents. Do not write "and Family." Addressing only the adults communicates an adults-only event without a separate awkward conversation later.

Doctor:
Dr. Sarah Bennett and Mr. Paul Bennett

One rule most guides mention but many people ignore: Send all save the dates at the same time rather than in waves. Guests talk to each other. If one cousin receives a save the date two weeks before another, the perception of being on a secondary list creates friction nobody needs. The only reasonable exception is international guests who may need to receive theirs slightly earlier due to longer postal delivery times.

What makes Business Envelopes different for save the date mailings

Business Envelopes has been supplying commercial envelopes to US businesses, event planners, and individuals since 1997. For wedding save the date mailings, here is what matters.

The right envelope sizes in the right formats. A7 and A6 envelopes in white, colored, and self seal configurations. All the sizes a save the date mailing needs from one catalog, with free ground shipping and same or next business day shipping on blank stock.

Colored envelopes that make the mailing noticed. Wove solid-color and starburst pattern formats. For save the dates where the outer envelope is part of the design intent, a colored envelope changes how the piece is received in a mail pile before the card is ever touched.

Self seal closures that make large runs manageable. Peel-and-press adhesive on all major commercial sizes. No moisture, consistent seal, noticeably faster on runs of 100 or more envelopes. Available across every size couples need for invitation mailings.

Custom printed envelopes with return address pre-printed. Eliminate the return address label step on every piece. PDF proof before production, 7 to 10 business day turnaround, artwork on file for reorders. The whole mailing looks considered and finished rather than assembled from separate parts.

No minimums, free shipping. Order exactly the quantity you need plus the buffer. Every order ships free to the contiguous 48 states. Blank stock ships same or next business day.

Frequently asked questions 

When should I send save the dates?
Six to eight months before the wedding for local events. Eight to ten months for summer or holiday weekend weddings. Nine to twelve months for domestic destination weddings. Twelve to eighteen months for international destination weddings.

What size envelope fits a 5 x 7 save the date card?
An A7 envelope (5.25 x 7.25 inches) is the correct match. See the full size guide for every card-to-envelope pairing.

Do postcard save the dates cost less to mail?
Only if the dimensions qualify for the USPS postcard rate: 3.5 to 4.25 inches tall and 5 to 6 inches long. Cards within that range mail at 61 cents. Oversized cards mailed without an envelope, like a popular 5 x 7 format, mail at First-Class letter rate instead. Confirm your exact dimensions with the printer before ordering.

How many save the dates should I order?
Count households, not individual guests. Add 15 to 20 percent for addressing errors, additions, and keepsakes. A 150-guest list across 100 households needs roughly 115 to 120 save the dates.

Do I send a save the date to everyone on the guest list?
Yes, and only to guests you are certain will be invited. Anyone who receives a save the date will expect a formal invitation to follow. Do not send one to anyone whose place on the guest list is not fully confirmed.

What happens if I use a square envelope?
Square envelopes are automatically non-machinable and charged a 49-cent surcharge per piece by USPS regardless of weight. On 150 envelopes that is $73.50 in extra postage. Rectangular A7 envelopes do not trigger the surcharge.

Can I use self seal envelopes for save the dates?
Yes, and for runs over 50 pieces they are significantly faster. Self seal envelopes seal on contact without moisture and produce a more consistent seal than gum flap activation done quickly under time pressure.

Where does the return address go?
Upper-left corner of the envelope face or centered on the back flap. Both are correct. Back flap is more traditional for formal stationery. Front upper-left is more practical for postal processing.
