TL;DR: Mail wedding invitations 6–8 weeks before the wedding (8–12 weeks for destination), address each envelope to the specific people invited by full name and title, and let the host line, formality of wording, and RSVP details do the work of setting expectations. Etiquette exists to prevent confusion — not to impress anyone.

Direct answer

Wedding invitation etiquette comes down to four decisions, in this order:

1. Who is hosting — this determines the host line at the top of the invitation.
2. How formal the wedding is — this sets the wording, paper, and titles you use.
3. Who is invited — every guest's name goes on the outer envelope. No "and Guest" unless you genuinely mean any guest.
4. What guests need to know — date, time, place, dress code, and how to RSVP.

Get those four right and the rest is style.

Practical sections

Timing: when to send what

• Save-the-dates: 6–8 months before a local wedding, 8–12 months for destination or peak-season weekends.
• Invitations: mail 6–8 weeks before the wedding date. Add 2–4 weeks for destination weddings or guests traveling internationally.
• RSVP deadline: 3–4 weeks before the wedding, which gives you 1–2 weeks to chase non-responders before your caterer's final headcount is due.
• Thank-you notes: within 3 months of the wedding (within 2 weeks for gifts received before the wedding).

The host line

The host line tells guests who is paying for and welcoming them to the wedding. Match it to reality:

• Bride's parents hosting: "Mr. and Mrs. John Smith request the honor of your presence…"
• Both sets of parents hosting: list the bride's parents first, then the groom's.
• Couple hosting themselves: "Together with their families, [Name] and [Name] invite you…"
• Divorced parents: put each parent on a separate line, no "and" between them.
• Deceased parent: you can honor them in the wording ("daughter of [Name] and the late [Name]") but they are not listed as a host.

Wording by formality

• Very formal / black tie: "request the honour of your presence" (British spelling, traditionally for ceremonies in a house of worship), full names with titles, time spelled out ("half after five o'clock").
• Formal: "request the pleasure of your company," full names, no nicknames.
• Semi-formal: "invite you to celebrate," first and last names, conversational tone.
• Casual: first names only, plain-language wording, no honorifics required.

Addressing the envelope

Outer envelopes are formal; inner envelopes (if used) can be slightly more familiar.

• Married couple, same last name: "Mr. and Mrs. John Smith" (traditional) or "Mr. John Smith and Mrs. Jane Smith" (modern).
• Married couple, different last names: "Ms. Jane Doe and Mr. John Smith" — alphabetical or whichever you know better first.
• Unmarried couple living together: both names on one line, alphabetical.
• Children invited: list them by name on the inner envelope, under their parents' names. If kids' names are not on the envelope, they are not invited.
• A guest can bring a date: add "and Guest" only when you do not know the partner's name. If you know their partner's name, use it.

Plus-ones, kids, and dress code

• Plus-ones are owed to anyone married, engaged, or in a long-term relationship. Beyond that, it is your call — just be consistent across friend groups.
• No-kids weddings: never write "no children" on the invitation. Address envelopes to adults only and add a line to your wedding website. Tell parents directly if needed.
• Dress code belongs in the lower right corner of the invitation or on the reception card: Black Tie, Black Tie Optional, Cocktail Attire, Semi-Formal, Garden Party, Casual.

Registry and money

Do not print registry information on the invitation itself — it reads as a request for gifts. Put it on your wedding website and let parents and the wedding party share the link by word of mouth.

RSVP mechanics

• Pre-address and pre-stamp the response card.
• Number the back of each RSVP card lightly in pencil keyed to your guest list — about 10–15% of cards come back without a name filled in.
• Offer a clear deadline ("kindly reply by [date]"). Online RSVPs are fully acceptable for any formality level today.

FAQ

When should wedding invitations be mailed?

Mail invitations 6–8 weeks before the wedding for local guests, and 8–12 weeks before for destination weddings or weddings with significant international travel. Save-the-dates should go out 6–8 months earlier so guests can book travel.

Whose names go on the host line?

The host line names whoever is financially hosting and formally welcoming guests. Traditionally that was the bride's parents, but today it is common to list both sets of parents, the couple themselves, or "Together with their families" when contributions are mixed. Match the wording to what is actually true.

Is it rude to put the registry on the invitation?

Yes — listing the registry on the invitation itself is considered impolite because it implies guests are expected to bring a gift. Put registry information on your wedding website instead, and rely on parents and the wedding party to share it when asked.

How do I tell guests it's an adults-only wedding?

Address the envelopes only to the adults invited and do not write children's names on the inner envelope. Add a line on your wedding website such as "We love your kids, but this is an adults-only celebration." For close family, follow up with a personal call so they have time to arrange childcare.

Do I have to give every single guest a plus-one?

No. Etiquette requires plus-ones for anyone married, engaged, or in a serious long-term relationship, and for members of the wedding party. Beyond that, it is your decision, but apply the rule consistently — do not give plus-ones to one friend group and not another.

What dress code wording should I use?

Use a recognized standard: Black Tie, Black Tie Optional, Formal, Cocktail Attire, Semi-Formal, Dressy Casual, or Casual. Place it in the lower right corner of the invitation or on the reception card. If your dress code is unusual (garden party, all-white, beach formal), define it briefly on your wedding website.

How long should I give guests to RSVP?

Set the RSVP deadline 3–4 weeks before the wedding. That gives you 1–2 weeks to call non-responders — expect to chase 15–25% of your list — and still hit your caterer's final headcount deadline, which is typically 7–10 days before the event.
