Wedding stationery etiquette is not a list of rules. It is a sequence of decisions, each one shaping the next. Get the host line right and the name order follows. Get the envelope addressing right and the plus-one question is answered before a single conversation needs to happen.
This guide walks through each decision in the order you actually face it. Where Australian and American conventions differ, both are named.
The six decisions, in order
- Who is hosting? Sets the opening line of the card.
- Whose names appear, and in what order? Determines how the couple is introduced.
- How are envelopes addressed? Establishes who is invited before the card is opened.
- How are children communicated as not invited? Controls headcount without a blunt statement.
- Who gets a plus one, and how is that shown? Manages guest count expectations before the RSVP returns.
- What belongs on the main card, and what goes on a details card? Decides what each piece of the suite carries.
Whichever version you land on, it needs to be set properly. Every design here is editable before you order.
Who Is Hosting?
The host line is the first line of the invitation. It names whoever is organizing and funding the event. In both the US and Australia, the principle is the same: if you are paying, your name appears.
One set of parents hosting
If only one family is contributing, only that family appears. A non-contributing parent does not appear in the host line simply because they are a parent. In both the US and Australia, formal tradition opens with courtesy titles for the hosting parents.
Both families hosting
When both families share costs, both sets of parents appear, or the couple uses the grouped form: “Together with their families” followed by the couple’s names. This is now the standard in both markets when couples want to acknowledge both sides without listing four names in sequence.
The couple hosting themselves
When the couple funds the wedding, the card opens with their names directly. This is the dominant format for self-funded weddings across both markets.
When a parent has died
This is where US and Australian practice diverges most clearly. US convention generally omits the deceased parent from the host line to avoid asymmetry, and honors them elsewhere: the ceremony program, a note in the suite, or a line beneath the couple’s names such as “daughter of Jane Smith and the late Robert Smith.”
Australian practice more often includes the late parent by name in the host line itself:
“The late Margaret Harper and Mr. Thomas Harper request the honor of your presence…”
Or, for the couple hosting:
“In memory of the late Margaret Harper, Sophie Harper and William Whitmore invite you…”
Neither approach is wrong. The question is whether the couple wants the invitation to carry the memorial, or whether they prefer to reserve that for the ceremony.
Divorced and remarried parents
If both divorced parents are contributing and both need to appear, each goes on a separate line. Stepparents appear beside their own spouse only, not beside the ex-spouse. When parents use different surnames, US guidance defaults to alphabetical order by surname.
Australian practice uses the same structure. In practice, many Australian couples find the grouped “together with their families” form sidesteps the complexity entirely, and Australian guests accept it as equivalent without reading it as evasion.
For wording templates covering each of these scenarios, see wedding invitation wording at Paperlust, which covers the formal, casual, and every family-configuration variant.
Whose Names Appear, and in What Order?
After the host line, the couple’s names appear.
The US traditional default places the bride’s name first. Australian practice follows the same default in formal contexts but treats name order as more flexible, with alphabetical by first name also widely accepted without objection.
For same-sex couples in both markets, alphabetical by first name is the standard default.
When the couple writes the host line themselves, the order is their preference. The one constraint: if the host line refers to “their daughter Emma,” Emma’s name must lead in the body of the invitation as well.
For how these conventions translate into wording, the wedding invitation wording examples at Paperlust shows the same-sex, couple-hosted, and parent-hosted formats side by side.
Addressing Envelopes: Titles and Conventions
The envelope is where guest eligibility is established before the card is opened. These are the current conventions in both markets.
Courtesy titles
Mr., Mrs., Ms., and Dr. are standard in the US and Australia. Mx. (gender-neutral) is accepted in both countries and carries more official weight in Australia, where it appears on government identity documents.
In US formal usage, “Miss” applies to unmarried women under 18. “Ms.” covers all other women regardless of marital status, and is the safe default when the person’s preference is unknown. Australian practice is similar, though “Miss” for younger unmarried women still appears in formal correspondence.
When both partners hold the same professional title, “Drs. Sophie and William Chen” is the US convention. In Australia, “Dr. Sophie White and Dr. William Chen” on separate lines is more natural.
Who appears on the envelope
Married couple at one address: “Mr. and Mrs. William Chen,” or if the wife uses her own surname: “Ms. Sophie White and Mr. William Chen.”
Unmarried couple at one address: each name on its own line, alphabetical by surname, each with their own title.
Inner and outer envelopes
Inner and outer envelopes are an American formal tradition: the outer carries the formal mailing address, the inner names exactly who is invited. In Australia, single-envelope addressing is the norm outside formal religious ceremonies.
An adults only line sits on the details card, where it reads as information rather than a rebuke.
How to Signal That Children Are Not Invited
This is the question couples ask most often and find hardest to answer. The short answer: addressing is the primary signal, and for most guests it works without a single word on the card.
The naming method
Address the envelope to adults only. “Mr. and Mrs. David Smith” means two seats. “Mr. and Mrs. David Smith, James and Lily” means four. Guests who have received formal invitations before read the names on the envelope as the complete guest list.
The limitation: not every guest has received a formal suite before and may not read it this way.
The pre-filled RSVP
This technique originated in the US and is now widely used in Australia: pre-fill the RSVP card with the number of seats allocated.
“We have reserved 2 seats in your honor.”
The guest fills in their dietary requirements and attendance without a field to add extra names. This is the most efficient mechanism for controlling headcount without any awkward follow-up call.
The details card note
If a written statement is wanted, a line on the details card is the right placement:
“We respectfully request an adults-only celebration.”
In the US, etiquette guidance generally reserves this wording for an insert rather than the main card. In Australia, a brief line at the base of the main invitation is also accepted without issue.
What to avoid in both markets: “No children” or anything that reads as an announcement rather than a request. A quiet line is read; a prominent one is debated.
Who Gets a Plus One?
The plus-one decision is a headcount and budget decision first. Etiquette tells you how to communicate what you have decided, not who must receive one.
Common practice in both markets
Married guests, registered partners, and guests in long-term relationships are the standard recipients. For single guests and newer couples, a plus one is discretionary.
One common exception in both countries: a guest who will know very few people at the wedding is often extended a plus one regardless of relationship status, as a courtesy.
Showing it on the envelope
Named partner: “Ms. Rachel Johnson and Mr. Daniel Ortiz” Unnamed plus one: “Ms. Rachel Johnson and Guest” No plus one: “Ms. Rachel Johnson” with no addition
If the partner’s name is known, naming them is more courteous and reduces ambiguity. “And Guest” is correct; it is also slightly impersonal, and guests notice.
The RSVP control
The pre-filled seat count handles the plus-one question as well. A guest without a plus one receives a card showing one seat. No conversation required.
What the Invitation Must State, and What Goes on a Details Card
A main invitation carries one thing: the event. That is the complete scope of the card.
Required on the main card, in both markets
- Host line
- Names of the couple
- Date (day and full date; spelled out for formal invitations in both countries)
- Ceremony start time
- Venue name and city; full address if the venue is not widely known
- RSVP deadline and contact method, or a direction to the enclosed RSVP card
What belongs on a details card or the wedding website
In both US and Australian etiquette, the following are placed on an insert, a details card, or the couple’s website. They do not belong on the main invitation card.
- Registry information or gift preferences (in both markets, putting this on the main card is considered a significant breach)
- Accommodation recommendations and hotel room block codes
- Travel directions
- Dress code (US exception: black-tie or black-tie optional appears at the lower right of the main card; in Australia, dress code is almost always on a details card)
- Wedding website URL (in the US, sometimes included at the bottom of the main card; in Australia, more commonly placed on the details card or RSVP card)
The distinction exists because the main invitation is a keepsake. People keep invitations for years. A hotel block code is useless after the wedding date. Keeping the card clean of temporary details respects both the design and the reader.
For couples exploring suite options, the wedding invitation designs at Paperlust show multi-piece suites alongside single-card formats, which helps clarify how many inserts a design comfortably accommodates. Addressing is where this shows most, and calligraphy wedding invitations set an expectation about the envelope that a printed label will not meet.
Invitation designs with wording you can edit line by line before printing. The $5 sample pack puts seven designs and an envelope in your hands, including real foil and letterpress, so you judge paper and finish off a screen.
Frequently Asked Questions
Can I write “no children” on the wedding invitation?
Etiquette guidance in both the US and Australia recommends against it on the main card. Address the envelope to adults only, pre-fill the RSVP with the seat count, and if you want a written statement, place it on a details card. The message lands without the phrasing becoming the thing guests discuss at the table.
How do I include a deceased parent in the host line?
US convention typically omits a deceased parent from the host line and recognizes them in the ceremony program or with a line beneath the couple’s names, such as “daughter of Jane Smith and the late Robert Smith.” Australian practice more commonly includes the late parent in the host line itself: “the late Margaret Harper and Mr. Thomas Harper…” Both approaches are accepted. The choice depends on whether the couple wants the invitation to carry the memorial.
Whose name goes first on the invitation?
Traditionally, the bride’s name comes first in both the US and Australia. For same-sex couples, alphabetical by first name is the standard default in both markets. When the couple writes the host line themselves, they choose the order they prefer. The one constraint is consistency: the name order must match any reference to the couple in the host line.
Do I have to offer a plus one to every guest?
No. Married and long-term partnered guests are the expected recipients in both markets. For single guests and newer relationships, a plus one is optional. Communicate the guest count through the envelope addressing and the pre-filled RSVP rather than through a separate conversation.
What belongs on a details card and not on the invitation?
Registry information, accommodation recommendations, travel directions, dress code (in most Australian and many US weddings), and the wedding website URL. None of these belong on the main invitation. They are practical and temporary; the main card is a keepsake.
Does Australian invitation etiquette differ from American?
Yes, in specific ways. Australia more readily accepts a short adults-only note on the main card; the US typically moves this to an insert. Inner and outer envelopes are an American tradition rarely used in Australian weddings outside formal religious ceremonies. Australian practice more often includes a deceased parent in the host line. Title conventions are otherwise similar, with Mx. having slightly more official recognition in Australia than in the US.
