Plus-One Etiquette: Who Gets a Plus-One?
Plus-one etiquette comes down to one rule: invite couples as a unit, so anyone who is married, engaged, or living with a partner gets that partner invited by name. Beyond that, a plus-one is a courtesy you choose to offer based on your budget and headcount, and the invitation itself should make the answer clear so no guest ever has to ask.
Below is who gets a plus-one, how the norms change by event type, copy-paste wording for including or declining guests, and how to handle the person who asks anyway.
Who Gets a Plus-One
Start with the people who should always be invited with a partner, then decide how far past that list your space and budget reach.
Always include
- Spouses, fiancés and live-in partners. Etiquette treats them as a social unit. Inviting one without the other reads as a snub, even at a small event.
- Long-term partners. A common rule of thumb is a relationship of a year or more, or anyone you have already met as a couple.
Include if you can
- Guests who won't know anyone else. A college friend at a family-heavy wedding has a much better night with a companion.
- Members of the wedding party or the hosting team. They give you hours of their time; a guest is a small thank-you.
- Out-of-town guests traveling alone. Someone flying in for your event is spending real money to be there.
Usually no plus-one
- New relationships of a few weeks or months, unless you know the partner.
- Coworkers invited to a personal event, when you're inviting several of them.
- Guests at a shower, a girls' or guys' night, or any event built around a specific friend group.
Whatever line you draw, apply it to everyone in the same category. If one single cousin gets a guest, all the single cousins do. Consistency is what makes a limit feel fair instead of personal.
Plus-One Etiquette by Event Type
Norms shift with the occasion. Use this table as a starting point, then adjust for your venue size and budget.
| Event | Typical norm | What decides it |
|---|---|---|
| Wedding | Partners of married, engaged and cohabiting guests; others at the couple's discretion | Per-head catering cost and venue capacity |
| Bridal or baby shower | No plus-ones | The guest list is the honoree's circle |
| Office holiday party | Company policy: employees only, or employee plus one | Budget per head; state it on the invite |
| Thanksgiving dinner | Family partners included; new partners by request | Chairs at the table and the size of the turkey |
| Kids' birthday party | One parent stays with younger kids; siblings by request | Venue per-child pricing |
| Restaurant birthday dinner | Named guests only | The reservation count |
| Open house or holiday drop-in | "Bring someone" is fine if you say so | Room to mingle and food quantity |
For weddings in particular, see how an example wedding RSVP page handles named guests and party size on one form.
Plus-One Wording on the Invitation
The envelope, text, or event page is where guests learn whether they can bring someone. Make it unmistakable.
When you know the partner's name
Write both names: Jordan Lee and Sam Ortiz. This is the most gracious option, and it saves you asking later for place cards or name tags.
When you don't know who they'll bring
Write the guest's name followed by and Guest: Jordan Lee and Guest. On a digital invite, add a line near the RSVP button:
We've saved two seats for you. Please add your guest's name when you reply.
When the invitation is for one person
Address it to the invited person only, and let the reply form reinforce it:
We have reserved one seat in your honor.
On a digital invitation, the form should do the enforcing so you don't have to. On RSVPlinks paid plans you can cap the group size per RSVP (1 for a solo invite, 2 when a plus-one is included) and add a custom question such as "Your guest's full name" so you have it for seating.
How to Say No Plus-Ones Politely
Say it once, on the invitation, in a calm sentence. Guests take a limit in stride when it's stated up front; they take it personally when they learn it from a follow-up text. Pick the line that fits your event:
- Space-based: "Due to limited space, we're able to include only the guests named on this invitation."
- Wedding: "We've kept our celebration small and can only accommodate those named on the invitation. Thank you for understanding."
- Dinner party: "We've set the table for [number], so this one is invited guests only."
- Office party: "This year's celebration is for team members only."
- Adults-only: "Our evening is adults-only and limited to invited guests."
Skip all caps, bold warnings, and "NO PLUS ONES." One polite sentence plus a form that only accepts one person carries the message without any scolding.
When a Guest Asks to Bring Someone
Answer within a day so they can plan. If the answer is no, keep it short and warm:
We'd love to include everyone, but we're keeping this one to [number] people, so we can't add guests. I really hope you can still come!
If you can say yes:
Of course! Send me their full name by [date] so I can add them to the list.
If someone RSVPs for two when you invited one, don't let it slide until the day of. Text them privately:
Quick note on your RSVP: we have one seat for you, since we're keeping numbers tight. So glad you're coming!
Then correct their party size in your guest list so the headcount stays accurate.
Plus-Ones and Your Headcount
Every plus-one you offer is a potential extra plate, chair, and drink. While planning, count each invitation with a guest as two people until the reply comes back. Ten single guests offered a plus-one can add up to ten seats, which matters a lot at a 40-person venue.
Timing matters too, especially this season:
- Thanksgiving (Thursday, November 26): ask for plus-one names by Sunday, November 15, so you can size the turkey (a common rule of thumb is 1 to 1.5 pounds per person) and add chairs. An example Thanksgiving dinner RSVP page shows how to collect adults and kids in one reply.
- Office holiday parties (roughly December 1–20): settle the partner policy before invitations go out, since it can nearly double the catering count. A company event RSVP page lets employees answer for themselves and a guest in one step.
- Weddings: decide who gets a guest before you print or send anything. Adding plus-ones later is awkward, and taking them away is worse.
Once replies start arriving, keep attendees and their guests on one list instead of a spreadsheet you rebuild every week. Here's how to track RSVPs without a spreadsheet.
Plus-One Etiquette for Guests
If you're on the receiving end, the rules are simple:
- Bring a guest only if the invitation says so, by name or with "and Guest."
- Include your guest's full name in your RSVP.
- Don't ask for a plus-one to a small dinner or a shower.
- If your plans change, update your reply so the host isn't holding an empty seat.
- Introduce your guest to the hosts early in the event.
Frequently Asked Questions
Do you have to give a plus-one to someone in a relationship?
You should invite a guest's spouse, fiancé, or live-in partner, and it's customary to include long-term partners too. For newer relationships, a plus-one is optional. Whatever rule you choose, apply it to all guests in the same situation.
Is it rude to not allow plus-ones?
No, as long as you still invite established couples together and state the limit clearly on the invitation. Most guests understand that venues and budgets have limits. What feels rude is inconsistency, such as one friend getting a guest while another in the same situation doesn't.
How do you write "and guest" on an invitation?
Write the invited person's full name followed by "and Guest," for example "Jordan Lee and Guest." If you know the partner's name, use it instead. On a digital RSVP form, allow a party size of two and ask for the guest's name.
How long should a couple be dating to get a plus-one?
A common rule of thumb is about a year, or long enough that you've met the partner. Engaged and cohabiting couples always count as a unit, however long they've been together.
Should a plus-one bring a gift?
Usually not a separate one. At a wedding or birthday, a couple typically gives one gift together, and the invited guest takes the lead on it.
