How to set a wedding RSVP deadline from your caterer's final-count date, what etiquette guides recommend, and how to word the reply-by date on invitations.
Set your RSVP deadline about ten days before your caterer needs final numbers. For most weddings that lands two to four weeks before the day. The Emily Post Institute suggests a reply-by date "usually two to three weeks before the wedding", which works when your caterer's deadline is close to the wedding, and needs moving earlier when it isn't.
The RSVP deadline exists for one reason: so you can give accurate numbers to the people who need them. The earliest of those is almost always the caterer, and some venues and rental companies want counts too. Ask each of them for their final-count date before you print a single invitation.
Then work backwards. Late replies are normal, and chasing them takes about a week: a friendly reminder two days after the deadline, a firmer one at five days, a phone call at seven. That week has to fit between your RSVP deadline and the caterer's date, plus a couple of days to build the seating chart and send meal choices by table.
| Caterer needs numbers | Set the RSVP deadline | Weeks before the wedding |
|---|---|---|
| 1 week before | 3 weeks before | 3 |
| 2 weeks before | 24 days before | About 3½ |
| 3 weeks before | 31 days before | About 4½ |
| 4 weeks before | 38 days before | About 5½ |
The calculator below does this with your own wedding date, and gives you every other invitation date too.
When to send save-the-dates, invitations and RSVP reminders
Too late and there is no time to chase non-responders before the caterer's deadline, so you either guess the numbers or pay for meals nobody eats.
Too early and guests who can't commit yet (waiting for time off, a babysitter, a flight price) either say no to be safe or don't reply at all. A deadline much more than a month before the wedding also sits closer to the invitation than to the day, which makes the gap feel artificial.
Guests also need time to answer. Invitations are usually mailed six to eight weeks before the wedding, so a deadline three to four weeks out gives everyone at least a month.
When most guests travel, send invitations earlier (eight to twelve weeks ahead) so they can book, and expect your venue or hotel room block to set its own earlier deadlines. Your RSVP deadline should come before any of those, even if that is well over a month before the wedding.
Keep it plain and specific, with the weekday if there's room:
Put the date on the response card or the RSVP page, not only on your wedding website. Guests read the thing they are holding.
Some guests will miss it. That's expected, not rude. The step-by-step plan and the exact messages to send are in what to do when wedding guests don't RSVP.
Usually two to four weeks. Pick the exact date by counting back about ten days from when your caterer needs final numbers.
No, not if your caterer needs final numbers two to three weeks before the wedding. Much earlier than that, guests who can't commit yet tend to say no or not reply at all.
It helps. Guests often deal with post and admin at the weekend, and a named day ("Saturday, May 22") is easier to remember than a date on its own.
