Set your RSVP deadline three to four weeks before the wedding, roughly a week before your caterer's final count is due. That gap is not padding — it is the week you will spend chasing the twenty percent of guests who have not replied, because there are always twenty percent.
The deadline, and the week after it
Work backwards: your caterer needs a final number two to three weeks out, so the RSVP date sits a week before that. Print the deadline on the card and on your website.
Then expect to chase. Roughly a fifth of guests do not reply by any deadline, and it is not personal. Plan a round of texts and calls for the week after, and split the list between you so you are contacting people you actually know.
Online, paper, or both
An online RSVP on your wedding website is faster, cheaper, and gives you a live count with meal choices attached. A paper card with a stamped return envelope gets better response rates from older guests. Offering both is normal and costs little.
Whichever you use, the form should name the invited guests and not allow adding names. Most plus-one and children awkwardness is an RSVP design problem rather than an etiquette one.
Collect the right things
Attendance, meal choice if you need it, and dietary requirements or allergies. Nothing else. Long RSVP forms lower response rates.
Keep dietary requirements in one list with names attached - your caterer needs named plates, not a count of vegetarians, and the seating chart is how the kitchen finds them on the night.
What to actually do about it
- Set the RSVP date a week before the caterer's deadline
- That week is for chasing, and you will need it.
- Use a form that cannot add guests
- It should list the invited names and allow only yes or no. This removes the most common source of headcount drift.
- Give your caterer named dietary requirements
- Not a count. They need to know which seat the nut allergy is in, which means the seating chart and the allergy list have to match.
- Confirm when your final number locks
- That is the number you pay for, whether or not those guests come. Know the date and what a late change costs.
Common questions
When should the wedding RSVP deadline be?
Three to four weeks before the wedding - about a week before your caterer's final count is due. That week is for chasing the roughly twenty percent of guests who do not reply by any deadline.
What do you do when guests don't RSVP?
Chase them directly by text or phone in the week after the deadline, splitting the list so each of you contacts people you know. It is entirely normal and not personal; plan for it rather than being surprised.
Should wedding RSVPs be online or on paper?
Online is faster and gives a live count with meal choices; paper gets better response rates from older guests. Offering both is normal. Either way, the form should name the invited guests and not allow adding names.
