When should wedding RSVPs be due? A timeline that works

Set the RSVP deadline four to six weeks before the wedding. That is the short answer, and it holds for most UK weddings. The longer answer is that the date has to sit between two other dates you do not fully control: the day the venue and caterer need final numbers, and the day the invitations land. Get those two right and the deadline picks itself.

Start from the venue's date, not the wedding date

Almost every venue and caterer asks for final numbers two to three weeks before the day. Some want the table plan at the same time. Ask them for the exact date and write it down. Your RSVP deadline needs to be at least two weeks before that, because:

• A chunk of guests will miss the deadline. One in five is normal; a quarter is not unusual.
• You need a week to chase them, and a few days for the stragglers to actually answer.
• The table plan takes an evening you will not want to spend the week of the wedding.

So if the venue wants numbers on 1 June, the RSVP deadline should be no later than 18 May, and 11 May is more comfortable.

The timeline, working backwards

Here is how it fits together for a wedding on Saturday 20 June.

For a wedding abroad, move everything a month earlier: save the dates at nine to twelve months, invitations at four to five, and the deadline at eight weeks, because guests are booking flights.

How long to give people

Guests need two to three weeks from receiving the invitation to a sensible deadline. Shorter than that and the ones who have to check with work or arrange childcare feel hurried. Longer and the invitation goes on the fridge and stops being seen.

That gives a rule of thumb: send invitations eight to ten weeks before the deadline, and set the deadline four to six weeks before the wedding. The invitation then lands twelve to sixteen weeks out, which is the three-to-four-month window most planners recommend.

If you are sending the invitation as a link rather than in the post, guests reply faster, usually within days, because the reply is one tap away rather than a card to find a stamp for. You can give a slightly shorter window and still get most replies in the first week.

Picking the actual day

A few small things make a measurable difference to how many people reply on time.

• Make it a weekday, ideally a Friday or a Monday. People sort admin at the start or end of the working week.
• Write it in full. "Friday 15 May 2027" removes the "is that this year?" moment for a long engagement.
• Avoid bank holidays and school holidays. Half term is the worst week of the year for replies.
• Give the reason. "We need to confirm numbers with the venue" turns a request into a favour people understand.

Different deadlines for different guests

You do not have to give everyone the same date. Two common splits:

• Day and evening guests. Evening guests have less to organise; their deadline can be two weeks later, which also spreads out the replies.
• Overseas guests. Give them an earlier deadline and send their invitations first; they need to book travel.

If you are using one guest list with tags for each group, keep the deadline in the wording of their invitation rather than trying to run two forms.

What to do on the day after the deadline

Expect to be missing a fifth of your replies. This is normal and not a comment on your friends. Give it the weekend, then on the Monday send one message to each household that has not replied. Keep it to two lines and include the link, because "I couldn't find the invitation" is the real reason for half of them. Our guide to chasing RSVPs politely has wording you can use.

Set yourself a private, final cut-off about ten days after the public deadline. Anyone still silent after that gets a short, kind message saying you have assumed they cannot make it, which almost always produces an answer within the hour.

If you are already late

Invitations went out late, or the deadline has passed and the replies have not come. The fix is the same: pick the latest date that still gives you a week before the venue needs numbers, tell every outstanding guest that date in one message, and make replying as easy as possible. A link they can tap gets answered on the bus; a card they have to find does not.

A note on "regrets only"

Some couples try to skip the deadline altogether by asking guests to reply only if they cannot come. It sounds efficient. In practice it means you cannot tell a yes from a guest who forgot to look at the invitation, and the caterer bill is based on a guess. Ask everyone to reply, give them a date, and make it easy. Our RSVP wording examples cover the line for the deadline itself.

If your invitation is a link, the deadline sits at the top of the reply form and every reply lands in your list as it is sent. RSVP Websites shows you who has replied and who has not, so the chase on the Monday after is a short list rather than a spreadsheet.
