How many invited wedding guests actually come?

Most couples should expect about 75 to 85 percent of invited guests to come to a local wedding, and closer to 55 to 65 percent for a destination wedding. The rate varies by who is on the list, so estimate each group of guests separately rather than applying one number to everyone.

The figure most planners start from is a 20 percent decline rate. The Knot's senior editor calls it a rule of thumb that many wedding professionals agree on, in The Knot's guide to how many guests RSVP no, and adds that it moves with the time of year and the distance guests travel. The useful work is in that adjustment.

Why one rate doesn't fit the whole list

A guest list is several smaller lists stacked together, and each one behaves differently. Your sister is coming. Your partner's university friend who now lives in Singapore may not. Averaging them hides the number you need, which is how many chairs, plates, and hotel rooms the day will use.

The groups below are the ones that move the total most. The ranges are the rules of thumb planners work from, not a promise, and your own family's habits count for more than any average.

Attendance by guest group

Immediate family and the wedding party: 95 to 100 percent

Parents, siblings, grandparents who can travel, and everyone standing up with you. Count them all, and treat any decline here as a surprise rather than a statistic.

Close friends and family nearby: 85 to 95 percent

People within a couple of hours' drive whom you see often. They come, unless the date clashes with something fixed.

Guests who have to fly: 60 to 75 percent

Distance is the single biggest factor in declines. A flight adds cost, time off work, and a hotel, and some guests will decide the trip is too much even when they love you. Holiday weekends and peak season push this lower.

Colleagues, parents' friends, and distant relatives: 50 to 70 percent

The outer ring of any list. Many will send a gift and a kind note instead. Invite them because you want them there, not to make up the numbers.

Families with young children: lower than you think

If the wedding is adults only, parents need a sitter, and those traveling need one for the weekend. Expect more declines from this group, and give them as much notice as you can. The wording that helps is in how to word an adults-only wedding invitation.

What else moves the number

Beyond who is on the list, a few details of the day shift the rate up or down for everyone.

• The day of the week. A Friday or Sunday wedding costs guests a day off or a late night, and a weekday one more so. Expect a few points fewer than a Saturday.
• Holidays. A long weekend helps travelers who have the time and hurts those with family plans of their own. December weddings compete with every other gathering of the month.
• Notice. A date announced a year out gives guests time to save and book. One announced in three months loses the people whose calendars were already full.
• Cost to attend. A long weekend of events, a dress code that means buying something, or a remote venue with expensive rooms all add up, and some guests decline on price alone.

A worked example

Here is a local wedding with a fair share of out-of-town friends, 160 invited guests in all.

• 24 immediate family and wedding party, at 95 percent: 23
• 60 close friends and family nearby, at 85 percent: 51
• 50 guests who have to fly, at 65 percent: 33
• 26 colleagues and parents' friends, at 60 percent: 16

That comes to about 123 guests, or 77 percent of the list. The same 160 people estimated at a flat 80 percent would give 128, close enough here. Shift the list toward travelers and the gap widens fast, which is why the group-by-group version is worth the five minutes.

Turning the estimate into a plan

For the venue

Choose a room that holds the high end of your range, ideally everyone invited. Lists heavy with local family tend to beat the average, and a venue that is too small is the one problem you can't fix in the last month.

For the budget

Price the expected number, then check you could afford the high one. Catering, drinks, and rentals scale per head, so ten extra yeses are a real line on the budget. The approach is set out in how to set a wedding budget.

For the caterer

The final count comes from replies, not estimates. Set your RSVP deadline a week or two before the caterer needs the number, so there is time to chase the quiet households. The timing and the follow-up script are in how to set an RSVP deadline.

How to raise the yes rate

Some declines are fixed: a clash, a cost, a due date. Others come from guests who couldn't plan in time. You can reduce the second kind.

• Send save-the-dates early, especially for travelers. The countdown is in when to send save the dates and invitations.
• Publish travel details before the invitation, including a hotel block, so guests can price the trip.
• Make replying easy. A short card or a link that takes a minute returns more answers than one with six questions. Wording is in RSVP wording that gets replies.
• For a destination wedding, give guests a year and keep their costs in view. That planning is covered in how to plan a destination wedding guests can afford.

Running a B-list

A second list only works with time built in. Send the first wave about eight weeks out with a deadline four weeks later, and release the second wave as declines arrive. If the second invitations go out three weeks before the wedding, the guests receiving them will know why.

Keep the B-list short and ordered, so you are not deciding under pressure. The tiering that makes it work is in how to organize a wedding guest list.

Common questions

An estimate gets you to the right venue; the replies get you to the right count. With Simplyweds, households reply on an online RSVP, and every yes, no, and silence lands on the same guest list.
