A list and B list for wedding guests: how to do it kindly

Is a B list rude? The short answer

A B list is not rude in itself, but it only works with a tight schedule and a B list made of people who will not compare invitations.

The idea is simple. Your venue holds fewer people than your full list, so you invite a first group and keep a second group in reserve. As the first “no” answers come back, you invite people from the reserve to fill those seats. Nobody is harmed by the structure. What hurts is being able to tell: an invitation that arrives weeks after everyone else’s, or a guest who learns that a friend received theirs much earlier.

So the real question is not whether a B list is acceptable. It is whether your list, your calendar, and your circles of friends let you run one without anyone seeing the seams. If you cannot answer yes to that, a smaller list is kinder than a clumsy second wave.

Nothing here is about ranking people’s worth. An A list is the group you cannot picture the day without, and a B list is the group you would love to have if there is room. That is a capacity decision, and you never have to share it with anyone.

Who belongs on the A list and who on the B list

Your A list is the people the day would feel wrong without, and your B list is the people you want to invite but can live without if the room fills up.

Start with the people nobody questions: your immediate family, your closest friends, the wedding party, and anyone who would be genuinely hurt not to be there. Then look at everyone else and ask which of them would still be happy to receive an invitation in the second wave, and which would feel the date.

• Keep households together. Everyone who lives at one address goes in the same wave. Splitting a household makes the late invitation obvious at the very first mailbox.
• Keep couples together. If one partner is on the A list, the other goes there too. A plus-one follows the person they are coming with.
• Keep a friend group in one wave. If five college friends see each other weekly, invite all five in the same wave, or none of them. Mixed groups are the number one way a B list gets noticed.
• Put relatives with the family wave. A cousin who learns the rest of the family got a save-the-date months ago will feel it, even if no one says so.
• Choose B guests who live in different circles. A coworker who does not know your college friends, a neighbor, a parent’s friend from another city: these people will rarely compare.
• Do not put anyone on the B list who would be crushed to learn it. If the thought makes you wince, they belong on the A list or off the list.

Our guide on making the guest list covers how to get from a long list to a short one in the first place. A B list is what you build after that cut, not instead of it.

In MyWedding Planner, the guest list is organized by household, with a category for each guest (family, friends, and so on) and an age group (adult, teen, child, baby). That makes the household and friend-group logic above easy to check: you can see who lives together and which circle each guest belongs to before you decide on the waves.

Timing: first wave, second wave, and the latest B invitation

The first wave should go out early and carry an RSVP deadline short enough that the second wave can still go out with plenty of time to reply.

Work backward from your wedding date. Your caterer and venue have a date for the final headcount (check your contract for it), and your RSVP deadline sits well before that. Everything else hangs from the RSVP deadline: the earlier your first wave’s answers are due, the longer the runway for the second wave.

The schedule below is a working plan, not a rule. Adjust the weeks to your venue and to how far your guests travel. Out-of-town guests need more notice, so a B list works best for local guests who can say yes in a few days.

1. Send the first wave early. Mail it with a clear reply date, and say when the RSVP deadline is on the invitation itself.
2. Set a short RSVP deadline for wave one. The tighter it is, the sooner you know how many seats are free. Our guide on what to do when guests don’t RSVP covers the people who do not answer.
3. Call or message the quiet households yourself. The app does not send anything to guests, so you chase the missing replies. A kind “we’re finalizing numbers this week, can you let us know?” is enough.
4. Send the second wave within days of the first deadline. The shorter the gap, the less it looks like an afterthought.
5. Give the second wave its own reply date. Two weeks is a comfortable window for a local guest; shorter works if you phone first.
6. Set a last call for the final few seats. After this date, there is no third wave. Decide it now and hold to it.

The table at the end of this page turns those steps into a schedule you fill in, with each date expressed relative to the wedding.

What to avoid: invitations that look late and groups that compare

Two things give a B list away: a second-wave invitation that arrives much later than the first, and A and B guests in the same circle of friends.

Most of the other risks are variations on those two. A save-the-date that went to some people and not others is the same problem as a late invitation, one step earlier. If you send save-the-dates, send them to the A list only if you are sure the B list will not hear about it, or skip them for everyone.

• A wedding website already full of answers. If a B guest opens your site and sees that dozens of replies are in, the timing is visible. Think about what the page shows before you send a second wave.
• Social media. A friend who posts that they were invited months ago can undo everything. You cannot control it, which is a reason to keep friend groups in a single wave.
• A wave that is too small to hide. Inviting one coworker out of a team of six in the second wave is the same as announcing it. Invite the whole team or none of it.
• Telling people they are “on the list.” Promising a maybe gives someone a reason to wait and then be disappointed. If they ask, say you are still finalizing numbers.
• Letting the B list grow. A reserve list of five to ten people is manageable. A reserve of fifty means you invited a different, larger wedding.

If your honest answer to “will these people compare?” is yes, the problem is not the timing. The structure of the list is the issue, and the next section on alternatives is a better route.

Counting declines: how many seats will the first wave free?

No universal percentage of “no” answers exists, so estimate it from your own first-wave list and then replace the guess with real replies.

The popular claim that a fixed share of invited guests will decline does not trace back to a study we could find. How many seats come free depends on how far people travel, what the wedding costs them, and whether the date falls on a holiday weekend. Our guide on what share of guests decline shows how to estimate it group by group.

For a B list, the practical move is to build a cautious, a likely, and a hopeful count for your first wave. If even the cautious count fills the room, you will never reach your B list, and you may not need one. If the hopeful count leaves a dozen seats open, you know how deep the reserve needs to go.

As each reply arrives, enter it on your list. In MyWedding Planner, you can enter a reply that reached you by phone or text, and you can see who has not answered yet, which is exactly the list of households to nudge before you open the second wave. Guests can also reply online once your wedding website is published, which is included in the one-time payment of €69; the free trial needs no card.

Should we have a B list? Five questions to answer first

You should have a B list only if you can answer yes to all five questions below.

1. Is your A list alone small enough to fill the room if everyone says yes? If not, you are not running a B list, you are overbooking.
2. Can your B guests say yes within a couple of weeks, without flights or hotels to arrange?
3. Are your B guests in different circles from your A guests, so they will not compare invitations?
4. Is the date of your last B invitation already written down, and does it fall well before your caterer’s headcount deadline?
5. Would you be comfortable if a B guest found out? If the answer is no, the guest probably belongs on the A list or off the list.

Alternatives to a B list: a smaller list or a party-only invitation

If a B list feels risky, you can shrink the A list to fit the room or invite some people to part of the day only.

A single, smaller list is the cleanest answer. Everyone receives their invitation at the same time and nobody wonders where they ranked. The cost is a harder set of cuts up front, and our guide on making the guest list is built for that conversation.

Another option is a partial invitation: some guests come to the ceremony and cocktail hour, others to the dinner and dancing. In MyWedding Planner, each guest is invited to specific key moments only, such as the ceremony, the cocktail hour, the dinner, or the day-after brunch, so the guest list shows who is coming to what. That can ease a tight dinner count. It only works if the people who get the shorter invitation will take it as a warm welcome and not a demotion, so be honest about whether that fits your family.

A third route is a bigger room, or a smaller wedding with a casual get-together afterward for everyone else. It is a different event, but it may protect friendships better than a second wave that gets noticed.

Plus-ones deserve their own decision, since they take seats too. Our guide on seating plus-ones covers how to handle them once the list is final.
