Rule of thumb for plus ones

I'm giving everyone a plus one who is over 18, except two grandmothers because they're traveling with the rest of their sides of the family.

People in relationships (no matter how long) should be invited with their significant other by name (not "plus one" or "and guest"). Ideally, everyone would be given the option of bringing a date, but it's not necessary, especially if single people will know a lot of other people there. People who are truly single should be given a plus one if they don't know a lot of other people. Everyone in your bridal party should be allowed a date, whether or not they're single.

We have budgeted to give everyone a plus one option regardless of relationship status.

To start with, plus ones and significant others are different.

For any guests who have a significant other at the time invitations go out, the invitation goes out addressed to both of them. i.e. Mary Smith and John Doe

A plus one is giving the option to someone who is truly single to bring a date or friend. That invitation would be addressed as Mary Smith and Guest.

It's nice to give people the option of a plus one, but not necessary. Some people only give plus ones to people who would be travelling or won't know anyone else at the wedding.

If you're inviting coworkers, yes, you need to also invite their spouses and significant others.

My fiance has a lot of single guy friends which I've seen bring another guy as their "date". That's why I was hesitant since it's not really a date...and they already know a lot of people at the wedding. My budget will go way up if I were to include their date. We're already at 300 people. And yes, I totally understand inviting our coworkers' spouses and significant others.

Do single co-workers get a plus one?

If you give one single person a plus one, you should give every single person a plus one.

Every adult gets a plus one. No if ands or buts about it.

Think back to when you were single. Would you have wanted to go a wedding without a plus one?

Everything Rebecca said (per usual).

Official boyfriends and girlfriends are not plus ones, they are significant others and should be invited by name. Truly single people do not HAVE to have a plus one (especially if they are familiar with a group of other guests) but it's a nice gesture if you have the room. If they will not know anyone at the wedding except the bride and groom, a plus one should be offered.

A plus one is given to truly single people to bring a guest of their choice. Which can be a friend. You don't get any say in who it is. It's nice to give to everyone single if you can but you don't have to, and you don't have to give to all singles or none. You should give them to people that are travelling long distances and would otherwise be alone or won't know lots of others at the event.

Anyone in a relationship gets their SO invited by name at the time invites go out. This is not a plus one because you invite the person by name.

I didn't give out any plus ones. That being said, all of the people we invited were invited with their SOs as a named guest even if we didn't know the SO. We also didn't have anybody who was single on our guest list.... which is weird but all of our friends are either married or in a serious relationship.

Alright ladies not a clear consensus but I'm appreciating all the responses.

Thank you all for the responses! This really helps me a lot.

From what I've read so far.... anyone in relationships will need to be invited by name. Single people gets a plus one if they don't know many people at the wedding. Everyone in the bridal party gets a plus one if they are single. Their SO are invited, obviously. Coworkers' significant others needs to be invited.
