placecard question

So does every guest get their own placecard, or do married couples only get one placecard with both names on it? Or can we do everyone who brings a date with both names on one placecard? I'm confused and I can't find the answer anywhere! TIA!

edited for grammar

This is what I have seen, as well as what we are doing

Married: Mr & Mrs. XXX or first names XXX

Couples (not married) both 1st and last names

We do not have any +1's but if we did it and did not know the name it would be Mr or Ms. XXX & guest.

Singles with no one: Mr. or Ms. 1st and last name

It depends on if you mean 'place cards' or 'escort cards'.

Escort cards are the cards we usually see at weddings that tell you what table you are sitting at. Place cards are at each table setting; therefore, your guests are assigned a table and a seat at that table. Typically, just escort cards are used.

It depends on how formal your wedding is. We did:

Mr. & Mrs. Joe Smith for married couples

Mr. Joe Smith and Ms. Jane Doe for non-married couples and for guests that brought a +1

Mr. Joe Smith and Guest we only had to do for 2 cards b/c we didn't know their +1's name

Some people just use first and last names and no Mr. or Ms./Mrs...it's up to you.
