Your save-the-date can take any size or form. If you decide on mailing cards out, then your cards can be the size of a postcard, or even smaller. Make sure the size does not cramp the wordings together.
The sole purpose of save-the-date cards is to give the people you intend to invite to your wedding plenty of advance notice. If, for example, you are planning to marry during the holiday season or a holiday weekend, you’ll want your guests to reserve you wedding date on their calendars months in advance. If you will be inviting guest from out of town who will need to fly in for the wedding, they will need time to make the necessary travel arrangements.
Rules & Etiquette – Again, few rules apply. The only information you must include is your names and wedding date, although I suggest including location information as well so wedding guests can begin their travel plans. Aim to send save-the-date cards soon after you secure your date and venue, or about 4-6 months prior to your wedding. Remember, everyone who receives a save-the-date also receives an invitation, so have your guest list finalized prior to sending them. You can, however, always add guests later (there is no rule that says everyone must receive a save-the-date card). Although formal replies are not required, you can get preliminary attendance estimates through word-of-mouth.
What To Include – When designing save the date cards, keep in mind that the only information that should be included are the date and the location. Travel and area information can also be included. This can be directions from the local airport, recommended resorts or hotels, useful phone numbers, and information on any group booking plans that have been made available. If you are using an online wedding planner, website, or some other online service, you may include that link as an additional courtesy to your guests. At the bottom, be sure to include the words.
What Not To Include – Save the date cards should not be used to provide detailed information about the event itself. This is not the time or place to discuss the rehearsal dinner, the reception, or the ceremony. It is inappropriate to include registry information as well. Guests who are interested in registry information can contact you themselves, or they can wait until the actual wedding invitations are sent out. Response requests are also not included. These notices are merely a courtesy ’heads up’ to your long distance guests and others who may require, for personal, professional, or medical reasons, some advance notice.
