Your save-the-dates have long been sent and a big box of beautiful wedding stationery just arrived at your front door. We know you're itching to start stuffing those perfectly calligraphed envelopes, but take a quick look at the calendar. Is this when you're supposed to send wedding invitations?

When to Send Wedding Invitations

Traditional wedding etiquette suggests mailing your invitations six to eight weeks before the Big Day. If you're throwing a destination wedding, though, that period can be pushed out to as early as twelve weeks prior. Although your Save-the-Date alerted guests to mark their calendars, this widow will still allow them time to schedule travel or take off from work. Additionally, it offers them ample time to send back your RSVP card before the deadline.

For overeager brides who are ahead of schedule, holding on to invitations that are ready a bit early may a challenge. The rest of us, though, may have trouble enough just trying to plan in advance for all of the pieces of the puzzle to come together. Even if you've picked out your paper styles on time, there are printing timelines, envelope stuffing, and calligrapher schedules to take into account. Who knew there'd be so many timetables to consider for piece of mail?

Timelines to Consider In Planning When to Mail Wedding Invitations:

Calligraphy: If you're using a calligrapher to address your envelopes, be sure to get in touch with him or her as soon as you've confirmed your invitation printing schedule. Calligraphers require anywhere from 2-3 weeks or more to address your envelopes, so you'll need to confirm dates and tack that onto your timeline.

Assembly: If you're sending out hundreds of envelopes, don't forget it may take you a few days to stuff and seal all of that stationery. Don't plan to be able to take your invitations straight to the post office as soon as you receive them.

Postage: When you have a fully assembled invitation to test, weigh it at the post office you plan to use for the mailing. If you've been eyeing a particular set of stamps, you'll need to ensure the envelope weight matches the postage you plan to use before placing stamps. Believe it or not, the weight can slightly vary from one post office to the next, to be sure to stick to just one location.
