You’ll usually want to send wedding invitations about 2–4 months before the big day, with destination weddings and peak‑season dates going out earlier so guests can plan.

Ideal send-out window

  • Many modern etiquette guides suggest mailing invitations around 8–12 weeks (2–3 months) before the wedding, so guests have time to RSVP, arrange travel, and buy outfits/gifts.
  • Some planners recommend a slightly longer window of 9–11 weeks to give you more cushion for mail delays and late replies.
  • If you’re also using save-the-dates, those typically go out 8–10 months beforehand, so the invitations themselves don’t need to be ultra-early.

Destination & special‑case weddings

  • For destination weddings , invitations commonly go out 3–4 months ahead so guests can book flights and hotels at reasonable prices.
  • If most guests will be traveling far or your date is on a holiday weekend, lean toward the longer end of the range (around 4 months) to avoid schedule conflicts.
  • Very small, informal weddings where everyone is local can sometimes work with closer to 6–8 weeks , but this is considered tight by many modern experts.

RSVP timing & planning backward

  • A common guideline is to set your RSVP deadline about 1 month before the wedding, giving you time to finalize seating charts and headcounts for your venue and caterer.
  • Work backward: pick your RSVP date, then mail invitations so guests have at least 4–6 weeks between receiving the invite and the RSVP cut‑off.
  • Before mailing, take one complete invitation to the post office to check weight and postage so none get returned at the last minute.

Quick example timeline

  • Save-the-dates: 8–10 months before (especially if many guests are traveling).
  • Order invitations: 4–6 months before so you have time for design, printing, and assembly.
  • Mail invitations: 2–4 months before , choosing the earlier end for destination, holiday, or high‑travel weddings.

TL;DR: If your wedding is local and not on a holiday, mailing invitations about 8–12 weeks before the date (with RSVPs due a month before) will work well for most couples.
