Wedding Invitation Quantity Calculator
The number-one invitation budgeting mistake is ordering one card per guest. You mail one invitation per address — so a 120-person guest list is often only about 70 invitations. Enter your numbers below for an exact order quantity, including the spares you'll actually need.
Estimates round invitation orders up to the nearest 5 (printers' common increment). Households are an estimate from your average — your real address list is the final word. Re-confirm against a spreadsheet of addresses before you order.
Why you count households, not guests
A wedding invitation is addressed to a household, not a person. A married couple receives a single invitation; a family with two children still receives one; only your genuinely single guests each get their own. That is why a guest list of 120 people typically becomes roughly 70 invitations. Counting heads instead of addresses is the single most common reason couples over-order — sometimes by 30–40% — and pay for cards that go straight in a drawer.
The calculator estimates households by dividing your guest count by an average "share" figure. If your crowd is mostly established couples, 2.0 is realistic; if you have lots of single friends, drop toward 1.4; a family-heavy list with lots of children pushes the average up. For the final number there is no substitute for an actual address spreadsheet, but this gets you within a card or two.
The spare rule: 10–15% extra
Always order a cushion. Spares cover four predictable situations:
- Late additions. Almost every guest list grows after the first draft — a new partner, a forgotten cousin, a B-list bump after early "no"s.
- Addressing mistakes. Hand-calligraphy and even printed envelopes get spoiled; a smudge means a fresh start.
- Lost or damaged mail. A small number of invitations never arrive and need re-sending.
- Keepsakes. Keep one or two for yourself, a frame, or the wedding album.
The reason this matters financially: re-ordering 10 invitations later usually costs several times the per-piece price of the original run, because you pay setup, proofing and shipping again for a tiny batch. A 10–15% cushion up front is almost always cheaper than a reprint. See how many invitations to order for a fuller walk-through.
Save-the-dates, RSVP cards and envelopes
Once you know your invitation count, the rest of the stationery suite follows:
| Piece | How many |
|---|---|
| Save-the-dates | One per household — the same addresses as invitations. Send only to guests you are sure to invite. |
| RSVP / reply cards | One per invitation. Don't forget to stamp the return envelopes. |
| Outer envelopes | Your invitation count plus ~5% — addressing errors ruin envelopes faster than anything else. |
| Details / insert cards | One per invitation if used (directions, registry, website). |

How many wedding invitations do I need for 100 guests?
Far fewer than 100. Because couples and families share one envelope, 100 guests is usually about 55–65 households. Order that many invitations plus a 10–15% spare allowance — so roughly 65–75 invitations for a 100-guest list.
Do I count one invitation per guest or per household?
Per household. One invitation goes to each address: a couple gets one, a family with children gets one, and single guests each get their own. Counting heads instead of households is the most common reason couples over-order by 30–40%.
How many extra wedding invitations should I order?
About 10–15% extra. Spares cover late additions, addressing mistakes, lost mail, and one or two keepsakes. A small reprint later usually costs far more per piece than the original run, so a modest cushion is cheaper than a reorder.
How many save-the-dates do I need?
The same number as invitations — one per household, to the same addresses. Send them only to guests you are certain to invite, since a save-the-date commits you to a formal invitation later.
