**The short answer:** order **one wedding invitation per household, not per guest**, then add **about 10% extra**. A household is one single guest, one couple, or one family living at the same address. So a list of 150 guests usually needs somewhere between 75 and 100 invitations, depending on how many couples and families are on it.

Ordering one per person is the most common and most expensive mistake. Here is how to get the exact number.

## Do you order wedding invitations per guest or per household?
**Per household.** One invitation goes to each address and names everyone at that address who is invited:

- **A single guest:** 1 invitation ("Emily Carter")
- **A couple** (married, engaged or living together): 1 invitation ("Sarah & James Smith")
- **A family:** 1 invitation ("The Johnson Family", or the parents' names if only adults are invited)
- **A guest with a plus-one:** 1 invitation ("David Lee and Guest")

Two exceptions: adult children who live with their parents traditionally get their own invitation, and couples who live at different addresses get one each.

## How to count your wedding invitations, step by step
1. **Start from your guest list** (a spreadsheet works well) with one row per person.
2. **Group people by address.** Everyone who lives together and is invited goes in one group.
3. **Count the groups.** That's your number of invitations.
4. **Add about 10%** for extras (see below).
5. **Round up** to the printer's pack size if you're ordering printed cards.

Example: 150 guests, of whom 90 are in 45 couples, 24 are in 6 families of four, and 36 are single guests. That's 45 + 6 + 36 = **87 households**. Add 10% (about 9) and order **96, or the next pack size up**.

## How many extra wedding invitations should you order?
Order **around 10% extra, and at least 5 to 10**. Extras cover:

- Addressing mistakes and smudged envelopes
- Guests you add after a decline (your B-list)
- Keepsakes for yourselves, both sets of parents and grandparents
- One or two for your photographer to style for the "flat lay" photos

Reordering a small batch later almost always costs more per card and can take weeks, so it's cheaper to order extras at the start.

## How many RSVP cards, envelopes and inserts do you need?
Match the invitation count for everything that goes in each envelope:

| Item | How many |
|---|---|
| Invitations | One per household + about 10% |
| Outer envelopes | Same as invitations, plus a few more for addressing mistakes |
| RSVP cards + reply envelopes | Same as invitations (skip them if guests reply online) |
| Details or map cards | Same as invitations, or only for guests who need them |
| Save-the-dates | One per household, sent to the same list |
| Thank-you cards | One per household that came or sent a gift |

5x7 invitations fit A7 envelopes (5.25 x 7.25 in). Buy envelopes in packs with a margin: addressing mistakes happen on envelopes more than on cards.

## What if your guest list changes?
It will. Most couples add and remove people after the first invitations go out, which is another reason for extras. If you print at home, it doesn't matter: you print exactly what you need, when you need it, and print one more for a late addition.

## Should you order printed or print at home?
**Print shops and online stationers** price per card, so the household count matters a lot: every extra invitation adds to the bill, and so does reordering.

**Printing at home** (or sending one PDF to a local print shop) means you pay once for the files and print as many as you need. Two 5x7 invitations fit on each US Letter or A4 sheet. See [how to print 5x7 invitations at home](/blog/how-to-print-wedding-invitations-at-home) for paper and settings.

**Digital invitations** need no count at all for guests who are happy with a link: send paper only to the households who will treasure it (often grandparents and older relatives), and a personal link to everyone else.

## One invitation per household, each with their names
With InviteBatch you paste your guest list one household per line ("Sarah & James Smith", "The Johnson Family", "David Lee +1") and get one invitation per household with those names printed on it. Duplicates are removed and look-alike names are flagged before anything is made. You get print-ready PDFs (two 5x7 cards per Letter or A4 page) plus a personal RSVP link for each household, for $49.99 one-time for up to 1,000 invitations. For 7 days after you buy you can add late guests free and print just their cards.

## FAQ

**How many wedding invitations should I order?**
Order one invitation per household (a single guest, a couple or a family living together), not one per person, then add about 10 percent extra for mistakes, late additions and keepsakes. A list of 150 guests often comes to somewhere between 75 and 100 invitations, depending on how many couples and families are on it.

**Do couples get one wedding invitation or two?**
One. A married or live-in couple shares one invitation addressed to both of them. Adult children who live at home traditionally get their own invitation.

**Do plus-ones need their own invitation?**
No. A plus-one is included on the invited guest's invitation, for example "David Lee and Guest". If you know the partner's name, write it on the same invitation.

**How many extra wedding invitations should I order?**
Around 10 percent, or at least 5 to 10 extra, covers addressing mistakes, guests you add later, and a few keepsakes for yourselves, your parents and your photographer.

**Do I need the same number of RSVP cards as invitations?**
Yes, one RSVP card and one reply envelope per invitation, plus the same extras. If guests reply online you can skip RSVP cards entirely.
