How Many Invitations Do You Really Need?

The single most common stationery mistake is ordering one invitation per guest. You don't invite people one by one, you invite them by household, and that changes the number more than you'd expect. Get this right and you save money and avoid a frantic reprint.

Here's how to count properly, what buffer to add, and the extras most couples forget until it's too late.

Count households, not heads

A married couple living together gets one invitation. A family of four gets one invitation. Two flatmates who happen to both be on your list usually get one each, because they're separate invites even at the same address, though a couple at the same address share.

So before you order anything, go through your guest list and group it into invitation units: who's getting one envelope. A list of 120 guests very often shrinks to around 65 to 75 actual invitations once you've paired up couples and families. That's a big difference when stationery is priced per piece.

The quickest way to do this is to sort your list by household first. If your guest list lives somewhere structured rather than scribbled on a notepad, this takes minutes. A wedding website that lets you group guests into households (Build The Day does this) means your invitation count more or less falls out of the list automatically.

Add a sensible buffer

Once you've got your household count, do not order exactly that number. You want a buffer for three reasons: mistakes when addressing, last-minute additions, and keepsakes.

A good rule is to add roughly 10% to 15%, rounded up to the nearest sensible quantity. Many stationers price in batches anyway, so going from 70 to 80 often costs far less than you'd fear. The painful version is the opposite: realising you're three short and paying a small fortune for a tiny reprint run, assuming your stationer will even do one.

Keep two or three back as keepsakes for yourselves and possibly your parents. People always want one for the memory box, and they don't appreciate it until the box arrives empty.

Don't forget the B-list

If you're running a B-list (guests you'll invite if others decline), your invitation count needs to cover them too, but you order them as part of the same print run rather than separately. Trying to match the exact paper, ink and printing later is rarely worth it, and a second small order usually costs more per piece.

Send the first round early enough that you can post the B-list invitations once the initial replies come in, without it being obvious. Six to eight weeks before the wedding is the latest you'd want a guest receiving theirs, so build that into your timing.

The pieces people undercount

The invitation is only one item in the envelope, and the extras add up. Before you finalise quantities, think about:

• RSVP cards and their envelopes, if you're not collecting replies online.
• Detail cards for travel, accommodation or dress code.
• Save-the-dates, which you'll have ordered months earlier in roughly the same household count.
• Evening invitations, which are a separate, usually larger, count for guests joining after the meal.

Evening invites in particular catch couples out. They're a different list and often a much bigger one, so count them as their own batch with their own buffer.

Let the website carry the extras

You can shrink your paper order considerably by moving the detail cards online. Travel directions, parking, the running order, accommodation suggestions and the RSVP itself all sit comfortably on a wedding website, which means a simpler, cheaper invitation that just points guests to the link.

That's the modern setup most couples land on: a beautiful printed invitation with the essentials, a short web address, and everything else (replies, meal choices, the lot) handled online. Build The Day gives you the website and the online RSVPs, so the envelope can stay light.

Count by household, add 10% to 15%, keep a couple back, and remember the evening list is its own thing. Do that and you'll order once, get it right, and have one less small fire to put out closer to the day.
