How It Works
How many wedding invitations do you actually need?
The most common mistake in ordering invitations is printing one per guest. Couples and families share an invitation, so the number you need is lower than your headcount. But you also don't want to print exactly that number, because you will need a few spares. This calculator does both steps and gives you one number to take to your printer.
The math, step by step
You enter two things: your total guest headcount, and the percentage of guests who are arriving as couples or families. The calculator then works in four steps:
- Paired guests are your headcount times that percentage. They are counted two to a household.
- Solo guests are everyone else, one invitation each.
- Households are paired guests divided by two, plus solo guests, rounded up. This is how many envelopes you will actually mail.
- Invitations to print are households plus a 15% overage buffer, rounded up.
A worked example
Say you have 120 guests and about 70% of them are coming as couples or families. That is 84 paired guests, which is 42 households, plus 36 solo guests, for 78 households to mail. Adding the 15% buffer gives 90 invitations to print. A few more examples: 100 guests at 70% is 65 households and 75 invitations; 150 guests at 80% is 90 households and 104 invitations; 200 guests at 60% is 140 households and 161 invitations.
Why the extra 15%?
Invitations get ruined while you are addressing them, a name gets misspelled, a guest list changes, and you will want a few for keepsakes and for photographing your stationery. Ordering the extras with the first print run is far cheaper than a second small run later.
Where the estimate can be off
The calculator treats every pair of "paired" guests as one household. A family of four really is one invitation, but this method counts it as two, so if many of your guests are families with kids the result will run a little high. That is the safe direction to be wrong in, and you can lower the pairing percentage to fine-tune it. If you want exact numbers, count your actual households from your guest list and add 15%.
Invitation quantity questions
How many invitations do I need for 100 wedding guests?
If about 70% of your guests are coming as couples or families, you need around 65 households, and the calculator suggests printing about 75 invitations with the buffer. If most guests come alone it will be higher, and if almost everyone is a couple it will be lower.
Does every guest get their own invitation?
No. Couples and families normally share one invitation addressed to the household. Adult guests living at separate addresses, such as grown children, each get their own. See our invitation etiquette guide for addressing envelopes and handling children and plus-ones.
What percentage should I enter for guests arriving as couples or families?
Look at your draft guest list and estimate how many people are attending with a partner or family. Seventy percent is a reasonable starting guess and is the default, but your own list is the best guide. Move the slider and the result updates instantly.
Should I order extra envelopes too?
Yes. Envelopes are the part most likely to be ruined during addressing, so ask your printer to include extras, and check their minimum order quantity before you decide on a final number.
Do I need to count save-the-dates or RSVP cards separately?
This calculator gives the invitation count only. If your suite has separate RSVP cards or enclosure cards, you typically need the same number as the invitations. Save-the-dates go out earlier and are based on your draft list, so run the numbers again before you order them.
These numbers are planning estimates based on your inputs. Confirm final quantities with your printer before you place an order.
