How Many Wedding Invitations to Order
The most common ordering mistake is counting guests instead of households — and ending up with nearly twice as many invitations as you need. Here's the simple way to get the number right, with a worked example.
The formula
- Count households, not heads. A couple gets one invitation. A family gets one. A single guest gets one. This is the single biggest factor — and the easiest to get wrong.
- Add 10–15% extra invitations. For keepsakes (you, both sets of parents, the photographer), the inevitable addressing mistakes, and any B-list additions later.
- Add even more spare envelopes. Envelopes are where slips of the pen happen; ordering 15–20 extra is cheap insurance.
Worked example: a 100-guest wedding
| Step | Calculation | Result |
|---|---|---|
| Guests | — | 100 |
| Convert to households | ~100 ÷ 1.8 avg per household | ≈ 56 invitations |
| Add 15% buffer | 56 × 1.15 | ≈ 64 invitations |
| Spare envelopes | 64 + ~18 | ≈ 82 envelopes |
So a 100-guest wedding lands near 64 invitations and ~82 envelopes — far fewer invitations than the headcount suggests, but more envelopes than invitations.
Why households, not guests?
Because a single invitation is addressed to everyone at one address. "Mr. and Mrs. Bennett" is one invitation for two people; "The Bennett Family" is one invitation for four. Counting heads doubles your order and your cost. If you've already built a guest list, count the lines on your envelope address list — that's your invitation number.
Don't forget the keepsake copies
- One for you and your partner
- One for each set of parents
- One for your photographer (for flat-lay detail shots)
- One or two for your album / framing
If you're printing them yourself
Printing at home or designing digitally changes the maths entirely — you can run off exactly the number you need, plus reprints are free if you make a mistake. That's one of the quiet advantages of a DIY approach: no minimum order, no over-buying, and you can print a few extra keepsakes at no real cost. Design once in the editor, then print as many as you like.
Order envelopes generously, invitations carefully
Reprinting invitations is expensive and slow; spare envelopes are cheap. Get the invitation count right (households + 15%), but be liberal with extra envelopes so a single addressing slip never means a reprint.
Print exactly the number you need
Design your invitation free in the editor and print as many — or as few — as you like. No minimum order, no watermark, no sign-up.

How many wedding invitations do I need for 100 guests?
Around 55–65 — not 100. You order one invitation per household, not per guest, then add about 10–15% extra for keepsakes and mistakes. Roughly 64 invitations is typical for 100 guests.
Do I order one invitation per guest or per household?
Per household. A couple, a family, or a single guest each receive one invitation addressed to their household. Counting individual guests roughly doubles your order and cost.
How many extra wedding invitations should I order?
About 10–15% over your household count, for keepsakes, addressing mistakes and last-minute additions. Order even more spare envelopes, since that's where most errors happen.
Should I order extra envelopes?
Yes — more than you think. Envelopes are where addressing slips occur, and they're cheap compared with reprinting invitations. Ordering 15–20 spare envelopes is sensible insurance.
Does DIY printing change how many I order?
Yes. Printing at home or designing digitally removes minimum orders entirely — you print exactly what you need, and reprints cost almost nothing if you make a mistake.
