How Many Wedding Favors Do You Actually Need? The Per-Guest Math

Here's the short answer: order one favor per adult guest, plus a 10 to 15% buffer. Here's the long answer, because the short answer misses four situations that actually determine whether you'll finish the night with an empty table or a box of 40 unclaimed favors.

We ship a lot of favor orders. Almost every time a couple emails us after the wedding, the note is either "we had exactly the right number, thank you" or "I have 25 left over and I don't know what to do with them." The difference is rarely the couple's math, it's usually a variable they didn't plan for. Here's the checklist.

The base formula

Start here:

Favor count = (Adult guests attending) × 1.10

So for a 100-adult-guest wedding, you're ordering 110 favors. That's the per-guest rule (one each) plus a 10% buffer for broken ribbons, favors that get photographed and set aside, and the handful your coordinator hands to you and your partner at the end of the night.

That's the number if nothing else is going on. Most weddings have something else going on. Here are the adjustments.

Adjustment 1: kids at the wedding

Kids get excited about favors more than adults do. They also break them more often. Here's the rule:

  • Kids under 5: don't count them in your favor count. Give them a lollipop.
  • Kids 5 to 12: count them at one favor per child, not per family. They each want one.
  • Teenagers 13+: count them as an adult.

If you have a kids table with activity favors (stickers, a coloring book, a personalized keychain), you can skip the adult favor for them entirely. This is often cleaner.

Adjustment 2: per-guest or per-couple?

Some favors are per-person (a cookie, a keychain, a mini champagne bottle). Some favors are per-couple (a box of cookies, a candle, a shared item). Decide which yours is before you order.

Per-person favors: use the base formula above.
Per-couple favors: count couples separately. A wedding with 120 guests (60 couples + 20 singles) would need 80 favors, not 120.

A practical check: if the favor is something a single person can reasonably consume or use, it's per-person. If it's something two people would share (a bottle of olive oil, a jar of jam, a framed photo), it's per-couple.

Adjustment 3: favor bags versus favor boxes versus keychains

Different favor types have different leftover rates. From our data:

  • Keychain favors (like our hashtag keychains): nearly zero leftover rate. Guests take them because they're small and light.
  • Favor bags (our kraft treat bags filled with cookies, coffee, or candy): low leftover rate. Guests take them because they have something inside worth taking.
  • Favor boxes (our personalized favor boxes with ribbon): moderate leftover rate. Guests take them if the box is pretty, skip them if the box looks generic. This is why we design ours with a visible custom detail.
  • Shot glasses, koozies, matchbooks: medium-to-high leftover rate. Guests are more selective about bar-themed favors.

Adjust your order accordingly. If you're ordering keychains or bags of cookies, buffer is 10%. If you're ordering something guests might leave behind, buffer is 15%, not because you'll have fewer favors than guests, but because you don't want a favor table looking empty at 7pm when the guests arrive.

Adjustment 4: favor-table display vs. place-setting

How you distribute favors changes what you order.

  • At each place setting: exactly one per adult guest (or per couple). Minimal buffer, 5%. No one grabs extras from their own plate.
  • On a favor table: base formula. Some guests will take two, some will forget theirs entirely.
  • Handed out at the send-off: base formula. Count leavers, not RSVPs, maybe 80% of your guest list will actually be there at 11pm.

When to skip favors entirely

Genuinely good reasons to not order favors:

  • Your venue is a sit-down dinner with heavy food and guests aren't taking anything extra home.
  • You're doing a late-night snack bar, people remember the food, not the takeaway.
  • Your budget is tight and you'd rather spend the $300 on better florals or a longer bar. This is legitimate and increasingly popular.
  • Your guests have flown in and can't easily pack a favor home.

Bad reasons to skip favors:

  • "I think guests don't want them." They often do. They don't want generic ones.
  • "I don't want to assemble them." Order them pre-assembled from us. We pre-tie the ribbons.

The quick reference

If you want the formula to keep on your phone:

Favor count = (Adult attendees × 1.10) + (Kids 5 to 12)

Plus:

  • Per-couple favor? Halve it (minus singles).
  • Favor table rather than place setting? Keep the 10% buffer.
  • Bar-themed favor guests might skip? Bump to 15% buffer.

That's the answer. For a typical 120-guest wedding with 10 kids, you're probably ordering 132 favors (not 120 and not 150).

Order in sets of the right size

A production note. Our favor boxes come in sets of 12; our favor bags in sets of 24. Order the next set up from your exact number. 132 favor boxes = order 144 (twelve sets of 12). No one regrets having a few extras; lots of couples regret cutting the number close and running out.
