よくある質問
Why do families count as 3.5 guests?
The 3.5 average accounts for a mix of family sizes — couples with no children, families with one child, and families with two children.
Should I order extra invitations?
Yes — order 10–15% extra for last-minute additions, keepsakes, addressing mistakes, and late RSVPs.
What is the plus-ones percentage?
This is the percentage of single guests you expect to bring a plus-one. A typical estimate is 30–50% depending on the event formality.
