What is a typical RSVP acceptance rate for weddings?

For local or regional weddings, expect 75–85% of invited guests to attend. Destination weddings typically see 50–65% acceptance. These figures vary by how close guests are to the couple and how far they need to travel.

Should I include plus-ones in my invite count?

Yes. Enter the total number of individual people invited, including all plus-ones and children. This gives the most accurate attending estimate.

How many guests fit at a standard round table?

Most caterers use 8- or 10-person rounds. For a cocktail-style reception with rectangular tables, 6–8 per table is common. Adjust the "guests per table" input to match your venue's setup.

How are catering quantities calculated?

The estimates use industry-standard per-person guidelines: roughly 1 lb of food per guest across main course and sides, 1 wedding cake slice per person, and approximately 4–5 drinks per adult over a 4-hour reception. Add 10% buffer for safety.

Why should I add a buffer to these estimates?

RSVPs can be inaccurate — last-minute guests arrive and some who RSVPd yes cancel. A 5–10% food buffer prevents running short without significant waste.
