Show the math

Guests are divided by seats per table and rounded up, since a partly-filled table still needs a whole table:

tables = ⌈guests ÷ seats per table⌉

Add a head table separately if the couple or wedding party sits apart. The “last table” figure helps you balance seating so no one sits almost alone.

What this does

A seating chart calculator finds how many tables you need for a guest count at a given seats-per-table, plus an optional head table, with empty seats and the last-table count.

How to use it

  1. Enter your guest count.
  2. Set the seats per table.
  3. Add a head table if needed.
  4. Read the tables and empty seats.

How it works

Always round up — a partly filled table still needs a whole table. A 60-inch round seats 8–10; a 72-inch round seats 10–12.

tables = ⌈ guests ÷ seats per table ⌉

Understanding your result

Always round up, because a partly filled table still needs a whole table. The empty-seats and last-table figures are the signal to act: a near-empty final table usually means nudging the seats-per-table up or merging guests so no one sits almost alone. Larger tables seat more but eat floor space, so balance the count against room for a dance floor.

Example

90 guests at 10 per table need 9 tables with no empty seats.

Frequently asked questions

How many tables do I need?

Divide your guest count by the seats per table and round up, a partly filled table still needs a whole table. Add a head table separately if needed.

How many seats per table is standard?

A 60-inch round seats 8 comfortably or up to 10; a 72-inch round seats 10–12. Pick the number that suits your venue and décor.

What is the “last table” figure?

It shows how many guests sit at the final, partly filled table, so you can rebalance seating and avoid leaving one or two people almost alone.
