How to
How many tables do you need for your wedding?
Guests divided by seats per table, rounded up, plus a little slack. Here is the math, and what it looked like for 120 guests.
Updated
The number of tables decides more than it seems. It sets how full each table feels, whether families can stay together, and how the room looks from the door. It is also one of the first things a venue asks. The math is simple, but three details trip people up: the head table, the table sizes, and slack.
The chart below is a real example. We pasted a made-up list of 120 guests into Tablecharm. The starting room had a head table and six rounds of eight. The app looked at the list and said: "Your 7 existing tables provide 48 seats for 120 guests (the head table stays free for the couple and wedding party). We will add 8 round tables of 10, keeping your existing tables. Everyone will have a seat." We accepted, and it solved.
The basic math
Divide the number of guests by the seats at each table, and round up:
- 120 guests at rounds of ten: 12 tables.
- 120 guests at rounds of eight: 15 tables.
- 100 guests at rounds of ten: 10 tables.
- 150 guests at rounds of ten: 15 tables.
That number is the floor, not the plan. A room at exactly its capacity has no room for a family of five that will not split, or for the plus-one who replies late.
Leave the head table out of the count
The head table, or sweetheart table, is not a guest table. Count the people at it separately and subtract them from the list before you divide. If the couple and six attendants sit at the head table, a 120-guest wedding has 112 guests to seat at the other tables.
Tablecharm works the same way. The head table is kept for the couple and anyone you tag "wedding party" or place there, and its seats are not counted as room for everyone else. That is why the room plan above says the head table stays free.
Rounds of eight, ten, or a mix
Round tables that seat eight or ten are the usual venue stock. How many fit at a given round depends on its diameter, the chairs and the centerpieces, so ask your venue for their tables and seat counts.
Mixing sizes is common and useful. Small households fit neatly at eights, and big families stay whole at tens. The chart above does exactly this: it kept the six existing rounds of eight and added rounds of ten for the rest. In the editor you can also add small rounds of six, banquet tables of twelve, or a two-seat sweetheart table.
Add slack on purpose
Plan a few more seats than guests: roughly one open seat for every table or two while replies are still coming in. In the chart, 120 guests have 128 seats, so the solver could keep every household together and still leave some tables a seat or two light.
Spread the slack out. Eight tables with one open seat each look full and friendly. One table with eight empty chairs looks like a mistake.
Check the count against the room
Finally, make sure the tables fit the room with space to walk, a dance floor and the bar. The venue's floor plan is the authority. If you want a starting picture, the venue layouts show the four room shapes the Tablecharm editor has, and switching between them rearranges your tables in one click. The solver fills the tables you place; it never adds furniture you did not ask for.
Questions couples ask
How many tables do I need for 100 guests?
At least ten rounds of ten or thirteen rounds of eight, plus the head table. One more table adds flexibility. There is a full walk-through in the 100 guest guide.
How many tables do I need for 150 guests?
At least fifteen rounds of ten or nineteen rounds of eight, plus the head table. See the 150-guest chart for a solved example.
How many people fit at a round wedding table?
Usually eight or ten. Ask the venue for their exact tables and set each table's seat count to match.
Does the head table count toward the number of tables?
Count it as a table for the venue's furniture order, but not as seats for guests. Seat the head table first, then divide the remaining guests.
