How Many Tables Do You Need for a Wedding?

The short answer

Divide the guests who will sit at round tables by 8 for 60-inch rounds or 10 for 72-inch rounds, and round up. For 117 guests with a sweetheart table, that is 15 tables of 8 or 12 tables of 10. Then add your own table, a table for vendors who eat, and four to six service tables for the cake, gifts, cards and music, and check the room is rated for that many people seated, not standing.

Most answers stop at the division. The rental company, the caterer and the venue each need more than that, and they need the same number. This guide builds the full order for one wedding, step by step, so you can swap in your own count.

How many people sit at each table

Rental companies do not agree on this. One event rental company lists a 60-inch round at 6 to 8 guests and a 72-inch at 8 to 10. A rental software company's calculator uses 8 and 10, and notes that one more guest fits but feels cramped at a plated dinner. The difference is chairs, place settings and how much elbow room you want.

The decision rule: plan at the comfortable number, and keep the tight number for a buffet, where there are fewer plates and glasses on the table.

Table	Plan for	Tight
60-inch round	8	9
72-inch round	10	11
6-foot rectangle	6	8
8-foot rectangle	8	10

The tight number for a rectangle uses the ends: an 8-foot table fits four a side plus one at each end, and a 6-foot table three a side plus one at each end. Used from one side only, as a head table usually is, an 8-foot table seats four.

Ask your venue which tables it owns before you count. If it has 60-inch rounds, that settles the question, and you only rent what is missing.

The worked example: 117 guests

The Knot's 2026 Real Weddings Study found the average wedding had 117 guests, so the example uses that. Count the people who will actually be in the room: once replies are in, the guests who said yes, with their plus-ones and any children who need a seat. The two of you are not on that list, so you are counted separately.

With a sweetheart table. The two of you sit at a small table of your own, and all 117 guests sit at the round tables.

60-inch rounds at 8: 117 ÷ 8 = 14.6, so 15 tables, 120 seats, 3 spare.
72-inch rounds at 10: 117 ÷ 10 = 11.7, so 12 tables, 120 seats, 3 spare.

With a head table. Say ten people sit at it: the two of you and eight in the wedding party. Facing the room, four to an 8-foot table, ten people need three 8-foot tables in a row. The eight in the wedding party come off the guest count, which leaves 109 guests for the round tables.

60-inch rounds at 8: 109 ÷ 8 = 13.6, so 14 tables, 112 seats, 3 spare.

A few spare seats is right. They leave room for a late plus-one, and let a family of five sit together without splitting across two tables.

Spread the spare seats out

Rounding up leaves the last table part empty. Fifteen tables for 117 guests is not fourteen full tables and one with five people at it. It is twelve tables of 8 and three tables of 7, which looks full everywhere and gives three tables a little more room. Older relatives and families with small children are the ones to give the roomier tables to.

The tables that are not for guests

These are easy to forget in the rental order, and each needs a table and a cloth.

Your table, sweetheart or head.
A vendor table, if your contracts include a meal for the photographer, the band or the planner. Count their seats like guests.
Escort cards or the seating display, near the entrance.
Gifts and cards.
The guest book, often on the same table as the cards.
The cake.
The DJ or band, unless they bring their own.
The bar and any buffet or food stations, unless the caterer brings them.
Cocktail tables for the cocktail hour. Most guests stand with a drink, and a cocktail table serves two to four standing guests, so you need a few, not one per guest.

For the example, with a vendor table of four and six service tables, the order comes to 15 rounds, 1 sweetheart table, 1 vendor table and 6 service tables. Ask the venue which of these it already has.

Chairs, linens and centrepieces follow from the tables

Once the table count is fixed, the rest of the order is multiplication.

Chairs: seats at every table, including your own and the vendor table, plus 5 to 10 percent extra for a late addition. For the example with a sweetheart table: 120 + 2 + 4 = 126 seats, so order about 132 chairs.
Ceremony chairs: if the ceremony is in another space, either rent a second set or ask the venue whether staff can move the chairs during the cocktail hour.
Tablecloths: one per table, guest and service, each sized for that table. The rental company will match the cloth to the table.
Centrepieces: one per guest table. This is where 72-inch rounds save money: 12 centrepieces instead of 15.

Will it fit the room?

A room that holds 300 people at a standing party does not seat 300 at dinner. Building codes set a minimum floor area per person for each use. Under the International Building Code, a room with tables and chairs needs 15 square feet per person, while standing space needs 5. The same room holds about a third as many people at tables as standing.

That is the legal minimum, with nothing else in the room. The rental software company's planning figure is roomier: about 2,000 to 2,500 square feet of dining space for 120 guests at round tables, or about 17 to 21 square feet each. The dance floor, the bar and the band need space on top of that.

So the rule is simple. Ask the venue for its capacity for a seated dinner, the layout you are planning, not the largest number on its website. Then ask for a floor plan with your table count drawn on it. A good venue has drawn your layout many times before.

When to count

Twice. Count first from your guest list, before replies, to get a rental quote and check the room. Use the number you expect to say yes, not the number invited.

Count again after your RSVP date, when the replies are in. That is the number the rental company and the caterer need for the final order. Our guide to when to send invitations and set the RSVP date gives you that date. If the first count is more than the room holds, the guide to cutting a guest list has a fair method.

Then comes who sits where. The seating chart guide takes it from here, step by step.

Counting it in the app

In Yes, I Do, seating works from the guests who said yes, with their plus-ones counted as seats. With no tables yet, Add table makes enough tables of 8 for everyone attending. If your venue has rounds of 10, press and hold a table's name to change its seats. The screen shows how many people are attending and how many seats you have across how many tables, and each table shows how full it is, so a table that is over shows straight away. Auto seat then places everyone, keeping each side's family and friends together.

Yes, I Do

Seat everyone who said yes

Tables fill from the replies on your guest list, and moving someone to another table is one tap.

Questions

How many tables do I need for 100 guests?

At 60-inch rounds of 8, 100 ÷ 8 = 12.5, so 13 tables. At 72-inch rounds of 10, 10 tables. Your own table comes on top, then a vendor table if one is needed and four to six service tables for the cake, gifts, cards and music.

How many tables for 150 guests?

At 60-inch rounds of 8, 150 ÷ 8 = 18.75, so 19 tables. At 72-inch rounds of 10, 15 tables. Spread the spare seats across several tables rather than leaving one table half empty.

How many people can sit at a 60-inch round table?

Eight is comfortable for a plated dinner. One rental company lists 6 to 8, and a rental calculator uses 8, noting that a ninth fits but feels cramped. Keep nine for a buffet, where there is less on the table.

Is it better to have tables of 8 or 10?

Tables of 8 at 60-inch rounds are easier to talk across and suit a plated dinner. Tables of 10 at 72-inch rounds mean fewer tables, fewer cloths and fewer centrepieces, which saves money and floor space for a large wedding. Start from what the venue owns.

How much space do you need for 100 guests at tables?

The building code minimum is 15 square feet per person with tables and chairs, so 1,500 square feet for 100. A comfortable planning figure is about 17 to 21 square feet per guest, roughly 1,700 to 2,100 square feet, before the dance floor and bar. Ask the venue for its seated dinner capacity.

Do you need a separate table for vendors?

If your contracts include a meal for the photographer, band or planner, yes, or seats at a guest table. Count them in the chairs and in the caterer's numbers.
