Table mix: how many twos, fours and sixes

Walk through many restaurants on a busy Friday and you will see the same thing: couples at tables for four, two empty chairs at each, while a party of four waits at the bar for a table to come free. The room is full, the diary says there is no space, and yet a fifth of the seats are empty. The problem is not the number of seats. It is the table mix.

Table mix is the number of tables of each size in the room: how many twos, fours, sixes and larger tables you have. Most venues inherit their mix from whoever furnished the room, or from the furniture supplier's standard package, and never check it against the parties that actually book. A mix that matched the room's guests five years ago may not match them now.

This guide shows how to work out the right table mix from a month of your own booking data, how to measure the seats you are losing, when combining tables is better than buying more of them, and how to test a new mix before spending anything. Every figure in it is an example, not a benchmark.

Table mix describes the room in terms of table sizes: twelve twos, ten fours, three sixes and one round table for eight, for example. It is different from the number of seats. Two rooms with sixty seats can serve very different numbers of guests, depending on whether those seats come in tables that match the parties that book.

The mix matters because parties do not split. A party of three needs a table for three or four; it cannot use half of one table and half of another. Every time a party sits at a table bigger than itself, the extra seats are lost for the length of the meal.

A table mix that does not match your guests costs you in three ways:

The effect is largest on the busiest nights, when every seat matters. A room with the wrong table mix can feel full at seventy per cent of its seats.

The simplest way to see whether your mix fits is covers per table: the average number of guests seated each time a table is used, compared with the number of seats it has. A four-top that seats an average of 2.4 guests is using sixty per cent of its seats.

Work it out for each table size from a few weeks of your own data. An invented example:

In this example, the twos are doing their job, the fours are mostly seating couples, and the sixes are often seating fours. The room would serve more guests with more twos and fewer fours.

Start with the parties that actually come. Take a month of bookings and walk-ins, and count them by party size: how many ones, twos, threes, fours, fives, sixes and larger. Split the count by service if your services differ, because a weekday lunch and a Saturday dinner often bring very different parties.

A month is long enough to smooth out an unusual night and short enough to reflect your guests as they are now. Include walk-ins if you can; they are often mostly twos, and leaving them out makes large parties look more common than they are.

Now set the parties against the tables. If sixty per cent of your parties are twos and only twenty per cent of your tables are twos, most couples are sitting at fours. If parties of five and six make up ten per cent of bookings and you have no table that seats them without joining, those bookings take two tables each.

A simple comparison, the share of parties of each size against the share of tables of each size, usually shows the mismatch at a glance. Do it separately for your busiest service, because that is where the mismatch costs most.

With the party sizes and the current tables side by side, sketch a better mix. An invented example, for a room of about 60 seats:

The better mix has fewer seats, yet on a busy night it seats more guests, because couples sit at twos and fours stay free for parties of four. Fitting parties into tables is a version of a well-known puzzle in mathematics, the bin packing problem: the right sizes of container matter more than the total space.

In many restaurants, the four-top is the default table, and it is often the wrong one. Couples are the largest group of guests in many venues, and every couple at a four leaves two seats empty. Fours are flexible, which is why they are popular, but a room made mostly of fours gives up a great deal of capacity on busy nights.

Many venues do better with more twos, placed so that two of them can be pushed together to make a four. The room then serves couples at twos and fours at joined twos, and seats far fewer empty chairs.

Large tables are expensive in space: a table for eight that seats four on most nights is the most wasteful table in the room. For many venues, combining tables is better than owning large ones. Two fours become an eight, three twos become a six, a row of twos becomes a long table for a celebration.

Combining tables works best when it has been planned:

A room planned for combining can seat parties of two to ten with far fewer empty seats than a room of fixed tables.

Table shape affects the mix as much as size. Square tables join easily into longer tables and are the most flexible. Round tables are sociable and suit groups of four to six, but they do not join well. Long tables suit groups and communal seating, but small parties at a long table feel lost.

Most rooms benefit from a mix of shapes: mostly square twos and fours that can join, a few rounds for groups who want to face each other, and perhaps one long table for larger parties or communal dining.

A banquette along a wall, with small tables in front, is one of the most flexible arrangements a room can have. The tables can be split for couples or pushed together for a group, and the banquette seats as many as the tables need. Booths are less flexible: a booth for six is a booth for six, even when a couple sits in it.

If guests love your booths, keep them, and use them for the parties that fit. If they are often half empty, consider whether a banquette would serve the room better.

Single diners and many couples are happy at a bar or counter, especially for a quick meal. Bar and counter seats take a lot of small parties off the dining tables, freeing those tables for the parties who need them. If your data shows many ones and twos, and many of them are walk-ins, more counter seating may be the cheapest way to improve the mix.

The right mix for a weekday lunch is often not the right mix for a Saturday dinner. Lunch may be mostly ones and twos in a hurry; Saturday dinner may be fours, sixes and celebrations; Sunday lunch may be families. A fixed set of tables cannot match all of them perfectly.

This is where flexible tables matter most. A room of square twos that join into fours and sixes can be set for lunch with many twos and for Saturday with many fours, without buying anything. Our guide to a seating plan for a room that changes nightly covers standing layouts for each kind of service.

The ideal mix on paper has to fit the room. Walkways need to stay wide enough for servers with plates and for wheelchairs. Pillars, doors and the kitchen pass take space. Some tables need to be accessible, with step-free routes and room beside them. A restaurant floor plan drawn to scale shows whether a new mix will actually fit.

Change the mix on the plan before changing it in the room. Our guide to designing a restaurant floor plan that sells covers spacing, routes and the tables guests prefer.

You rarely need new furniture to test a new mix. Rearrange what you have: split some fours into twos if they are made of two smaller tables, borrow tables from a private room, push fours together for groups and leave twos for couples. Run the new arrangement for a few busy weeks and compare covers per table, waits and turned-away guests with the weeks before.

Look at any new arrangement in 3D as well as on the plan before moving the furniture. Seeing the room at eye height shows whether tables feel cramped and whether the routes still work. Only buy new tables once the test has shown the mix works.

Your booking capacity is limited by your tables as much as by your seats. If online booking offers a time only when a table of the right size is free, the table mix decides how many bookings of each size the diary can take. A room with few twos will show full to couples sooner than it should.

When the mix changes, review the booking rules that depend on it: which tables can be booked online, which party sizes each table takes, and how many large parties the diary accepts. Our guide to booking capacity covers how capacity is set by service.

Most booking systems let you set, for each table, the party sizes it takes. Use this to protect the mix. A four-top that takes parties of three or four, but not two, keeps the fours free for the parties that need them on busy nights; on quiet nights, the host can still seat a couple there by hand.

Set the rules to match your mix, and review them whenever the mix changes. Our guide to table assignment covers how hosts seat parties on the night.

The mix of parties changes through the year. December brings office parties and family groups; summer brings tourists in twos and fours; school holidays bring families. A terrace adds tables in summer, often in a different mix from the dining room.

Check your party sizes each season, and adjust the mix with flexible tables rather than buying for the busiest month. A mix that is right for eleven months is better than one that is perfect for one.

After changing the mix, measure the same things you measured before: covers per table for each table size, table utilisation, waits at the door, and how many parties were turned away. Compare the same services over the same number of weeks.

If covers per table rise and waits fall, the new mix is working. If large parties now wait longer, add a combination for them. Our guide to turn times covers how table size also affects how long each table stays.

Odd-sized parties are where the mix is tested hardest. A party of three usually sits at a four, leaving one seat empty, and a party of five usually sits at a six. Neither is a problem in small numbers, but if threes are a large share of your bookings, a few tables for three, or round tables that seat three comfortably, can save a lot of seats.

Look at how many threes and fives you get on your busiest nights. If they are rare, seat them at fours and sixes and accept the empty seat. If they are common, design for them.

Families change the mix in ways a count of party sizes does not show. A party of four with a pram needs a table with space beside it; a party of five with two high chairs needs a table at the end of a row, not in the middle of the room. If families are a large part of your trade, especially at weekend lunches, make sure the mix includes tables in places that can take them.

Note the tables that work for families on the floor plan, and keep them for families on the services where they book most.

An invented bistro with 60 seats has ten fours and ten twos. Its booking data for a month shows that 58 per cent of parties are twos, and that on Saturdays its fours seat an average of 2.5 guests. Couples wait for twos while fours sit half empty, and parties of four are turned away at eight.

The bistro replaces four of its fours with eight twos made to join into fours, and sets the remaining fours to take parties of three or more online. On Saturdays, couples sit at twos, fours sit at fours or joined twos, and the room seats more guests from the same 60 seats. Covers per table for the fours rise from 2.5 to 3.5, and the wait for a four at eight almost disappears.

servearound shows the figures a table mix is built from. Reservation analytics break bookings and covers down by party size, with each size's share, no-show rate and cancellations, and can be filtered by shift. Table analytics show seatings, covers, utilisation, revenue per seated hour and the median seating time for each table and zone, and the floor plan can be shaded by any of them, so the tables that waste seats stand out. See Analytics.

In the floor plan designer, you place round, square, long and bar tables with their seats and see the room in 2D or in 3D before moving any furniture. Each table's booking rules set the party sizes it takes and whether it can be booked online, and on the night staff merge and split tables for the parties that come. Coming next is the Digital Twin, with your own tables and chairs made into 3D from photos, so the plan looks like your room. See the reservations module.

The number of tables of each size in the room: how many twos, fours, sixes and larger tables you have.

Count a month of parties by size, compare the shares with your tables, and sketch a mix that matches, starting with your busiest service.

The average number of guests seated each time a table is used. Compared with the table's seats, it shows how many seats are wasted.

Often not. If most parties are twos, a room of fours leaves many seats empty. Twos that join into fours are usually more flexible.

When large parties are occasional. Joined tables serve them when needed and become small tables again afterwards.

Square tables, which join cleanly into longer tables. Rounds suit groups but do not join well.

Rearrange the tables you have for a few busy weeks and compare covers per table, waits and turned-away guests with the weeks before.

Yes. Online booking depends on tables of the right size being free, so the mix decides how many bookings of each size the diary can take.

Each season, using your party sizes, and whenever the menu, the room or your guests change.

At a four, if threes are rare. If they are a large share of your bookings, a few tables for three or round tables that seat three comfortably save seats.

Table mix decides how many of your seats are actually used. Count a month of your own parties by size, compare them with your tables, and measure covers per table to see where seats are wasted. Most rooms with many couples do better with more twos that join into fours, and fewer large tables.

Plan combinations of tables that join cleanly, keep the mix within what the floor plan allows, test new arrangements with the furniture you have, and set each table's booking rules to protect the mix on busy nights. Review it every season, and the room will seat more guests without a single extra chair.
