It is the second week of January, the Test is on the telly, and someone has just texted to say they are bringing two extra people. You count the seats on the deck and come up three short. If you have ever wondered how many chairs for an outdoor setting is actually enough, the answer is not the number of people who live in your house.
It is the number who turn up on your busiest afternoon of the year. This guide gives you a simple formula, a way to test it against the table you already own, and the difference between seats you leave out and seats you can produce in thirty seconds. If you are still choosing the table itself, start with our outdoor dining settings and work backwards from there.
How many chairs for an outdoor setting? Start with the formula
Use this: household + regular guests + 2. Count everyone who lives at home. Add the people who genuinely turn up most months — the neighbours, your sister and her partner, the kids' friends who never seem to leave. Then add two for the ones you did not plan for.
A couple with two children who host another family most months lands on eight. A retired pair in Adelaide who have friends over for Sunday lunch land on six. A share house of four in inner Brisbane, where everyone brings someone, lands closer to ten.
The +2 is not padding. It is the margin that stops you carrying kitchen chairs outside halfway through lunch, which is the moment most people discover they had undercounted by exactly two. And if the day still outgrows that margin, our guide on how to seat extra guests outside without buying a bigger table covers the on-the-day fixes.
Test the number against your actual table
A number on paper is only useful if the chairs fit around the table you own. Allow roughly 60 cm of table edge per person as a planning figure. Then leave 90 cm to 100 cm of clear floor behind each chair, so people can stand up without the whole row shuffling in.
That second measurement is where most alfresco areas come unstuck. A table that seats ten on paper seats six comfortably once it is pushed against a wall, or hemmed in by a BBQ and a pot plant. Walk the space with a tape measure before you buy anything, and mark the chair positions on the ground with masking tape if you are unsure.
Chair shape matters here as much as chair count. The Callala Bay Chair ($169) is an easy one to plan around, because a padded sling seat on a white frame reads lighter around a crowded table than a bulky cushioned armchair does.
Core seats, spares and benches: three different jobs
Once you know your number, you do not have to reach it with identical chairs. Most Australian households are better off with a core set that lives outside all year and a handful of spares that live somewhere dry until the numbers grow.
| Seat type | Best for | Watch out for |
|---|---|---|
| Fixed dining chairs | The everyday seats you leave out | They take up floor space twelve months a year |
| Folding chairs | Spare seats for big lunches | You need somewhere dry to store them |
| Backless benches | Adding people along one long side | No back support for a three-hour lunch |
| Beach and carry chairs | Overflow, kids and the lawn | They sit too low for a dining table |
The Teak Folding Chair ($149) is built for that second job. It folds up for storage, so a few can sit behind a door or in the shed until you need them, and each one is hand made from FSC certified plantation Indonesian teak. Left alone the timber ages to a silvery grey; oil it if you would rather hold the colour.
If your table has a long straight side, a Teak Backless Bench ($283) does something a chair cannot. It slides right under the table when nobody is sitting on it, so the seats disappear instead of crowding the walkway. It comes in four lengths: 45 cm, 120 cm, 180 cm and 210 cm. All of them measure 41 cm wide and 46 cm high, so check your table apron height before you choose.
Browsing outdoor dining chairs with those three jobs in mind is far quicker than scrolling through everything at once.
Where the spares live — and why January is the real test
Storage is the part people skip, and it is the reason spare chairs end up unused. January audits your number honestly: the Australia Day long weekend, school holidays, cousins down from Toowoomba, and a run of forty-degree days where everyone eats outside because the house is warmer.
Where the spares live depends on where you live. A house in Perth or Ballarat usually has a shed or a garage. An apartment in Sydney or Melbourne often does not, and many strata by-laws limit what can be stored on a balcony. Rules vary by building, state and council, so check with your body corporate or local authority before you assume the balcony counts as storage.
Humidity is worth planning for too. In Brisbane and along the NSW north coast, timber chairs stored in a damp shed will grow mould given half a chance, so keep them off the concrete slab and let air move around them. If you regularly seat more than ten, our guide to outdoor entertaining for large groups goes deeper on table layouts and traffic flow.
Then there is genuine overflow: the kids, the lawn, the beach at the end of the street. The Lesands Beach Chair ($69.95) is lightweight and compact, with a carry strap and a non-rust aluminium frame. Two or three can simply live in the boot of the car.
How many chairs for an outdoor setting — frequently asked questions
How many outdoor chairs do I need for a family of four?
Six is the practical minimum for a family of four. The formula gives you four household seats plus two spares, and that covers a set of grandparents or one extra couple without any rearranging. Move to eight if you host another family regularly.
Should I buy all my outdoor chairs at once?
Buy the core set in one go and add spares later. Chairs from the same range sell out or change colour between seasons, so the seats you use daily should match. The spares can be a deliberately different style without it looking like a mistake.
Do benches count as chairs when I am counting seats?
Count a bench by its length rather than as a single seat. Allow about 60 cm per person, so a 180 cm bench realistically seats three adults. Remember there is no back support, which suits kids and short lunches better than long afternoons.
What is the cheapest way to add two extra outdoor seats?
Folding chairs are the cheapest way to add seats you will actually use. They cost less than a full dining chair, they store flat, and they are not taking up deck space for the eleven months of the year you do not need them.
Do spare chairs need to match the dining setting?
No, spare chairs do not need to match. Staying inside one colour family is enough to keep it looking deliberate, and the Eton Chair ($244), with its powder-coated aluminium slat frame and base cushion, sits happily beside a table you already own.
Shop the range
Work out your number first, then shop to it — it is a far cheaper exercise than buying twice. Browse outdoor chairs and benches for both the everyday seats and the folding spares. We deliver Australia-wide, delivery is free on orders over $100, and installation is available on request.
