Most outdoor tables get bought in the wrong order. People fall for a table first. Then it arrives and the chairs hit the wall every time someone stands up. Or the table seats six but the family is eight. The fix is simple. Measure your space, count your people, then shop. This guide covers both steps, with table sizes that work for two people up to twelve.
Start with your space, not the table
Take a tape measure out to your deck, patio or balcony. Write down the length and width of the area where the table will live. Now subtract the room you need to move. Allow about a metre of clear space on every side where someone will sit. That is enough to pull out a chair and walk behind it while people are seated. You can get away with 60 centimetres on a side nobody walks past. It will feel snug though.
Here is the quick maths. A patio 4 metres deep can hold a table about 2 metres deep at most, once chairs and walking room are counted. If a table pushes past that, the space will feel cramped even if everything technically fits.
One trick we always suggest. Mark the table footprint on the ground with masking tape. Leave it there for a day and walk around it as you normally would. You will know within an hour if it is too big.
How much table each person needs
Allow roughly 60 centimetres of table edge per person. That fits a plate, a glass and a set of elbows without bumping the next seat. If you like a generous spread of shared plates down the middle, look for a table at least 90 centimetres wide. Narrower tables work fine for coffee and drinks but get tight once serving bowls arrive.
Look at where the legs sit too. A leg at each corner leaves the long sides clear for chairs. A central pedestal keeps knees free at the ends instead. Neither is better. It just changes where people can sit comfortably, which matters when you are squeezing in one more seat at Christmas.
A size guide from 2 to 12 people
Every table is different, so always check the listed dimensions. As a starting point, these sizes tend to work:
- 2 people: a round or square table 60 to 80 centimetres across. Ideal for balconies and small courtyards.
- 4 people: a 90 centimetre square, or a round table 90 to 110 centimetres across.
- 6 people: a rectangle 150 to 180 centimetres long, or a round table 120 to 140 centimetres across.
- 8 people: a rectangle 200 to 220 centimetres long, or a round table about 150 centimetres across.
- 10 people: a rectangle 240 to 260 centimetres long.
- 12 people: a rectangle 300 centimetres or longer, or two smaller tables pushed together.
If your usual number sits between sizes, go up rather than down. An empty seat is never a problem. A missing one always is.
Rectangle, round or square?
Shape changes how a meal feels as much as size does.
Round tables are the most social option for small groups. Everyone faces everyone. Nobody gets stuck on a corner. They also suit tight spaces because there are no corners to walk into. If your space is a small courtyard rather than an open deck, our round versus rectangular seating maths for small courtyards runs the clearance numbers for a 3 x 3 m and a 4 x 3 m area. The catch is that a big round table puts the centre out of reach, so rounds top out at about eight seats in practice.
Rectangles are the workhorses. They suit long narrow decks, they seat big numbers efficiently and they can sit against a wall when not in use. Conversation tends to split into groups at a long table, which is no bad thing at a big gathering.
Squares suit square courtyards and groups of four. At larger sizes they share the round table problem. The middle gets hard to reach, and you lose the cosiness that made the square appealing in the first place.
Benches, extensions and other space savers
Two things can stretch a modest space further. Benches tuck fully under the table when not in use, and they fit an extra small person or two at a pinch. They work especially well on the wall side of a narrow deck where chairs would never be pulled out fully anyway.
Extension tables are the other option. They live at a compact size most of the year and open up when the crowd arrives. If you entertain in bursts, at Christmas and birthdays and not much in between, an extension table saves you living with a huge table year round. If Christmas lunch is the day that really decides your table size, our guide to the best outdoor dining sets for seating 8, 10 and 12 compares extension sets, large fixed settings and bench seating side by side.
Check chair sizes as well. Wide, deep chairs with arms need more room per seat than the 60 centimetre rule suggests. Slimmer armless chairs buy that room back. Browsing dining chairs separately is worth doing if you want to mix and match.
The measurements people forget
A few small checks save big headaches on delivery day.
Door and gate widths. Larger tables often arrive with the top in one piece. Measure the narrowest point on the path to your outdoor area, including side gates and sliding doors.
Steps and edges. If your deck has a step down, keep chairs at least a metre back from the edge so nobody tips over it when they lean back.
The umbrella question. If you plan to shade the table with a centre umbrella, check the table has an umbrella hole. If you would rather keep the tabletop clear, a cantilever umbrella can reach over from the side instead.
Overhang. Tabletops usually overhang their legs. Two tables with the same top size can have very different leg positions, which changes how many chairs actually fit. Check both sets of dimensions before you decide.
An outdoor table is a purchase you live with for years, so it earns an evening with the tape measure first. Once you have your numbers, our outdoor dining settings cover the full spread of sizes, and you can browse tables on their own if you already have chairs you love.
