Outdoor Dining Set Sizes: Fit a UK Patio With 90cm Clearance

Allow about 60cm of table edge per person, then add 90cm of clearance behind every chair: that sum is your footprint. The usual anchors are 120cm for two to four people, 150cm for four to six, 180cm for six, and 200 to 240cm for larger groups, according to Seek & Ramble. We stock outdoor dining sets, so you can match your measurements to a real table.
TL;DR:
- Measure usable patio dimensions after subtracting railings, planters, and door swings, then tape the footprint and preserve the busiest walking route.
- Allow 90cm behind chairs for standing space, increase it to 110cm where people pass behind diners, and retain full clearance near doors and barbecues.
- A 180cm table seats six with chairs or up to eight with benches, which need less side clearance because they do not slide back.
- Choose rectangular tables for long, narrow decks and flexible seating, round tables for intimate corners, and compact square or bistro sets for two to four people.

How do you measure your patio, deck or garden area?
Before you look at a single product, measure the space you actually have. A tape measure, masking tape and a notepad are enough. Work in centimetres, because that is how table dimensions are listed.
- Measure the full length and depth of the area, and note any steps or drops at the edges.
- Mark fixed obstacles: door swings, the barbecue, planters and drainpipes.
- Measure railings or balustrades that cut into the depth, then subtract that from the usable figure.
- Record the width of your busiest walking route, such as the path from the back door to the shed.
- Stick masking tape along the edges of the usable zone so you can see it on the ground.
The number that matters is the usable area, not the total. A patio may offer less usable depth than its full measured depth once a balustrade and a planter are taken out. Write both figures down, because the smaller one is the one that decides your table.
How much clearance do chairs and movement need?
According to Seek & Ramble, each person needs about 60cm of table edge, which covers a place setting and a little shoulder room. Behind the chairs, Seek & Ramble suggests 90cm so people can stand up and move about, and 110cm where others must walk behind seated guests.
90cm behind each chair lets someone stand and step away; 110cm is the figure to use where guests need to squeeze past a seated diner. In practice, the extra 20cm is the difference between a polite shuffle and everyone standing up to let someone through.
You can bend these numbers safely in a few places:
- On a side against a wall or hedge that nobody sits at, you need no chair clearance at all.
- Benches let you tighten the clearance on that side, because there are no chair legs to scrape back.
- Keep the full 110cm on any side that doubles as a walkway or sits by a door.
- Do not squeeze the clearance on the side facing the barbecue, where you will be carrying hot food.
To get the footprint, add the recommended clearance to each side that has seating. A 180cm table with chairs along both long sides is roughly 3.6m long and 2.7m deep once clearance is included, following the same source’s worked example.
What table size seats how many people?
This chart turns the rule into numbers. Seats in chairs follow the 60cm rule, and benches squeeze in a little more because shoulder room is shared. Footprints use the clearance guidance around the table.
| Table length | Seats in chairs | Seats with benches | Footprint with 90cm clearance |
|---|---|---|---|
| 120cm | 4 | 4–6 | 3.6m × 2.7m |
| 150cm | 4–6 | 6 | 180cm × 150cm |
| 180cm | 6 | six to eight | 3.6m × 2.7m |
| 200cm | 6 | six to eight | 200cm × 150cm |
| 240cm | six to eight | six to ten | 240cm × 150cm |
The 180cm row matches Seek & Ramble’s guidance: six in chairs, up to eight with benches. The other rows follow the dimensions and seating guidance in Seek & Ramble’s chart.
On a balcony or small courtyard, a compact table may be a good fit. If your usable area is only a few centimetres short of a footprint, drop to the next size down rather than cutting clearance. Compare each row with the figures you wrote down earlier.

Round, square or rectangular: which shape works best?
Shape changes how a table behaves in your space, and how easily you can add a seat.
- Round tables are the most sociable, because everyone faces everyone. They suit small terraces, but you cannot squeeze in an extra chair the way you can along a rectangle.
- Rectangular tables make the best use of long, narrow decks. You can scale seating by adding chairs or a bench along the long sides.
- Square and bistro sets are the compact choice for tight patios and sun traps, where two to four people want a coffee or a light lunch.
If you are torn, think about how you really eat outside. A couple who host the odd barbecue are usually better served by a rectangle that can grow, while a family tucked into a corner of the garden often loves the round table’s intimacy.
How high should an outdoor dining table be?
Height shapes comfort as much as length does. A few typical ranges, with the sort of set each belongs to:
- Traditional dining, about 75cm: the everyday choice for relaxed family meals.
- Counter or gathering height, roughly 86 to 91cm: for casual drinks and nibbles, with taller chairs or stools.
- Bar height, around 102 to 109cm: for compact patios where you want a stand-up social feel.
Dining chairs tuck under a table about 75cm high with room to spare, while taller sets need seat heights to match. Check that the seat-to-tabletop gap feels comfortable before you commit.
Height also affects your parasol. A taller table needs a pole long enough to clear heads, and serving from a bar-height table is easier on the back for the host than for the diner reaching down.
Should you choose an extendable or fixed table?
A fixed table sized to your usual numbers is simpler and sturdier. An extendable table earns its place only if you host big gatherings a few times a year, and even then a couple of spare folding chairs can do the job.
Leg and base position changes how many people sit comfortably. Pedestal or central-base tables remove the corner legs, so knees have freedom and you can seat more along a side. Four-legged tables need enough gap between legs for chairs to slide in.
Before you buy, run through this:
- Measure the table closed and fully extended.
- Check how far the legs sit in from each corner.
- Note where the central support falls and whether it blocks a seat.
- Add 90cm clearance to the extended length, not the closed one.
Pro Tip: Tape out the extended footprint once, even if you will rarely use it, so you know it will not hit the door or the barbecue.
How do you lay out a set without blocking doors and walkways?
Start by mapping your traffic zones: the route to the back door, the path to the shed and the way to the barbecue. A set can fit on paper and still block the way people actually walk, so reserve the extra clearance on your busiest route first.
Here are layouts that tend to work:
- Balcony: a bench against the wall with a narrow table, or a small round table in the corner.
- Courtyard: a 180cm table set centrally, with chairs on all sides if there is room.
- Open lawn: a 180 to 240cm table with chairs all round, since nothing is in the way.
- Door and barbecue sides: keep these generous, and check door swings before you decide.
Tape the footprint on the floor and walk through it as if the family were already seated. For more arrangements, see our guide to arranging patio furniture. If you want visual ideas, The Plant Seed shows a range of garden and outdoor furniture in different set types.
How much space does each chair, bench and cushion need?
The 60cm-per-person rule is your starting point, but real chairs vary. Seat widths and cushion sizes differ from product to product: the SEATEC specification lists cushion widths of 40cm, 43cm and 46cm, which shows how a few centimetres per seat add up across a table.
- Chairs with arms need more width than armless ones, so measure the widest point.
- Cushions add depth when you sit and can push a chair further from the table, so measure with them on. Our guide to garden furniture materials explains how cushion choices change the feel and footprint of a set.
- Benches can seat more people because shoulder room is shared, but each person still needs about 60cm.
Multiply the width of one chair, arms and cushions included, by the number of seats on a side and compare it with the table length.
What is the final measuring checklist?
Take this outside with a tape measure.
- Measure the usable width and depth of your area.
- Mark door swings and obstacles with masking tape.
- Pick a table anchor size from the chart.
- Add the recommended clearance for each seated side.
- Tape out the full footprint and walk around it.
Worksheet fields: measured width × depth, chosen table size, seats required, shape, leg type and notes. As a final check, make sure the main walkway side has the recommended clearance if people must pass behind seated guests.
What mistakes do we see when people measure?

The same slips come up again and again: forgetting the door swing, ignoring cushion thickness and undercounting clearance on the side where food is served. The fixes are simple. Tape the footprint, measure chair width with cushions on, and give service and door sides extra room.
I would rather you measure twice than keep a table you have to wrestle past every evening. When you order from us, delivery and returns information can help you understand your options, though a taped footprint saves the trip altogether.

FAQ
What size table is a 6 seater?
A 180cm table seats six in chairs, according to Seek & Ramble. With benches on the long sides, it can fit up to eight. Follow the source’s clearance guidance around it for comfortable movement.
What are the typical sizes of dining tables?
Outdoor dining tables commonly come in lengths from 120cm to 240cm. The shorter ones suit two to four people, while 180cm and above suit larger groups. Pick the size that leaves 90cm clear behind each chair.
Is 32 too high for a dining table?
If you mean a table that feels higher than traditional dining height, it may work with taller seats but feel high with standard chairs. Check the seat-to-tabletop gap before buying.
What is the average size of an outdoor rectangular table?
A 180cm rectangular table can be a useful all-rounder for family use. According to Seek & Ramble, it seats six in chairs and larger tables can suit bigger households.
