Garden Table Dimensions UK: Seating Chart & Parasol Hole Standards

A garden table is sized by the length of its perimeter, not by the area of its top. Seating capacity follows from how much edge each person needs, and the figure that governs almost every outdoor dining decision is a place setting width of around 60 cm (about 24 in). Once that is fixed, the seating chart writes itself for every table shape.

The parasol question has a similarly simple answer. Most garden tables that include a central aperture are drilled to accept a pole in the region of 38 mm to 50 mm in diameter, and the aperture is usually supplied with a reducer ring or cap so more than one pole size can be used. Matching the pole to the hole, and the base to the pole, is the part that gets overlooked.

Key findings at a glance

• Allow around 60 cm (about 24 in) of table edge per diner as the working place setting width.
• Table width of around 80 cm to 90 cm (about 31 in to 35 in) allows two people to sit opposite each other with a shared central run for dishes.
• Round tables seat by circumference, so a diameter increase adds capacity more slowly than a length increase on a rectangular table.
• Central parasol apertures are commonly sized for poles in the 38 mm to 50 mm range, usually with a reducer supplied.
• A parasol used through a table still needs a weighted base beneath it: the table holds the pole upright but does not resist wind loading.
• Allow at least 90 cm (about 35 in) behind each chair for pulling out and standing up on a patio.
• Hard landscaping needs to be level: an uneven patio is the most common cause of a wobbling outdoor table and of parasol lean.

Seating capacity is edge arithmetic

Take the usable perimeter of the table and divide it by 60 cm. On a rectangular table, the two long sides carry most of the seating and the ends add one place each if the width allows it. A table that is too narrow at the ends will not take an end setting comfortably, which is why a nominal eight seater can behave like a six seater in practice.

Round tables are governed by circumference rather than diameter, and the relationship is not intuitive. Increasing the diameter adds capacity, but the gain per centimetre is smaller than most buyers expect, and a large round table pushes the centre out of reach. Where a household wants a big table for occasional use and a small footprint the rest of the time, an extending format is the better answer, and the same principle applies indoors across extending dining tables UK. Outdoors, we normally steer people towards rectangular formats in garden dining tables UK because British patios are more often long than square.

Parasol apertures and what they do not do

The central hole in a garden table is an alignment feature. It holds the pole vertical and stops it drifting, and it usually comes with a plastic reducer so a narrower pole can be used in a wider aperture. What it does not provide is resistance to wind. A parasol is a sail, and the force it generates in a gust is transferred down the pole into whatever is holding it. A table top is not designed to absorb that load.

The correct arrangement is a weighted base sitting on the ground beneath the table, with the pole passing through the table aperture and into the base. The table then guides the pole while the base resists the overturning force. Cantilever parasols do not use the table at all and rely entirely on their own base, which is why they need substantially more weight. Our garden parasols UK range lists pole diameters so the match can be checked before ordering.

British weather is a dimensional problem too

Outdoor furniture in the UK spends most of the year unused and exposed. That affects sizing decisions in ways indoor furniture does not. A table that needs to be moved under cover in October should be liftable by two people, which caps its practical size regardless of how much space the patio offers. Folding and extending outdoor tables exist largely to solve winter storage rather than summer seating.

Material determines the maintenance cycle rather than the dimensions. Timber needs periodic treatment and benefits from being raised off standing water. Powder coated aluminium and resin weaves tolerate wet conditions with little attention. Glass and stone tops are heavy and stable in wind but need clean, level support to avoid stress points. Where storage is limited, a lockable garden storage UK unit for cushions and parasol canopies extends the life of the soft components considerably.

Table height outdoors follows the same convention as indoors, with dining surfaces generally sitting around 74 cm to 76 cm (about 29 in to 30 in) above the ground. What changes is the ground itself. A patio laid with a fall for drainage means the table stands very slightly out of level by design, and on a long table that small slope is enough to make glasses drift. Where the fall runs across the width of the patio rather than along its length, orienting the table so the slope runs across the short dimension reduces the effect.

Seating chart by table size and shape

The table below converts standard outdoor table dimensions into realistic seating counts using a place setting width of 60 cm. Every figure is a physical dimension rather than a statistic.

Shape	Table size	Comfortable seats	Maximum at a squeeze
Round	90 cm (35 in) diameter	4	4
Round	120 cm (47 in) diameter	5	6
Round	150 cm (59 in) diameter	7	8
Rectangular	120 cm x 80 cm (47 in x 31 in)	4	6
Rectangular	150 cm x 90 cm (59 in x 35 in)	6	6
Rectangular	180 cm x 90 cm (71 in x 35 in)	6	8
Rectangular	220 cm x 100 cm (87 in x 39 in)	8	10
Square	90 cm x 90 cm (35 in x 35 in)	4	4

What this means for UK homes

Measure the patio before the table. The usable area is the table footprint plus at least 90 cm (about 35 in) on every side that will be used for seating, because a chair needs to slide back and a person needs to stand. On a typical rear patio, that clearance requirement rules out more tables than the table dimensions themselves do.

Check the surface. Patio slabs settle, decking boards move, and an outdoor table sitting across a level change will rock permanently. Adjustable feet help on small variations, but a genuinely uneven surface needs correcting rather than compensating for. This matters more with a parasol in place, because any lean in the table transfers straight to the pole.

Plan for the canopy rather than the table when choosing parasol size. A parasol should shade the seated diners, which means the canopy needs to overhang the table edge on the side facing the sun. Take the pole diameter, match it to the aperture, and confirm the base weight against the manufacturer guidance for that canopy size. Where the garden has a fixed seating area rather than a dining set, a coordinated garden seating sets UK arrangement usually makes better use of a small patio than a full dining table.

Methodology

This 2026 reference was compiled by our editorial team as a UK furniture retailer. It uses standard outdoor table dimensions, a conventional place setting width of 60 cm, standard circulation clearances for seated furniture, and the pole diameter ranges common to garden parasols and table apertures. Seating counts are derived arithmetically from perimeter and place setting width. No sales data, customer data, survey fieldwork or wind loading test results are included, and no percentages or market figures are stated anywhere in this report.

Frequently asked questions

What size garden table seats six?

A rectangular table of around 150 cm x 90 cm (59 in x 35 in) seats six comfortably. A round table needs roughly 140 cm to 150 cm (55 in to 59 in) in diameter for the same number.

What size is a standard parasol hole?

Table apertures are commonly sized for poles in the 38 mm to 50 mm range, and most tables are supplied with a reducer ring so a narrower pole can be centred.

Do I still need a parasol base if the table has a hole?

Yes. The table aligns the pole but does not resist wind. A weighted base on the ground beneath the table is required.

How much space do I need around a garden table?

Allow at least 90 cm (about 35 in) of clear ground on every seated side so chairs can be pulled back and people can stand up.

Should a garden table be stored over winter?

Timber and upholstered components benefit from cover or storage. Powder coated aluminium and resin weave frames tolerate exposure, though cushions and canopies should always be stored dry.
