How to Choose a Dining Table: Size, Shape & Material Guide (2026)

Allow 60–70cm of table length per person — so a 160cm table seats four to six comfortably, and a 200cm table seats six to eight. Leave at least 90cm between the table edge and any wall or furniture so chairs can be pushed back freely. Standard dining tables sit 74–76cm tall. Sintered stone suits families who want low maintenance; timber suits warmer, more natural interiors; extendable tables suit anyone who entertains occasionally but doesn't want a large table every day.

Dining tables are chosen badly more often than almost any other piece of furniture. People underestimate how much space they actually need, choose the wrong shape for their room, or pick a material that can't handle daily family use. Then they live with it for ten years.

This guide covers what actually matters — how to size a table for your room and your household, which shape works where, and which material suits your life — so you get it right the first time.

Step One: Work Out What Size Table You Need

The size of your table is determined by two things: how many people you need to seat, and how much room your space actually has for the table and chairs combined.

Seating Capacity — Allow 60–70cm Per Person

Each person at a dining table needs between 60cm and 70cm of table length to sit comfortably. 60cm is workable; 70cm is generous. If you regularly have guests, plan for the generous end.

Seating capacity quick guide:

These figures are for rectangular tables. Round tables seat fewer people per centimetre of diameter — a 120cm round table seats four, a 150cm round seats five to six.

The 90cm Clearance Rule

Once you have a table size in mind, check whether your room can actually fit it. The rule: allow at least 90cm between the edge of the table and any wall or furniture behind the chairs. This is the minimum clearance for chairs to be pushed back and for someone to walk behind a seated guest without squeezing past.

To test it: measure your room, subtract the table length, then divide the remainder equally on each side. If either side falls under 90cm, the table is too long for the space.

For a dining table in an open-plan space, the same clearance rule applies to where the dining zone ends and the living zone begins. Our open-plan living room styling guide covers how to zone these spaces properly.

Step Two: Standard Table Height and Chair Pairing

This is the dimension most people never check, and it's the one that makes dining uncomfortable if you get it wrong.

Standard dining tables sit between 74–76cm tall. Standard dining chair seat heights sit between 44–47cm. The gap between the seat and the underside of the table should be 28–32cm — enough to sit with relaxed legs, not so much that your arms are raised to reach the table.

Most dining tables at Marco sit at the standard 74–76cm range. If you're buying a kitchen island or bar bench, that's a different height category — check our bar stool guide for those measurements.

Step Three: Choose Your Shape

Table shape affects how many people you can seat, how the room feels, and how traffic moves around the table. The wrong shape for a room makes a space feel awkward even when the size is right.

Rectangular

The most practical shape for most homes. Rectangular tables seat more people per square metre of table than any other shape, suit long narrow rooms naturally, and give a clear sense of layout — there's a head of the table, two sides, clear flow in and out.

• Best for: families, regular entertaining, long or rectangular dining rooms
• Good examples at Marco: the Roma 6-seater in natural ash veneer, the Olmo Fiorito 8-seater in sintered stone, the Castello walnut veneer rounded rectangular table

Oval

An oval table has the length of a rectangle but with rounded ends, which makes it easier to move around and removes the hard corners that can catch hips and bags. It seats the same number as a rectangle of equivalent length but feels less formal.

• Best for: rooms where traffic moves around the ends of the table, open-plan homes, households that want a softer look
• The Palazzo 240cm walnut veneer oval and the Venus 200cm walnut veneer oval are both strong options — the Palazzo with a sculptural centre pedestal base, the Venus with a double cylindrical pedestal

Round

Round tables are more intimate — everyone faces everyone else, with no head of the table. They work particularly well in square rooms where a rectangle would feel off-axis, and in smaller dining areas where you want the table to feel less dominant.

• Best for: 2–4 person households, square rooms, breakfast nooks, apartments
• The Roma ash veneer round table and the Mont Blanc sintered stone round (in black) are the two most popular round options at Marco
• One thing to know: round tables don't extend. If you occasionally need to seat six or more, consider oval or rectangular instead

Extendable

An extendable table has a standard fixed size for everyday use and extends with one or two additional leaves when you need to seat more people. The trade-off is a visible seam when extended and slightly more maintenance on the extension mechanism over time.

• Best for: households that entertain occasionally but don't want a large table every day
• Check the extended length before buying — some tables extend by 40–50cm (one extra seat per side), others extend further
• The Forma Bella sintered stone extendable dining table is a good option for households that want the practicality of sintered stone with the flexibility of an extendable format

Step Four: Choose the Right Material

The material of your dining table determines how it ages, how much maintenance it needs, and how forgiving it is in daily use. A dining table has hot plates, wet glasses, kids doing homework and guests resting elbows on it — the material needs to be honest about that.

Our take:

Sintered stone is the most popular material in our Fyshwick showroom for families and everyday dining — it handles heat from plates, doesn't stain from wine or sauces, and never needs sealing. Walnut veneer is the choice when warmth matters more than bulletproof practicality. If you're after something more dramatic, the Aurora Black Rose marble top dining table is a genuine statement piece, though it needs more care than stone or timber.

Step Five: Pair It With the Right Chairs

A dining table and chairs are bought together but often chosen separately, and the mismatch shows. A few things that actually matter:

Chair Seat Height

Your chairs need to work with your table height — see the table in Step Two. Most standard dining chairs at 44–47cm seat height suit a 74–76cm table. Check before buying if mixing chairs from different sources.

How Many Chairs

Seat your realistic number, not your maximum. A table that seats eight with six chairs leaves two gaps that feel deliberate. A table that seats six with six chairs feels considered. Buy chairs for how you use the table most days, not how you'd use it at Christmas.

Matching vs Mixing

Matching chairs across all seats gives a clean, cohesive look. Mixing works when you share a common element — same leg finish, same seat height, similar scale. The most common mix: upholstered chairs on the sides, a timber or metal chair at the heads.

For a full breakdown of chair seat heights, fabrics, back styles and how to mix them, our dining chairs guide covers it all in detail.

Dining Table Styles by Interior Look

The same table can suit different rooms depending on what you pair it with, but some combinations work consistently better than others.

Japandi

Low visual noise. Walnut or ash veneer table, upholstered dining chairs in boucle or natural linen, no pattern mixing. The Castello walnut veneer rounded rectangular table or the Venus 200cm oval work well here — both have clean lines and warm timber grain without being ornate.

Hamptons

Lighter timbers, white or rattan elements, relaxed but polished. An ash veneer or white-finish table, upholstered chairs in a performance fabric or linen, a pendant light above. The Roma ash veneer rectangular table is a natural fit.

Contemporary / High-End

Sintered stone top with a metal base is the clearest expression of this look. The Filo Dorato sintered stone top dining table and the Vittoria sintered stone table with brushed gold stainless steel frame both suit contemporary interiors that want a material moment without going full marble.

Statement / Glam

The Aurora Black Rose marble top dining table is the choice here. Genuine marble, unique veining, paired with velvet or leather chairs. It needs more care than sintered stone but nothing else in the range makes quite the same impression.

One More Thing: Rugs Under the Table

A rug under the dining table anchors the space and defines the zone, particularly in open-plan rooms. The rule: the rug needs to be large enough that all four chair legs sit on the rug even when the chairs are pushed back. A rug that's too small looks like an afterthought and creates a trip hazard when chairs straddle the edge.

For a 160cm table, you need at least a 200×300cm rug. For a 200cm table, 240×340cm or larger. Browse our rug range for sizing options — the product pages include a room size guide.

A Quick Checklist Before You Buy

• Measure your room — then subtract the table size and check 90cm clearance on all sides
• Count your realistic daily seats, not your Christmas maximum
• Check table height (74–76cm standard) against your chair seat height
• Choose shape based on your room proportions — rectangular for long rooms, round or oval for square rooms
• Choose material based on how you actually use the table — sintered stone for families, timber for warmer aesthetics
• If buying extendable, check both the closed and extended dimensions
• Size your rug so chair legs stay on it even when pushed back

Frequently Asked Questions

What size dining table do I need for 6 people?

A 160–180cm rectangular table seats six comfortably, allowing 60–70cm per person. If you entertain often, go to 180cm or consider an extendable table that reaches 200cm+ when you need it.

How much space do I need around a dining table?

Allow at least 90cm between the table edge and any wall or furniture behind the chairs. This gives enough room for chairs to be pushed back and for people to walk behind seated guests without squeezing.

What is the standard height of a dining table?

Standard dining tables sit between 74–76cm tall. This pairs with dining chairs at 44–47cm seat height, giving the recommended 28–32cm gap between the seat and the underside of the table.

Is sintered stone better than timber for a dining table?

Sintered stone is more practical for busy households — it resists heat, stains and scratches without sealing or oiling. Timber is warmer in appearance and better suited to natural, Japandi or Hamptons interiors, but needs occasional maintenance to stay in good condition.

Should I get a round or rectangular dining table?

Rectangular tables suit most rooms and are the most practical for seating larger groups. Round tables work well in smaller square rooms and create a more intimate setting — everyone faces each other with no head of the table.
