Dining table size guide Australia 2026 — cm chart for 4, 6 & 8 seats

Last updated: 2026-09-25 (Australia/Sydney) · Written and reviewed by the Darrah Opens team, Australian home & outdoor specialists.

Quick answer: Allow about 60 cm of table edge per person: roughly 120–150 cm long for 4 seats, 160–180 cm for 6 and 200–240 cm for 8, and leave at least 90 cm clearance behind every chair so people can sit down and walk past.

Wrong table size is the most common dining mistake — too big blocks walkways, too small crowds elbows. This centimetre-focused guide helps Australian homes pick 4-, 6-, and 8-seater sizes, shapes, and clearances, then links Active pieces from Dining.

1. Quick size chart (approx.)

Seats	Rectangular length	Round diameter
2–4	120–140 cm	90–110 cm
6	160–180 cm	120–135 cm
8	200–220 cm	150 cm+

Allow ~60 cm table width per person along each long side.

2. Measure the room the Aussie way

Tape the table footprint and chair pull-out. Keep paths to kitchen, bifolds, and hallway clear. In open-plan spaces, align the table with the island run so serving is one step, not a weave.

3. Shape and extendable tables

Rectangular = max seats per wall. Round = softer flow. Extendable frames solve weeknight vs Christmas without dominating a small dining zone year-round.

4. Chairs, benches and clearance

Bench on one side packs kids; armchairs need extra width. Maintain 80–90 cm behind seats. For living-room seating instead, see the sofa buying guide. Outdoor dining sizes: outdoor dining setting guide.

Worked example: fitting a table into a typical Australian dining space

Say your dining area is 3.4 m × 3.0 m. Subtract 90 cm of clearance on each side where chairs will pull out: 3.4 − 1.8 = 1.6 m and 3.0 − 1.8 = 1.2 m. That leaves room for a table about 160 × 90 cm, which seats six comfortably. If one side runs against a wall with a bench seat, you can take back about 30 cm on that side.

Measure to skirting boards, not the middle of the room.
Allow for doors, sliding doors and heater vents that open into the space.
Tape the table footprint on the floor for a day before you order.

Frequently asked questions (2026)

What size dining table for 4 people?

Aim for about 120–140 cm long (rectangular) or ~90–110 cm diameter (round), with 60 cm width per diner. Leave 80–90 cm clearance behind chairs.

What size dining table for 6 people?

Typically 160–180 cm long. Extendable tables that sit at 140 cm daily and stretch for guests are popular in Aussie homes.

How much space around a dining table?

Plan 80–90 cm from table edge to wall or other furniture so chairs pull out and people walk behind. Islands and buffets need their own clearance.

Round or rectangular for small apartments?

Round tables ease traffic in square rooms and have no sharp corners. Rectangular tables seat more against a wall and suit open-plan runs.

Should seat height match table height?

Yes. Most dining tables are ~75 cm high; chairs ~45–50 cm seat height. Counter stools need a taller bench (~90 cm).

What size dining table for 8 people?

Look for about 200–240 cm long and at least 100 cm wide for a rectangle, or an extendable table that opens to that size for guests.

Is an extendable dining table worth it?

If you entertain a few times a year, yes. An extendable table lets you keep a 4–6 seat footprint every day and open it up for larger groups.
