What size dining table do I need?

Allow about 60cm of table width per person and leave at least 90–100cm of clearance to the walls and furniture so chairs can pull out. Size to the room first, then to the number of seats you realistically need day to day.

Rectangular tables seat the most and suit long or open-plan rooms. Round tables are sociable, corner-free and great for small or square rooms. Square tables suit compact square rooms, and extendable tables flex between everyday and entertaining.

Timber, marble or glass top?

Solid timber is warm, durable and re-sandable with occasional care. Marble is a hard-wearing statement but needs sealing to resist stains. Glass feels light but shows marks. Laminate and engineered tops are the most affordable and the easiest to care for.

A dining table is where the household gathers, so it needs to seat everyone comfortably, fit the room with space to move, and stand up to daily life. The right table is a balance of size, shape and a top material that suits how you live. This guide covers how to size a table to your room and the number of seats, how shape changes the feel and capacity, how the common top materials compare, and how to match chairs.

Things to consider before you choose

Plain practical advice for Australian builds. No fluff.

Size it to the room and the seats

Allow about 60cm of table width per person, and leave at least 90–100cm clearance between the table edge and the walls or furniture so chairs can pull out and people can walk past. Measure the room before you fall in love with a table.

Choose the shape for the space

Rectangular tables suit long or open-plan rooms and seat the most. Round tables feel sociable, have no sharp corners and work well in smaller or square rooms. Square tables suit compact square rooms. Extendable tables flex from everyday to dinner-party.

Pick a top material you can live with

Solid timber is warm, durable and can be re-sanded but needs occasional care. Marble is a statement and very hard-wearing but can stain without sealing. Glass feels light and airy but shows marks. Laminate and engineered tops are the most affordable and easy-care.

Don't forget the chairs and the base

Check seat height against the table (around 28–30cm between seat and tabletop), and whether a pedestal or trestle base gives more legroom than four corner legs. Buy chairs and table together where you can so the proportions match.

How much does it cost in Australia?

Dining table prices depend on size, base and top material: a compact laminate or engineered-top table is the affordable end, solid timber sits in the middle to upper range, and large marble tables are the top. Dining chairs are usually priced separately, so budget for the set. Compare live prices for the size, shape and material you want directly at the retailer.

Common mistakes to avoid

Buying a table too big for the room, leaving no chair clearance
Forgetting the 90–100cm walking space around the table
Choosing marble or glass without considering staining and marks
Mismatching chair height to the tabletop
Pricing the table but forgetting the chairs
