The Dining Room: Proportion and Space Planning

The dining room is one of the most considered spaces in a home to get right — because it asks more of its furniture than most rooms do. A dining table needs to seat the right number of people comfortably, leave enough room to move around it, sit at the right height for the chairs you've chosen, and work within the proportions of the room itself. None of these things are difficult to get right, but they require thinking through in advance.

What follows is a practical guide to the key measurements and principles that make a dining room work — not as a set of rigid rules, but as a framework for making decisions that you won't need to revisit.

Table size and room proportion

The most common mistake in dining room planning is choosing a table that's too large for the room. A table that fits ten in a room that comfortably holds six will dominate the space and make it uncomfortable to use. The general rule: allow at least 90cm between the edge of the table and the nearest wall or obstacle. This gives enough room for someone to sit at the table while another person passes comfortably behind them.

In a room that's 4m x 3.5m, for example, a table of approximately 180cm x 90cm would work well — leaving adequate circulation space on all sides. In a smaller room, a round table often works better than a rectangular one, because the corners of a rectangular table can create tight spots that a round table avoids.

Seating allowance per person

Each person at a dining table needs approximately 60–65cm of width to sit comfortably — enough to eat without their elbows colliding with their neighbours. On the ends of a rectangular table, slightly more space is needed because the chair typically protrudes further into the room.

A 180cm rectangular table will comfortably seat 6: two on each long side and one on each end. Stretching it to 8 is possible but slightly tight. A 220cm table seats 8 comfortably, with room for 10 at a push. Round tables work on a similar basis: a 120cm round table seats 4, a 150cm seats 6, and a 180cm diameter table can accommodate 8 if the chairs are relatively slim.

Chair height and table clearance

Standard dining table height is 75–77cm. Standard dining chair seat height is 44–47cm. This gives a clearance of around 28–32cm between the seat and the underside of the table — enough for most people to sit comfortably with their thighs free.

If you're mixing chairs and benches, check the seat height of each. Some benches sit lower than standard chair height, which can affect comfort over a long meal. Similarly, chairs with arms need to fit beneath the table apron — measure the height of the apron (the structural piece beneath the tabletop) before choosing armchairs for a dining space.

Chair quantity and configuration

The number of chairs you need depends on how you use the space. If you regularly host and want to seat 8, buy 8 chairs — or 6 plus a bench on one side if the space is tight. If the table is primarily for 4 with occasional larger gatherings, 4 chairs plus 2 stored elsewhere works well and keeps the room from feeling crowded day to day. Browse our dining chairs to find options that work as matching sets or as complementary pairings.

Mixing chair styles is increasingly common — a host chair with arms at the ends of the table and side chairs along the length, for example — and can work very well if the materials and proportions are considered together rather than chosen separately.

Lighting over the table

Pendant lighting positioned over the dining table changes the quality of a meal significantly. The light should hang at roughly 70–80cm above the tabletop — low enough to create intimacy and direct light onto the table without being in anyone's eyeline. A single large pendant or a cluster of smaller ones both work. The key is that the light source is positioned to illuminate the table and the people around it, not the ceiling. Our lighting collection includes floor and table lamps that layer well with overhead lighting to build the right atmosphere for a dining space.

Getting these proportions right before you buy — measuring the room, working out the table size, thinking about how many chairs you actually need — takes an hour and saves years of compromise. It's worth doing carefully.
