Choosing a dining table is not just about how many seats you need. Many people worry that the table will feel too cramped, that elbows will bump, or that the room will suddenly feel much smaller. This guide brings together practical dining table sizes based on real-world use.
The dimensions in this guide are not based on textbook numbers alone. They also reflect our experience making and delivering custom solid-wood tables for homes, condominiums and restaurants. In practice, tabletop size is only part of the picture — chair width, leg position and clearance around the table matter too.
Dining Table Size Guide (Width × Length)
If you are measuring your dining area now, use this table as a practical starting point:
| Seats | Space-saving size | Recommended size | More comfortable / more tabletop space |
|---|---|---|---|
| 4 seats | 70 × 120 cm | 80 × 130–140 cm | 85–90 × 150 cm |
| 6 seats | 80 × 150 cm | 85–90 × 160–180 cm | 90–100 × 200 cm |
| 8 seats | 85 × 180 cm | 90 × 200–220 cm | 100 × 240 cm |
| 10 seats | 90 × 240 cm | 95–100 × 260–280 cm | 100–110 × 300 cm |

*A quick note for single-slab Suar wood tables with a natural live edge: the width follows the natural shape of the slab, so it may vary by around 5–10 cm at different points along the tabletop.

3 things to consider before choosing a table
Most people start with the question, “How many seats do I need?” But three other factors are just as important if you want the table to feel comfortable in everyday use:
- Will people have enough elbow room? As a practical rule of thumb, allow about 60 cm per person along the edge of the table. If the spacing is tighter, elbows can start to feel crowded during meals.
- Chair size and shape: Armchairs are usually wider — often around 55–65 cm — so they need more space along the table. Slimmer dining chairs can fit much more efficiently.
- How much food do you place in the middle? If you often serve several shared dishes in the middle of the table, a width of around 85–90 cm or more is much more practical. It gives you room for serving dishes while still leaving enough space for each person’s plate.
What size should a 4-seat dining table be?
A 4-seat dining table is a popular choice for condominiums, townhouses and smaller households.
If the room is compact, 70 × 120 cm can work, although there will be less room for shared dishes in the middle. If you have a little more space, we recommend moving up to around 80 × 130–140 cm for a more comfortable everyday proportion.
4-seat size summary:
- Space-saving: 70 × 120 cm
- Recommended for everyday comfort: 80 × 140 cm
- For larger chairs / more tabletop space: 85–90 × 150 cm
What size should a 6-seat dining table be?
This is one of the most common dining-table sizes for family homes. A 6-seat table is usually arranged either with three chairs on each long side, or with two on each long side plus one at each end.
For most 6-seat tables, we recommend a tabletop length of around 160–180 cm. This range is usually easier to arrange comfortably, but you should also check the distance between the table legs and the width of your chairs, because two tables with the same overall length may not offer the same usable seating space.
6-seat size summary:
- Space-saving: 80 × 150 cm (best with compact chairs)
- Recommended for everyday comfort: 85–90 × 180 cm
- For a more spacious feel and more tabletop room: 90 × 200 cm
What size should an 8-seat dining table be?
For larger families or people who regularly entertain guests, an 8-seat dining table should generally be around 200 cm long or more.
For width, we generally recommend around 90–100 cm. A table that is roughly 2 metres long but only 75–80 cm wide can feel visually narrow and leaves less space in the centre for shared dishes.
8-seat size summary:
- Starting size: 85 × 180–200 cm
- Recommended for everyday comfort: 90 × 220 cm
- For a more generous table and extra serving space: 100 × 240 cm
What size should a 10-seat dining table be?
A 10-seat table is a large-format dining table suited to spacious dining rooms, hospitality spaces or meeting rooms. The tabletop length will usually fall in the 240–300 cm range.
If you choose a single-slab Suar wood table around 2.5–3 metres long, it can become a strong focal point in the room, with the natural grain running continuously across the full length of the slab.
10-seat size summary:
- Starting size: 90 × 240 cm
- Recommended for everyday comfort: 100 × 260–280 cm
- For a spacious room: 100–110 × 300 cm
Do not forget chair clearance and walking space
It is easy to measure the tabletop and assume it will fit, then realise later that there is not enough room to pull the chairs out comfortably.
- Chair clearance: Allow at least 80–90 cm from the edge of the table to the wall so a chair can be pulled out and used comfortably.
- Walking space: If the area behind the chairs is also a main walkway, around 100–120 cm of clearance is much more comfortable so people can pass behind someone who is seated.

Frequently asked questions
How long should a 4-seat dining table be to avoid feeling cramped?
For comfortable elbow room, we recommend around 130–140 cm in length. If the room is very compact, 120 cm can still work, but it is better paired with smaller dining chairs.
Can a 140 cm-long dining table really seat six people?
It can, but the seating will be quite tight. A common arrangement is two chairs on each long side plus one at each end. For everyday dining, 160–180 cm is noticeably more comfortable.
How much space should I leave behind dining chairs?
Allow at least 80–90 cm from the edge of the table to the wall so people can sit down, stand up and move around more comfortably.
