How many guests a restaurant or café can host comfortably depends largely on its tables and chairs. The figures below are approximate starting points widely used in the industry; adapt them to the shape of the room, the service style and the products you choose.
Table edge per guest
A common starting point is about 60 cm of table edge per guest, so two people sitting side by side can eat without bumping elbows.
- For 2: 60–75 cm square tables are common in cafés.
- For 4: 75–90 cm square or round tables are preferred.
- For 6: Rectangular tables of around 140 cm seat three on each long side. Siesta's Air Table 140, for example, measures 140×80 cm.
Table and seat height
Dining tables are usually 72–75 cm high. A difference of about 27–30 cm between seat height and table height gives a comfortable posture.
Examples from our site: the Air chair has a 44 cm seat height, Diva 46 cm and Louise 45 cm; the Air Table 140 is 74 cm high and Cast Garden's Q75 Round Table 71 cm. Dimensions are listed on every product page.
Aisles and service routes
- Between a chair back and the next table: Leave enough room for guests to stand up and sit down easily.
- Service routes: Plan the main lines waiters use with trays more generously.
- Entrance, till and restroom routes: Keep them separate so they don't block at busy times.
Exact clearances can depend on fire and accessibility rules, so we recommend finalising the plan with your architect.
Tips for a flexible layout
- Square tables can be joined into long tables for larger groups.
- Stackable chairs make it easy to clear extra seats when the layout changes.
- Using the same model on the terrace and indoors lets you move chairs between them as seasons change.
