Standard restaurant chair dimensions
Getting restaurant chair dimensions right affects both guest comfort and how many covers you can fit into the room. Most dining tables stand 72–76 cm high, so the matching chair should have a seat height of 44–47 cm. That leaves 27–30 cm between the seat and the tabletop, which gives enough room for the thighs and lets elbows rest on the table at a natural angle.
For a standard side chair, aim for a seat width of 42–48 cm and a seat depth of 40–46 cm. Deeper seats feel better during long dinners, but they push the chair further from the table and eat into aisle space. Overall back height is typically 80–90 cm from the floor; very tall backs can make a busy dining room look cluttered.

| Measurement | Recommended value |
|---|---|
| Table height | 72–76 cm |
| Seat height | 44–47 cm |
| Seat to tabletop gap | 27–30 cm |
| Seat width (side chair) | 42–48 cm |
| Overall armchair width | 55–62 cm |
| Table edge per diner | 60 cm (65–70 cm with armchairs) |
| Table edge to wall | at least 75 cm |
| Between tables, guests back to back | 135–150 cm |
| Main service aisle | 120–150 cm |
| Secondary aisle | at least 90 cm |
Clearance between tables and chairs
A seated guest needs roughly 45–60 cm behind the table edge to push the chair back and stand up. Allow at least 75 cm from the table edge to a wall, column or other fixed obstacle. When guests at two neighbouring tables sit back to back, leave 135–150 cm between the table edges, or about 180 cm if staff also need to walk between them.
Common table sizes are 70×70 cm for two people, 80×80 to 90×90 cm for a square four-top, and 90–100 cm in diameter for a round table of four. As a baseline, give every diner 60 cm of table edge.
Aisle widths and space per diner
Main service aisles running from the kitchen should be 120–150 cm wide. Secondary aisles between tables should be no narrower than 90 cm, which is also the practical minimum for wheelchair users. The floor area you need per seat depends on the concept:
- Fine dining: 1.7–1.9 m² per guest
- Casual restaurants and cafés: 1.2–1.5 m²
- Quick service and self-service: 1.0–1.2 m²
These figures cover tables, chairs and circulation only, not the kitchen, bar or restrooms. As a rule of thumb, a café with 100 m² of net dining area can seat about 65–80 guests.
Side chairs or armchairs?
Side chairs take up less space, slide fully under the table and maximise capacity at peak times. Restaurant armchairs offer more support during long meals and give fine-dining rooms a more premium feel. If you choose armchairs, check two things:
- The armrests must clear the table apron, otherwise the chair cannot be pulled in. Leave at least 2–3 cm between the top of the arm and the underside of the apron.
- Increase the table edge per diner to 65–70 cm, or neighbouring guests will knock elbows.
Many operators mix both types: side chairs on the main floor and armchairs in corners, window seats or private areas.
Checklist before you order
- Measure your table height and keep a 27–30 cm gap between seat and tabletop.
- Check the table base: a central pedestal frees up more legroom than four corner legs.
- Decide whether you need stackable chairs for cleaning and events.
- Specify floor glides that suit your flooring.

Common questions
What is the standard seat height for a restaurant chair?
For standard tables of 72–76 cm, the seat height should be 44–47 cm. A 27–30 cm gap between the seat and the tabletop is the most comfortable.
How much space should there be between restaurant tables?
Leave 135–150 cm between tables where guests sit back to back, or about 180 cm if staff pass between them. Keep at least 75 cm from the table edge to any wall.
How many square metres per person does a restaurant need?
Plan 1.7–1.9 m² per guest for fine dining, 1.2–1.5 m² for casual restaurants and cafés, and 1.0–1.2 m² for quick service. These figures exclude the kitchen, bar and restrooms.
