Start a small restaurant layout with space per seat: about 12–15 sq ft (1.1–1.4 m²) per guest for full service and 18–20 sq ft (1.7–1.9 m²) for fine dining, aisles included. Full-service restaurants often give about 60% of the floor to the dining room and 40% to the kitchen and storage, while quick-service places reverse it to roughly 45% seating and 55% kitchen. Then plan aisles of 90–120 cm (36–48 in) and separate customer and staff routes.
Key takeaways
- Toast's benchmarks: about 18–20 sq ft per guest for fine dining and 12–15 sq ft for full service; banquet seating can go down to about 10.
- The classic split is 60% dining and 40% kitchen; quick service flips it to about 45% seating and 55% kitchen and storage.
- Keep main aisles about 120 cm (48 in) wide and secondary aisles at least 90 cm (36 in).
- In the US, the ADA Standards require at least 5% of dining surfaces to be accessible, with tops 28–34 in (71–86 cm) high.
- Customer, staff, delivery and waste routes should cross as little as possible.
Step 1: decide the format and the seat count
The format sets almost every number that follows. Toast's restaurant square footage guide gives about 18–20 sq ft per guest for fine dining and 12–15 sq ft for full service, with an average of about 15 sq ft per person; these figures already include aisles, wait stations and circulation.
| Format | Per seat (imperial) | Per seat (metric) | Seats in 50 m² of dining area |
|---|---|---|---|
| Fine dining | 18–20 sq ft | 1.7–1.9 m² | About 26–30 |
| Full service / casual | 12–15 sq ft | 1.1–1.4 m² | About 36–45 |
| Fast food / quick service | About 11–14 sq ft | About 1.0–1.3 m² | About 38–50 |
| Banquet | About 10 sq ft | About 0.9 m² | About 55 |
Step 2: split the kitchen and the dining room
Toast describes the traditional full-service split as about 60% front of house and 40% kitchen, prep and storage, and notes that quick-service restaurants reverse it to roughly 45% seating and 55% kitchen and storage. Another rule of thumb from the same guide is about 5 sq ft (0.5 m²) of kitchen per dining seat.
- Fast food: a straight kitchen line from storage to prep to cooking to the pass, with the counter directly in front of it.
- Casual restaurant: a kitchen at the back, a pass with a pick-up window and service stations close to the tables.
- Café: a coffee bar and display at the front, a small prep kitchen behind and plenty of small tables.
Step 3: aisles, tables and counters
| Item | Typical size |
|---|---|
| Main service aisle | About 120 cm (48 in) |
| Secondary aisle | At least 90 cm (36 in) |
| Table for two | 60–75 cm (24–30 in) square |
| Table for four | 75–90 cm (30–36 in) square or 120 × 75 cm (48 × 30 in) |
| Booth seat depth | 45–50 cm (18–20 in) |
| Bar counter height / stool spacing | About 105–110 cm (42 in) / 60 cm (2 ft) per stool |
| Queue lane at a counter | 90–120 cm (36–48 in) |
In the US, the 2010 ADA Standards require at least 5% of the seating at dining surfaces to be accessible, and chapter 9 of the standards sets those tops at 28–34 in (71–86 cm) above the floor with knee clearance below. Many other countries have similar accessibility rules.
Step 4: plan the flows
- Customers Entrance, queue or host stand, order point, tables, toilets and exit. Keep the queue away from the door and from seated guests.
- Service Short, direct routes from the pass to every table, with service stations for cutlery and water so staff do not walk back to the kitchen for everything.
- Kitchen Deliveries in, cold and dry storage, prep, cooking, pass. Raw and ready-to-eat food should not cross.
- Dirty dishes and waste A separate return to the wash-up area and a route for waste that does not go through the dining room.
Draw it and count the seats
In ArchHomeAI, open the fast-food, restaurant or café space, enter the unit's dimensions and place the counter, kitchen line and tables at real size. You can compare a layout with more two-tops against one with booths, check aisle widths and share renders and the plan with partners or the landlord.

Frequently asked questions
How many seats fit in a small restaurant?
Divide the dining area by the space per seat for your format: about 1.1–1.4 m² (12–15 sq ft) for casual full service. A 50 m² dining room seats roughly 36–45 people, but the legal maximum depends on local fire and occupancy codes.
How big should the kitchen be?
In a full-service restaurant about 40% of the total area is a common starting point; quick-service kitchens and storage often take more than half. Toast also suggests about 5 sq ft of kitchen per dining seat.
How wide should restaurant aisles be?
Plan main service aisles of about 120 cm (48 in) and secondary aisles of at least 90 cm (36 in). Accessible routes in the US need at least 36 in (91 cm) clear.
Does the planner check food-safety or fire rules?
No. It helps you draw and compare layouts at real size. Food-safety, fire, ventilation and accessibility rules depend on your location and must be checked with the authorities and qualified professionals.
