Restaurant floor plan: layout, seating and code basics

A restaurant floor plan is a scaled drawing of your space: dining room, bar, host stand, restrooms, kitchen and storage, and the paths guests, servers and plates take between them. A good one fits as many seats as the room can comfortably hold, lets staff work a Friday rush without colliding, and gets through the building, fire, accessibility and health reviews before you open.

The starting numbers, in US figures: roughly 60% of the space for the front of house and 40% for the kitchen and back of house, about 12–15 square feet per seat in a full-service dining room and 18–20 in fine dining, a 36-inch accessible route, and at least 5% of dining seats built to the ADA’s accessible-table rules. Once a room holds more than 49 people, the building code generally wants a second exit.

Those are starting points, not approvals. Your building department, fire marshal and health department decide what your room can hold, under the code edition your city or state has adopted. This guide is general information, not architectural or legal advice, and Platevio does not review, stamp or certify plans.

Split the space: front of house and back of house

The front of house is everything guests use: dining room, bar, entry and waiting area, host stand or ordering counter, restrooms. The back of house is the rest: kitchen, prep, dish, storage, receiving, office and staff area.

The common rule of thumb is about 60% for the dining room and 40% for the kitchen. Move away from it for a reason:

• A scratch kitchen with a long menu needs more prep, storage and refrigeration, so the back of house grows past 40%.
• A café or counter-service spot that assembles more than it cooks can give more to the front. But the counter, espresso machine and queue live there too, so less of it becomes seating.
• A bar-led venue puts a working station (ice, glass washer, back bar) in the middle of the front of house.

Before dividing anything, find what is expensive to move: the hood, gas line, floor drains, grease interceptor and existing restrooms. The kitchen usually goes where those already are.

Then work out your real dining floor. Say you lease 2,500 sq ft. A 60/40 split gives 1,500 sq ft of front of house. Take off 200 for restrooms, 100 for the entry and host stand and 250 for the bar, and 950 sq ft is left for tables. That is the number you divide by square feet per seat.

How many seats fit: square feet per seat and table mix

Per-seat figures measure the dining floor only, and published ranges vary:

No trade source publishes a separate café figure. A café with stools and small tables plans near the quick-service end; one with table service, nearer casual.

The formula: seats ≈ dining floor sq ft ÷ sq ft per seat. The 950 sq ft above at 14 sq ft per seat gives about 68 seats. Check that against the occupant load (below) before ordering chairs: a plan at 12 sq ft per seat can hold more chairs than the code’s table-and-chair factor allows for.

Table sizes

Common commercial sizes, per Superior Seating:

2-tops, 4-tops and combinable tables

The classic mistake is a room of four-tops. A couple at a four-top leaves two chairs empty all night. Look at how people actually arrive: over two busy weeks, divide covers by tables served. If your average party is close to two, lean toward two-tops. Then build in flexibility:

• Square two-tops along walls and banquettes push together into a four or a six, then split again.
• Match heights and bases so joined tables sit flat.
• Keep a few fixed four-tops near the entrance for families and high chairs.
• Use rounds sparingly. They seat groups well but don’t combine.

Aisles, circulation and ADA accessibility

Spacing guidelines (industry practice)

Sources: WebstaurantStore for chairs, Superior Seating for tables and aisles.

What the fire and building codes say

• NFPA 101, the Life Safety Code (2018, section 12.2.5.8), requires aisles serving seating at tables to be 44 inches wide where they serve more than 50 occupants, 36 inches where they serve 50 or fewer.
• The International Building Code (2021, section 1030.13.1) measures aisle width from a line 19 inches out from the table edge, where an occupied chair sits. The aisle accessway between tables needs at least 12 inches, plus half an inch per foot beyond 12 feet of length, and travel along it can’t exceed 30 feet before a guest has a choice of two ways out.

In plain terms: draw every chair as if someone is sitting in it, then measure the aisle from there.

ADA requirements for dining areas

New construction and alterations follow the 2010 ADA Standards for Accessible Design. The parts that shape a dining room:

1. Every dining area must be reachable. Section 206.2.5 requires an accessible route to all dining areas, including raised or sunken areas and outdoor dining, with narrow exceptions for some mezzanines and for existing raised areas in alterations.
2. The route is 36 inches clear, narrowing to 32 inches for no more than 24 inches (a doorway). Turning around an obstruction, such as the end of a banquette, needs 48 inches at the turn and 42 approaching it.
3. At least 5% of seats must be accessible, spread through the room. Section 226.1 covers 5% of the seating and standing spaces at dining surfaces; 226.2 requires them to be dispersed, not bunched by the door.
4. Accessible tables are 28–34 inches high (section 902), with a 30” × 48” clear floor space for a forward approach and knee clearance at least 27 inches high and 30 inches wide, toe space reaching at least 17 inches under. A table base where footrests go can defeat that, so check bases before you buy.
5. Bars count. The advisory to 902.1 lists bars as dining surfaces. A standard 40–42” bar top is above the 34” maximum, so plan a lowered section or accessible seating in the bar area, and confirm with your architect how your jurisdiction applies the rule.
6. Counters where guests order or pay need a stretch at most 36 inches high: 36 inches long for a side approach, or 30 inches long with knee space for a forward approach (904.4).

Existing businesses not altering anything still must remove barriers where that is “readily achievable”: easy to do without much difficulty or expense.

Occupant load, exits and restrooms

Occupant load

Occupant load is the number of people the code assumes your space holds. Exits, door hardware and restroom counts are sized from it. It is floor area divided by a factor from IBC Table 1004.5, shown here from Washington’s adopted code:

NFPA 101 uses the same 15 net for dining tables and 7 net for concentrated use. “Net” means subtracting space nobody can stand in: the bar itself, washrooms, storage, columns. Fixed seating counts by its seats.

Example: a 1,000 net sq ft dining room ÷ 15 = 67. A 150 sq ft standing area by the bar ÷ 5 = 30. An 800 sq ft kitchen ÷ 200 = 4. Occupant load: 101.

As the Illinois State Fire Marshal notes, the calculated load sets the minimum exit capacity, not automatically the maximum. Your posted capacity is what your fire marshal approves.

Exits

• Under IBC Table 1006.2.1, an assembly space such as a restaurant needs two exits once it exceeds 49 occupants or a 75-foot common path of travel, separated by at least half the room’s longest diagonal.
• Doors serving 50 or more people must swing in the direction of exit travel, under both the IBC and NFPA 101.
• A latching door in an assembly space needs panic hardware once it serves 50 or more people under the IBC, or 100 or more under NFPA 101. Your jurisdiction’s adopted code decides which applies.
• NFPA 101 also requires the main entrance to handle half the occupant load.

Don’t assume a back door reached through the kitchen counts as your second exit. Ask the plan reviewer first.

Restrooms

Fixture counts come from the same occupant load. The model table for restaurants, as adopted in Montana, calls for one water closet per 75 men and one per 75 women, one lavatory per 200, one drinking fountain per 500 and one service sink. States add rules; Montana requires at least one urinal in food service. An accessible toilet room needs a 60-inch turning circle or T-shaped turning space.

The health department reviews your plan too. The FDA Food Code, as adopted by states such as Delaware (section 8-201.11), requires plans to be approved before a food establishment is built, converted or, where the regulator asks, remodeled.

Kitchen layouts and workflow

A good kitchen moves food one way: receiving, storage, prep, cooking, the pass, the dining room. Dirty plates come back to dish without crossing the hot line. The main layouts, as WebstaurantStore describes them:

One architect’s rule of thumb: in a commercial kitchen, 48 inches is really a minimum and 72 is comfortable where work surfaces face each other.

Put the pass where servers collect plates without stepping into the line, with the kitchen screen or ticket printer facing whoever calls orders. Put the dish drop just inside the kitchen door, so dirty plates never travel past clean ones.

Placing the bar, host stand, restrooms and service stations

Host stand or ordering counter. Just inside the entrance, with a view of the room, but out of the door swing and the exit path, with space for a few waiting guests. In a café, run the queue along a wall rather than across the door or into the seating, and keep pickup apart from ordering.

Bar. Near the entrance, it catches walk-ins and gives waiting guests somewhere to go. At the back, it pulls people through the room. It needs plumbing, drains and ice, so it rarely goes wherever looks best. Put the servers’ pickup well at the end nearest the dining room, not between stools.

Restrooms. Guests should reach them on the accessible route without passing through the kitchen or crossing the servers’ main lane. Avoid a restroom door opening straight onto a table.

Service stations. One per section, stocked with water, cutlery, napkins and a device for orders, so servers don’t cross the room for a fork. Tuck them into alcoves off the main aisle. The table nobody wants, by the kitchen door or the restroom, is often the best spot for one.

Two sample layouts: a 1,500 sq ft café and a 3,000 sq ft restaurant

Both are illustrative only: not to scale, not code-reviewed, not a substitute for a designer’s drawings.

A 1,500 sq ft café

Seats: 8 two-tops (16), 3 four-tops (12) and a 12-foot window counter at 24 inches per stool (6) make 34. Five percent of 34 is 1.7, so plan at least two accessible seats in different parts of the room; the 42” window counter doesn’t count unless part of it is lowered.

The occupant load is where small cafés get surprised. Seating: 600 ÷ 15 = 40. If the reviewer also counts about 150 sq ft of queue as standing space (÷ 5 = 30), the total passes 49 and a second exit comes into play.

+--------------------------------------------------+

A 3,000 sq ft casual restaurant

Dining seats: 13 two-tops along a banquette (26, combinable), 10 four-tops (40), 2 four-person booths (8) and 1 six-top round (6) make 80. Accessible seating: 4 in the dining room and at least 1 at the bar.

Occupant load: 1,150 ÷ 15 = 77, three fewer than the 80 chairs. That is exactly the gap to settle with the plan reviewer: drop a two-top, count the booths as fixed seats, or show added exit capacity. With the bar, waiting area and kitchen the load passes 100, so expect two separated exits, out-swinging doors, panic hardware on latching doors and 44-inch aisles.

How to draw your own restaurant floor plan

Step by step

1. Measure. Ask the landlord for existing drawings, then check them with a laser measure. Note columns, ceiling height, doors and windows.
2. Pick a scale. On quarter-inch graph paper, one square equals one foot.
3. Mark what you can’t move: exits, plumbing, drains, gas, the hood, the electrical panel.
4. Block the zones at 60/40, then adjust for your concept.
5. Lay out the kitchen along its utilities and draw the pass.
6. Draw the legal lines before the furniture: exits, the 36-inch accessible route, main aisles.
7. Place tables with scaled cut-outs that include each chair’s 19-inch occupied zone.
8. Trace the flows: guest in, to a seat, to the restroom, out; server from kitchen to table to station; food out; dirty dishes back. Where lines cross, move something.
9. Count seats, accessible seats, occupant load and restroom fixtures.
10. Test at full size. Tape the layout on the empty floor, set out chairs and walk it with a loaded tray. Then take it to your architect, building department and health department.

Free tools that exist

• Graph paper and cut-outs. Still the fastest way to try ten arrangements.
• draw.io: free, open source, no sign-up, with a Floorplans shape library, snap-to grid, and layers so walls stay locked while you move tables.
• Sweet Home 3D: free, open-source interior design software for Windows, macOS and Linux, plus a browser version, with a 2D plan and 3D view.
• Floorplanner: a free plan with up to 5 projects; free exports are standard-definition with a watermark (as of September 2026).

None of these checks code compliance. Your building department can tell you whether permit drawings must come from a licensed professional.

Common mistakes

• Dividing the lease’s total square footage by sq ft per seat instead of the real dining floor.
• Measuring aisles from table edges and forgetting the chairs.
• A room of four-tops for a crowd that arrives in twos.
• A host stand or café queue in the door swing or exit path.
• Service stations in the main aisle, or a restroom route through the kitchen.
• Fixing the seat count before running the occupant load.

Where Platevio fits (and where it doesn’t)

Once the room is open, the drawing’s job is done. Platevio is a free, browser-based restaurant POS with a floor plan editor: you drag tables into the layout of your real room. During service each table shows its state at a glance: seated, waiting on the kitchen, ready to pay or settled. A host or manager sees which tables are about to free up without walking the floor. It runs on the phones, tablets and laptops you already own, and a change on one device appears on the others without reloading.

Be clear about what it is not. Platevio’s floor plan is a live map for running service, not an architectural or CAD tool. It does not calculate seating capacity, occupant load, aisle widths, restroom counts, or ADA or code compliance. It has no reservations or waitlist, so the host stand’s booking book stays separate. Draw the building with the tools above; use Platevio to run the room once it’s open.

It is written for cafés and bars as much as for restaurants, and sent orders can go to a kitchen display at the pass. Free. No card, no plan. Once your tables are in place, it is worth trying on your own floor.
