Restaurant Booth Dimensions: Depth, Seat Height, Back Height and Aisles (2026 Guide)

Short answer: A standard restaurant booth has an 18 in (46 cm) seat height, an overall depth of 22–26 in (56–66 cm) for a single and 44–50 in (112–127 cm) for a back-to-back double, and a back height of 36, 42 or 48 in (91, 107 or 122 cm). Pair it with a 30 in (76 cm) high table that overlaps the seat front by 2–4 in, allow 24 in (61 cm) of seat length per guest, and keep accessible routes at least 36 in (91 cm) clear.

Those numbers will get you most of the way. The rest of this guide explains where each one comes from, when to depart from it, and the mistakes that turn a good floor plan into a booth that nobody wants to sit in.

What are the standard dimensions of a restaurant booth?

The table below collects the figures we use as a starting point when we draw booths for a US dining room. Every Banquette House booth is made to order, so treat these as defaults, not limits.

How deep should a restaurant booth be?

A single booth should be 22–24 in (56–61 cm) deep overall for a standard upright back, and up to 26–28 in (66–71 cm) for a thick, tufted or slightly reclined back. The number that matters to the guest is the usable seat depth, measured from the seat front to the face of the back cushion: 18–20 in (46–51 cm) suits most adults at a dining table.

Restaurant booths are shallower than lounge seating on purpose. At a dining table you sit upright and lean slightly forward to eat. A lounge-depth seat of 22 in or more pushes the guest away from the table, so they either slouch or sit on the front edge, which wears the seat front faster.

Back-to-back doubles share a central spine. With a 4–8 in (10–20 cm) spine and two 20 in seats, a double comes out at 44–48 in (112–122 cm). A very slim spine saves floor area across a long island row; a thicker spine allows a taller, more private back. Our Carroll High-Back Double Booth uses an 8 in spine because it rises to 54 in.

What seat height should a booth have?

Use 18 in (46 cm) to the top of the seat cushion for a 30 in (76 cm) dining table. That leaves about 12 in between seat and tabletop, the gap that lets an adult sit with their forearms comfortably on the table.

For other table heights, keep the same 10–12 in relationship:

Measure seat height on the drawing as the cushion height under load, not uncompressed. A soft cushion can sink an inch or more when someone sits down, which is why we specify firm, high-resilience seat foam over a solid base for commercial booths.

How tall should a booth back be?

The three standard heights are 36, 42 and 48 in (91, 107 and 122 cm), and each does a different job:

• 36 in (91 cm): Low and open. Guests can see across the room, which suits casual and fast-casual dining and keeps a room feeling bright.
• 42 in (107 cm): The default. Seated guests cannot see over it, so tables feel private, yet servers can still see the room.
• 48 in (122 cm) and above: A room within a room. Good for date-night restaurants, steakhouses and rooms that sell long dinners. It also blocks noise between tables.

Above about 54 in (137 cm), a freestanding booth must be firmly anchored to the floor, and you should check sightlines for staff, sprinklers and lighting. Our Quiet-Back Acoustic Booth goes to 59 in because its job is to absorb sound.

How big should the table be, and how far should it overhang the seat?

In a booth bay for four, the standard is a 30 × 48 in (76 × 122 cm) table between two 48 in booths. For two guests, a 24 × 30 in (61 × 76 cm) table between two shorter booths works.

The tabletop should overlap the front edge of each seat by about 2–4 in (5–10 cm). With no overlap, guests have to lean forward to reach their plate; with more than 4 in, they struggle to slide in and out. This is why the overall bay length for a four-top booth works out to:

Bay length = seat depth + table width + seat depth − overlaps

With 22 in deep booths, a 30 in table and 2 in overlap on each side, the bay is 22 + 30 + 22 − 4 = 70 in (178 cm) from back to back. Use that number to space a row of booths along a wall.

Choose single pedestal or wall-mounted tables wherever possible. Four-leg tables trap knees and make it harder to slide to the middle of the seat.

How much seat length does each guest need?

Plan on 24 in (61 cm) per guest for comfort, 22 in (56 cm) as the tight minimum. A 48 in booth seats two; a 60 in booth seats two generously or three tightly; a 72 in banquette seats three. Curved booths need a little more along the back because guests sit on a radius; calculate them along the seat front instead.

What aisle widths do booths need?

Aisles are where booth layouts most often fail inspection or service. Three numbers matter:

1. Accessible route: at least 36 in (91 cm) clear width under the 2010 ADA Standards for an accessible route to the accessible seating positions. Measure it from the furthest projection, such as a chair back in use, not from the table edge.
2. Main service aisles: 42–48 in (107–122 cm) is a common working figure for servers carrying trays past seated guests.
3. Egress: exit access aisle widths are set by the building and fire codes adopted in your jurisdiction and depend on occupant load. Your architect or fire marshal confirms these; do not guess.

Booths help aisle planning because, unlike loose chairs, they do not move into the aisle when guests push back.

Checklist: dimensions to confirm before you order

1. Finished wall-to-wall lengths for every run, measured at seat height and at back height (walls are rarely plumb).
2. Positions of outlets, vents, radiators, windowsills and switches along the wall.
3. Seat height and table height, with the actual table you will use.
4. Back height for each zone of the room.
5. Table size and overhang for every booth bay.
6. Aisle widths, including the 36 in accessible route.
7. Accessible seating positions, at least 5 percent of seating, with clear floor space marked.
8. Door widths, stair turns and elevator sizes on the delivery route, which limit section length.
9. Floor level: note any slope, so the base can be packed or adjusted.

Common mistakes

• Using lounge depths for dining. A 24 in seat depth feels luxurious in a showroom and wrong at dinner. Keep usable depth at 18–20 in.
• Forgetting the table overhang. Booths spaced without the 2–4 in overlap leave guests reaching across a gap.
• Ignoring the back thickness. Tufted and channel backs can be 4–6 in thick. If you plan the bay on seat depth alone, the row will not fit.
• Measuring once. A wall that is 23 ft at the floor can be 22 ft 10 in at 40 in high. Measure at two heights and at both ends.
• Making sections too long to deliver. A 12 ft section will not turn into a 36 in door off a narrow corridor. Split the run on the drawing, not on site.
• Four-leg tables in booths. They create the knee-clash and slide-in problem booths are supposed to solve.

How we use these numbers

At Banquette House (a line by EASEN Commercial Furniture) we draw every booth from your measured room. If your wall is not a standard length, the booth is not a standard length either. Browse the Wall Banquettes and Single, Double & Back-to-Back Booths collections to see the profiles, then send us your plan.

FAQ

What is the standard booth seat height?

18 in (46 cm) to the top of the seat cushion, under load, for a standard 30 in (76 cm) dining table. Counter-height booths use 24–26 in and bar-height booths about 30 in.

How wide is a standard restaurant booth?

Booths are sold by length rather than width. Common lengths are 36 in for one guest, 48 in for two and 60 in for two to three, and 72 in for three. A wall banquette is simply built to the length of the wall.

How much space does a four-person booth take?

A four-guest booth bay with 22 in deep booths and a 30 in table is about 70 in (178 cm) back to back, by 48 in (122 cm) long, before aisle space.

Can a booth be the accessible seating in a restaurant?

Not by itself. An accessible position needs a 30 × 48 in clear floor space at a dining surface 28–34 in high with 27 in knee clearance. A booth with an open end and the right table can provide that position; see our Access-End Booth.

What thickness should a booth back be?

A plain upholstered back is typically 3–4 in thick; channel or tufted backs 4–6 in. A slim-back design such as our Wythe uses about 2.75 in to save depth in small rooms.
