Restaurant booth dimensions,
the planning guide
A standard restaurant booth has an 18-inch seat height for a 30-inch table, a seat 18 to 20 inches deep, a back 36 to 48 inches tall (42 inches is common) and about 24 inches of seat length per guest. Back-to-back booths are usually spaced about 72 inches center to center with a 30-inch table, and main aisles should stay at least 36 inches wide, 42 to 48 inches where traffic is heavy. These are industry reference values for planning; custom booths can change any of them to fit your room.

ADA notes for dining rooms
The 2010 ADA Standards require at least 5 percent of dining surfaces to be accessible. Accessible tabletops are 28 to 34 inches high with knee clearance at least 27 inches high, and they need a clear floor space and an accessible route of at least 36 inches. A booth seat is usually not the accessible option, so dining rooms combine booths with accessible tables. Your architect confirms the final layout.

What is the standard height of a restaurant booth seat?
The common reference is 18 inches from the floor to the top of the seat for a standard 30-inch dining table, which leaves about 12 inches between seat and tabletop. Bar-height booths raise the seat to match a 42-inch table.
How deep is a restaurant booth seat?
Most booth seats are 18 to 20 inches deep. Deeper seats of 20 to 22 inches feel more lounge-like but need a table that reaches closer to the guest.
How tall is a restaurant booth back?
Booth backs typically range from 36 inches (quick service and traditional) to 42 inches (a common standard) and 48 inches (casual and upscale). Privacy booths can reach 60 inches or more.
How much booth length does each guest need?
Plan about 24 inches per guest for standard table service, 20 to 22 inches for tight casual seating and around 30 inches for fine dining. A 48-inch booth seat therefore seats two guests comfortably.
How much space do back-to-back booths need?
A common reference is about 72 inches center to center between booth backs when using a 30-inch-deep table: two seat depths plus the table between them.
Do restaurant booths have to be ADA compliant?
The ADA requires at least 5 percent of seating and standing dining surfaces to be accessible, with tabletops 28 to 34 inches high and knee clearance of at least 27 inches. Booths themselves are usually not the accessible option, so plan accessible tables elsewhere in the room and confirm with your architect.
