A restaurant layout is usually discussed as a look and settled as an arithmetic problem. The same floor area, arranged two ways, can differ by twenty per cent in what it takes on a Saturday, and almost none of that difference is visible in a photograph. This page is about the operational half: how the arrangement of tables decides which bookings you can accept, how the route the food takes eats covers you never counted, and what to work out before anyone moves furniture.
The table mix decides which phone calls you can say yes to
A room of eight twos seats sixteen people and can accept almost no party larger than four without joining tables and disturbing everyone around them. The same seats arranged as four fours and two sixes seats the same sixteen and says yes to a completely different set of bookings. Neither is right in the abstract: the correct mix is the one that matches the parties that actually ring you, which you can read off last month's book in ten minutes and which most restaurants have never looked at.
Circulation is not wasted space, it is the service
The temptation in every restaurant layout is to add two more covers by narrowing the route between sections. It works on the drawing and it costs you on the floor, because every plate now takes longer to reach a table and every table therefore turns slower. A room that seats fifty and turns twice takes more money than a room that seats fifty four and turns one and a half times, and the second room is also worse to work in and worse to eat in.
What restaurant layouts do to your turn time
Turn time is treated as a property of the menu and it is at least half a property of the room. Distance from the pass, whether a section can be seen from the host stand, how long a table takes to clear and reset, and whether the party has to move for anyone to get past all show up in the minutes. The worksheet on this site takes the turn and the reset as separate inputs because they are separately fixable, and it prices a single extra minute of reset across the year, which is usually the most persuasive number on the page.
The resturant layout decisions that cost a sitting
Three recur. Putting the largest table where it cannot be joined, so the parties you most want to take are the ones you must refuse. Filling the window first because it looks good from outside, and then having nothing to offer the eight o'clock booking that would have taken it anyway. And keeping a section open at the far end on quiet nights, which spreads the same covers over more floor and more steps than the service needs. All three are free to fix and none of them is visible until somebody counts.
Questions people ask about restaurant layout
How do I work out what my restaurant layout seats?
Count the tables off the plan by size, add the bar and counter seats that actually take bookings, decide honestly what share of the seats you fill, and divide the service length by the turn plus the reset to get the sittings. The free worksheet on this site does that arithmetic and gives you the covers a service, the week, and what the year is worth.
Is a bigger room always better?
No, and this is where restaurant layouts mislead people. More seats spread over more floor with the same kitchen and the same staff will usually turn more slowly, and the extra covers arrive with extra rent. Two turns of a smaller room beats one and a half turns of a larger one on almost every measure, including how the service feels.
Does this tell me my legal capacity?
No. It tells you what your table plan seats operationally. The occupancy a building is designed for is a separate calculation using published floor space factors, and what your premises may lawfully hold is decided by your own fire risk assessment and the authority that enforces it.
