The drawing below offers some basic guidelines for restaurant and cafeteria table capacities.
Seating capacities are based on standard chair sizes.
If large, swiveling or castered chairs are used, adjust accordingly.
Having the right combination of sizes of tables in a restaurant can decrease wait time for customers and can maximize seating capacity and profit.
Use small tables in small restaurants and then combine them to accommodate larger parties. Be aware that combining tables may cause some temporary seating capacity loss (e.g. two 4-person tables combined to seat only six customers).
Try to avoid using large dedicated tables (eight-person or larger) in small restaurants. This will help to save space and seating capacity.
Using some large seating capacity tables in larger restaurants creates “special” areas. Using a few large tables also helps to break up the space and enhances overall ambiance and reduces customer discomfort caused by crowding many small tables into a large space. In larger restaurants there will often be sufficient numbers of large parties to offset the seating capacity loss caused by large size restaurant tables.
