  Banquettes can be made to fit almost any tight space, and can be built to fit curved or straight spaces. They can also fit neatly against a wall or perpendicular to it, according to The Washington Post.
  
  

Seat Height

• "Seat height is critical. So is clearance under the table," says Walter Gagliano, a designer quoted in the Washington Post. He adds that an average seat height is about 19 inches, and that you should be able to sit upright.
  
  

Seat Depth

• From front to back, optimum depth for a banquette is between 18 and 20 inches. Cushion thickness requires additional space, depending on your design.
  
  

Seat Backs

• Seat backs are completely adaptable to your design requirements. You can offer your guests the simplicity and informality of throw pillows or choose plushly cushioned, high seat backs such as those found at chic restaurants.
  
  

Table Height

• Convert a living room area into a dining area by adding a fold-away table. Keep in mind that the average tabletop ranges from 29 to 31 inches high.
