A standard bench for a deck is 18” tall. Two 4x4 support legs with 2x6 framing and trim is common construction. Benches are built two or three boards wide on a 2X6 frame. Blocking between the front and back framing member should be installed every 16” the same as the decking. Bench support legs can be placed every four to six feet. Trim on the bench is installed the same as the horizontal deck trim.
Most benches are framed out of 2x4, 2x6, and 4x4 material and covered with decking to create a solid surface to sit on that compliments the rest of the deck. Some benches use the rails as a backrest or may include one of its own.
