Now, let's go back to home theater seating considerations. If you just plan on having a couch in your home theater room, get a curved sectional. Since the optimal viewing in a movie theater is the center seat, a curved sectional will simulate that effect for everyone viewing your television.
If you do plan on having actual movie theater seats, you need to allow for aisle and arm space, which can range from 20 inches to 2 feet apart. Your aisle should be approximately two to three feet wide on either side and behind each row so that people can easily access the seats. You don't need to have a huge aisle behind the back row.
you should have about three to four inches between seats to accommodate arm rests and beverage holders. If you plan on having recliner seats, you need to allow at least three inches on the last row so that people can still recline their seats and not hit their heads. If you just plan on having a single row of seats up against the wall, you still need to allow three inches or more if you're going to have recliner seats.
When laying out your home theater seating, think about the size of your room. The size of your room will determine how many theater seats that you can accommodate. About two feet per seat is the normal. So, look at your room before purchasing your home theater seats.
Whatever seating that you decide to use, it's important to sketch out a layout of your home theater room to see what you can realistically accommodate as far as seats go in the room. You don't want to be cramped. It will make for a rather uncomfortable home theater viewing experience.
