Building your own home theater space can be one of the most exciting and rewarding home improvement projects you ever undertake. But how do you get started planning out your home theater dimensions and figuring out how to configure the room? Not only is it worth considering the spacing between seating rows, but you’ll also want to think about the distance from the screen and the walls. We’ve compiled some information to take into consideration when planning your space and deciding how many home theater seats you need, including answers to what is the best home theater seating distance from the screen and between rows. This will ensure that you get the most out of your new entertainment space.

The first thing to consider when looking at your home theater room size is how many people you want to accommodate. The larger the gatherings you’re planning, the more space you’ll need. However, many people look to convert an existing room into a theater, which means that it might need to work the other way around: The number of people you can host may depend on your home theater’s size. Choose a room that’s at least 15 feet wide and 20 feet long and you should have a good basis to start building your home theater. You may be a bit cramped if you opt to go smaller than this minimum home theater room size. Don’t forget to include space for things like your home theater equipment and optional pieces of furniture like a concession stand, bar, or tables.

Your screen size will have the biggest effect on the comfortable seating distance from the screen. According to the Society of Motion Pictures and Television Engineers, or SMPTE, your home theater layout should give each seat a view of the entire screen that’s within a 30-degree field of view, so you’ll need to do a bit of math to calculate the theater seating dimensions that will keep everyone comfortable. Viewers sitting too close may experience discomfort and eyestrain, while seats set too far away lose the benefits of HD and widescreen resolution.

The following suggestions are designed to give you a basic idea of dimensions for your design. If you want more precise measurements, we recommend that you reference Carlton Bale’s home theater calculator.

For the easiest way to determine minimum and maximum distances from the screen, follow this simple formula: Take the horizontal width of your screen (NOT the diagonal width) and multiply it by 2 to get the minimum distance. Multiply by 5 to get the maximum distance.

For example, if your screen is 70 inches across, your first row of seats needs to be at least 140 inches, or 11 feet 8 inches, away from the screen.

Your last row of seats needs to be no farther than 350 inches, or 29 feet 2 inches, away from the screen.

If you need more room, you can decrease the space between rows. Just make sure that you do not make it less than 14 inches: This is the minimum space required for comfortable access.

How Tall Should a Riser Be in a Home Theater?

It’s a common question we hear all the time: What seating layout is going to deliver the most comfort and the best experience for your family? Let’s explore the options:

This is one of the most attractive layouts in home theaters today, and rows of two seats can be ordered in a range of variations to suit your needs. A straight row of two seats means the seats sit next to each other, connected by a straight arm. A loveseat is another popular option; this is a straight row of two seats that do not have an armrest placed between them. Finally, you can choose a row of two chairs with a curved armrest in between, which is called a curved row of two. The curved format provides a slightly different viewing angle but also does take up the most space.

Rows of three seats are the most popular choice we see in home theaters today. Very often, our customers will purchase two rows of three seats for a total of six chairs.

Consider a row of three straight seats (image A), a row of three as a reclining sofa (image B) where there are no armrests between the middle seats, or a row of three chairs with a left loveseat (image C). We do also offer rows of three with a right loveseat in a straight configuration.

Curved rows of three seats are also shown below in similar variations except for the sofa option, which isn’t possible because there are no arms in between the seats to make the curve.

The straight row of four seats with a middle loveseat is a family favorite. The center chairs in this layout do not have an armrest between them. If you do want this type of arrangement but want to have an optional armrest, we have a solution for that, too: the Octane “shark” arm. This portable armrest slides in between the seats with a “fin” and can be removed and stored when not needed.

Standard layouts for this setup are two rows of four theater seats either in a straight or curved configuration. This is an excellent choice if you plan to entertain your friends and family in your home theater.

Rows of five theater seats can accommodate many variations, including loveseats placed on either end with a single position in the middle (image C), as well as straight individual reclining seats making a row of 5 (image A). Another popular option is a sofa as the middle three seats in a row of 5. Keep in mind that when you’re including a loveseat or sofa option in your furniture layout, you save significant amounts of space because you are removing armrests.

Rows of six seats give you a large number of layout options. You can easily have three loveseats in a row (image C) or two single seats flanked by loveseats on either side (image B).
