You might have got a perfect home theater room accompanying all the audio and video tools that are required for enhanced entertainment through your favorite movies or TV shows, but what about the size and dimensions of the room?
In this article, we will describe all the necessary details to plan and build a perfect home theater room from dimension to the seating distance.
Best Sizes & Dimensions of the Room
Though there is no ideal size of a home theater room it is a general conception that bigger can be better. Also, the projector screen and the type of projector will be significant determinants in analyzing the dimension of a home theater. A Medium screen with an Ultra short throw projector needs a small room, however, a bigger screen with a long throw projector needs a bigger room.
The standard size and dimension for immersive experience are 20/15ft or 240 inches in length and 180 inches in width paired with a high ceiling. Theaters for smaller homes are also present that require 10ft sq. or 120 inches throughout. Pairing your projector in these rooms will add a movie theater feel within your comfort zone.
Home Theater Seating Dimensions
First and the most important factor is to think about how many people will be accommodated in the theater at one time. If the whole family is about to sit inside the home theater, more space and seating will be required.
The following factors play role in considering seating arrangements:
- Width of Screen: The first thing that matters is the width of the screen for viewing at an optimum distance that will change by changing the size of the screen. After knowing the width decision will be easier.
- Platform Needed for Second Row: There is a need for a platform in the second row that should be at least 7-inches to a foot to see over the seats of the first row.
- Number of Seats: Finding out the number of seats that could fit in a row also helps in making seating dimensions. Most standard theaters prefer to have four seats.
- Is an aisle needed? A side aisle of 3ft wide may be ideal for your home theater but it depends on whether an aisle is needed or not.
Space Required Between Home Theater Rows
The spacing varies between home theater rows counting on how big your home theater is and how much space you already have.
Usually, 20-inches or 51cm of space is considered good between each row of seats. However, adjustments can be made if reclining is needed.
Screen Size of Home Theater
To measure the screen size, you will need a measuring tape and a calculator. Though the bigger and better is good to go but you need to find out the optimum measurements to make a sensible decision.
First, there will be a need to decide whether you need a 16: 9 or 2.40 viewing ratio. Most home theaters have a 16:9 aspect ratio.
The second fact is to measure the distance from the screen to the seating position. The seating position can be your favorite spot in the middle or the front row.
For the middle position, at a 16:9 aspect ratio, the preference will be a 30-degree field of view. While for 2.40 aspect ratio, the people prefer a 42-degree field of vision.
For front seating, 36 degrees is an ideal field of vision in case of a 16:9 ratio and it will be a 30-degree field of vision for a 2.40 aspect ratio.
To decide about the exact screen size, you need to multiply the distance in inches by 0.6149 and the product. By rounding up or down, you will get the perfect size for your home theater screen in a diagonal position.
Viewing Distance According to Screen Size
Right calculations will be required to find out the accurate viewing distance for the home theater room. Factors such as screen size, seating adjustments, size of home theater, and screen height should not be ignored during the calculations.
By following the Society of Motion Picture and Television Engineers’ Recommendation (SMPTE), you can calculate the viewing distance. It uses the formula of dividing viewing distance by 0.6. The value you get in the end is the viewing distance converted to inches at a 30-degree angle.
Following THX’s recommendation is another way to follow. It involves dividing the screen diagonal size by 0.84.
These two ways are considered the best and easiest ways; however, you can also use different online available calculators for this purpose.
Ideal Shapes for Home Theater Room
Although, several shapes of home theater room can be used but we have mentioned a shortlist with details to help you find out one best as per your needs.
Golden Cuboid
This shape is purely cuboid with a 1.618 ratio. It makes the room dimension easy to design and also enhances the sound system.
You can apply the dimension by calculating it for creating a perfect shape for a home theater room.
Golden Trapagon
It is considered the perfect shape for a home theater room due to its ability to eliminate the nature of parallel walls. It leads to minimum bouncing effects of sound waves to get you an immersive sound experience.
This shape is used by most audio professionals and cinemas. Its ratio is supposed to be 1.272:1 which is perfect to design a trapagon that can reduce too much echo and reverberation.
Normal Trapagon
The room shape is quite similar to the golden trapagon in the case of a normal trapagon but the ratio varies in it. Though it is cuboid but has less difference in its rear and front walls.
This shape doesn’t have the best ratio so you might need to differentiate between rare and front walls by ensuring the viewing area is narrower than screen walls.
Acoustic Arrangements for Home Theater Rooms
You can make acoustic adjustments for your room by installing absorbent acoustic panels. These panels will help you get rid of standing waves by absorbing sound waves.
Diffusers
You might have experienced a great sound experience from a movie theater but the picture seems too dark. This could be due to improper absorption of sound by the room.
Placing the diffusers around the perimeter of the room will help in bouncing up some light by increasing brightness to deliver great viewing quality.
Bass Traps
Brass traps are purposely installed to absorb sound waves and then direct them back to the room. They aid in absorbing all sound frequencies except bass frequencies.
These are also meaningful in reducing the reflection and absorbing even mid-range frequencies.
