When And Why Theater Riser Is Needed?

Look when your family size is greater than the front row seats of home theater then you must consider a home theater riser.  Due to this riser, anyone from any row of seats can watch the movie and can enjoy it equally.  If your audience can accommodate in a single row then you don’t need a riser.

Just look into the illustration below to tell you why you need it.

Before Riser

You can see everyone in the second and third row is frustrated, they can’t watch the screen properly because the projector’s screen is covered by the heads of the first-row audience.

This will affect the movie experience for them very badly.  If I am one of those people, I will stop watching movies on home theater again if I repeatedly get a position in the second and third row. 

 Home theater is meant to be enjoyed by everyone in the family because after that you can call it a home theater. It is for everyone in the home to enjoy it.

After Riser

why theater riser is needed for a home theater

Home theater rises is built for the second and third-row that lifts the seats of those rows a little from the first row.

 It depends on the size of your family to add steps to the riser.

Now the frustrated folks in the second and third-row will be happy because no one is there to cover the screen for them, their seats are on the higher end.

You will also need the best receiver and projector for the best watching experience. Read my these guides for best receiverOpens in a new tab. and best short throw projectorOpens in a new tab.

1. Here I Have 4 Ways For You To Get The Riser First

As we have discussed that the platform consist of riser and seats.

  • DIY Method
  • Buy a Readymade
  • Hire A Carpenter
  • Buy higher seats

The second part will be to buy seats

Don't forget to know about my Fomula below for the best viewing angle for the second row.

1# DIY Method

Whenever there are more than one rows of home theater seating you will have to construct a riser platform to lift the seats in the second or third room. 

How High Should The Riser Be?

Well, it depends on the distance from the screen and the height of the First row. It depends on your seating but normally a lift of 8 to 17 inches will be good. 

But to precisely find that value to make yourself confident about it then follow our theater riser formula in the calculator section.

Riser Height Calculator Formula

There is a simple formula for riser height calculation and that will erase all the guesswork during and even before the construction. 

By following this formula the second and third-row audience will clearly see the whole screen of home theater. 

We will create a variable for each value, so we can easily digest this formula.

SB = Distance from the bottom of the screen to the floor of the home theater

HF = Measurement value from the bottom to the head of the front row audience

HB = Measurement value from the bottom to the eyes of the back row audience (measurement without riser)

DF = Distance from the screen to front-row audience eyes

DB = Distance from the screen to back row audience eyes

HF-SB= VV1

VV1/DF =R

R×DB= VV2

VV2+SB= E2

E2-HB= Theater riser height

VV1= Vertical value 1, V2= Vertical Value 2, E2= this will be the exact value of the level of background audience size with the theater riser.

To make the result of this formula successful you will assume the same height of audience in both of the rows.

 You will adjust the values for shorter and taller peoples if you want to involve them as an audience.

You should follow the theater riser height value precisely otherwise it will be difficult for the back audience to see the full screen.

Pro Tip: kids can be seated in the front row and parents can sit in the back row.  It will adjust the height problem automatically and also the parents will have their privacy during the movie.

Riser Plans Construction And Installation

Let’s understand it step-by-step through illustration.  I love illustration because they are easy to understand.

 First, we will have to attach four planks of wood through nails and make a rectangle to create the base. You should first measure your seats and keep the riser length accordingly.

Now the basic structure of the theater riser is complete.

You can add more steps if you need more height of the riser.  But I am ok without the step as long as I can step on it without any difficulty because it is easy to construct. 

Now install planks of the woods between this rectangle.  These planks will be joists and will support the subfloor.  Leave empty space between each set of planks.  This empty space will be used for insulation.

You can also fish speaker wires in this riser for cleaner room. Know more tips like these from my 15 creative ways to hide home theater speaker wiresOpens in a new tab.

Riser Insulation Treatment

When the whole riser is completed, but the insulation is not done right then your movie experience will not be as good as you expected. 

You will experience echo problems in the movie.  It will be really annoying when you feel the vibration under your seat whenever the sound base is higher.

This is the only drawback of the riser that is bad for the movie experience. But don’t worry we can insulate the riser completely. 

Now get an insulation material online to stuff it in those empty spaces in the riser.  Now, whenever a sound enters into the riser the insulation material will observe it and will eliminate the echo problems. It will also erase the sound vibration in the riser.

Now a layer of vinyl or gym mat on the top of insulation will help to observe vibration even more.  It is optional but can help to enhance the experience more.

This will also help in the soundproofing theater room and stopping the sound reverberation. Read my this guide to completely soundproof the theater roomOpens in a new tab. and kill sound reverberation in it by acoustic panels installationOpens in a new tab..

Subfloor Installation

Now place the Subfloor on top of the joist and on the outer frame of the base structure.

Attached to the joist and the outer frame through nails or screws

Many experts will suggest two layers of subfloor. The second should be layered opposite to the first one. But it is not necessary because a single subfloor layer will do the work.

Riser Carpeting For Awesome Decoration

No one likes seeing a rough wood structure inside the home theater, Only if that is made up of premium wood, or it is polished well.

As we have installed subfloor and usually subfloors are made up of plywood and that is not a premium wood. That’s why we will need to carpet it at the end to make everything look good. To make it even better it will be a nice idea to find a carpet for the riser in a matching color to the home theater floor carpet.

This carpet will give one nice touch to the home theater.

2# How To Buy A Readymade Riser & How Much Will It Cost?

You can also buy the riser online but some are costly and some are cheap.

You can find an affordable riser for at least $80.  These risers are carpeted already.  So it will be a good deal if you find them in matching color.

Many people are not comfortable building their own riser or not comfortable with the nails and hammers. For them buying a riser will be a nice idea.

There are risers that are built into the seating but these types of risers are expensive.  This is a set of home theater seats that are taller than the front row because the riser is fitted in them.

 With more price, they come with more facilities and give a nice touch to your home theater.  They come with mobile and glass holders and a lighting system is built in them.

3# Hire A Carpenter Locally Or On Craigslist For Building A Riser For You

You can find a contractor to build a home riser for you. 

 In this way, you will have to pay even lesser than buying a riser. 

 You can discuss the concept of your riser with the contractor, so they can tell you if it is possible or not and how much it will cost you.

 You can even find good ideas on Pinterest and show them to your contractor. 

4# Get Higher Seats Than The Front Row Seats

 This section is for you if you are not interested in the DIY process or in hiring a contractor to construct the riser for you.

To completely eliminate the need for a riser you can also buy higher seats than the front row.  Now you don’t have to buy a riser or constructed one. 

 You can follow the riser formula above for buying seats for the second row too.  Because now you will precisely know to buy which height of seats for the second row.

FAQs:

What Is Stadium Seating In A Movie Theater?

Stadium seating is just like a theatre riser, but it is for more than 3 rows.

The Theatre riser consists of single to two steps while stadium seats consist of 3 to many steps. 

 In the home theater, you really don’t need Stadium seating as a theater riser will do the help.
