Read this if you don’t know already.

let me break it down for you in a step-by-step manner.

  1. You need an assistant and measuring tape. The assistant can be your Spouse or Child.
  2. Now hold the measuring tape at one end with the wall, where you will mount your projector screen or TV
  3. Now your assistant will hold another end of the measuring tape and should walk away from the wall
  4. The assistant should stop moving when they reach the middle of the room. Because after Seating you will also need to set up surround sound speakers around you.
  5. Let’s suppose the distance from the wall to the middle of the room is 85 inches
  6. Now, place this 85 inches distance value in the distance field of the above calculator
  7. This was the method of how to find the available distance in your theater room

After working for a month I realized that this is the best job in the world for me and it could be turned into a passion. Fast forward to when my internship ended, I joined my father as a full-time home theater equipment tester. I test new equipment and approve it before it can be installed in the customer's house. I love to test equipment and sometimes love to install it by myself in the customer's theater room. I have the right experience and knowledge to learn from my articles.
