Enter your screen width, aspect ratio, and throw ratio into the calculator to determine the necessary throw distance for your NEC projector.

Throw Distance Calculation Formula

The following formula is used to calculate the throw distance for your NEC projector.

Throw Distance = Screen Width * Throw Ratio / 12

Variables:

  • Throw Distance is the distance between the projector and the screen (feet)
  • Screen Width is the width of your screen (inches)
  • Throw Ratio is the ratio of the throw distance to the screen width

To calculate the throw distance, multiply the screen width by the throw ratio and divide the result by 12 to convert inches to feet.

What is Throw Distance Calculation?

Throw distance calculation refers to the process of determining the distance needed between a projector and the screen for the image to be properly displayed. This involves understanding the screen width, aspect ratio, and throw ratio specific to the projector model. Accurate throw distance calculation ensures optimal image quality and placement.

How to Calculate Throw Distance?

The following steps outline how to calculate the throw distance using the given formula.

  1. First, determine your screen width in inches.
  2. Next, identify the throw ratio of your projector.
  3. Use the formula from above: Throw Distance = Screen Width * Throw Ratio / 12.
  4. Calculate the throw distance by plugging in the values.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Screen Width = 120 inches

Throw Ratio = 1.5

Aspect Ratio = 16:9

FAQ

1. What is throw ratio?

Throw ratio is the ratio of the distance from the projector to the screen to the width of the projected image.

2. How is throw distance different from throw ratio?

Throw distance is the physical distance between the projector and the screen, while throw ratio is a dimensionless number that relates the throw distance to the screen width.

3. How often should I use the throw calculator?

It’s helpful to use the throw calculator whenever you set up a projector in a new location or change the screen size.

4. Can this calculator be used for different projector models?

Yes, you can use the calculator for different projector models by adjusting the throw ratio to match the specifications of each model.

5. Is the calculator accurate?

The calculator provides an estimate of the throw distance based on the inputs provided. For exact figures, it’s best to consult the projector’s manual or technical specifications.
