1. What is Throw Distance?

Throw distance is the distance between the projector lens and the screen. For Barco projectors, this distance is calculated based on the screen width and the projector's throw ratio.

2. How Does the Calculator Work?

The calculator uses the throw distance formula:

\[ \text{throw\_distance} = \text{screen\_width} \times \text{throw\_ratio} \]

Where:

\( \text{throw\_distance} \) — Distance from projector to screen (feet)
\( \text{screen\_width} \) — Width of the projection screen (feet)
\( \text{throw\_ratio} \) — Projector's throw ratio (dimensionless)

Explanation: The throw ratio is a specification provided by projector manufacturers that determines how far the projector needs to be from the screen for a given image size.

3. Importance of Throw Distance Calculation

Details: Proper throw distance calculation ensures optimal image quality, proper focus, and correct installation of the projector in the intended space.

4. Using the Calculator

Tips: Enter screen width in feet and the projector's throw ratio (available in the projector's specifications). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find my projector's throw ratio?
A: The throw ratio is typically listed in the projector's specifications or user manual. For Barco projectors, check the product documentation.

Q2: What if my projector has zoom capability?
A: Projectors with zoom lenses will have a range of throw ratios (e.g., 1.5-2.0:1). You can calculate minimum and maximum throw distances using this range.

Q3: How does screen aspect ratio affect this calculation?
A: The calculation uses screen width, so aspect ratio doesn't directly affect it. However, different aspect ratios may require different screen sizes for optimal viewing.

Q4: Should I add extra distance for installation?
A: Yes, it's recommended to add some extra space for cable management, ventilation, and potential future adjustments.

Q5: What about ultra-short throw projectors?
A: Ultra-short throw projectors have very small throw ratios (often less than 0.4) and can be placed much closer to the screen than standard projectors.
