Video Projection Tool

The vpt video projection tool provides a geometry-focused calculator for projector setups. It helps determine the correct throw distance, image dimensions, and zoom needs based on screen size and aspect ratio. The tool consolidates room measurements, screen geometry, and lens parameters into a single calculation model, enabling planners to validate installations before hardware is moved or mounted. Conceptually, the system treats projection as a simple yet precise geometric problem: given either a throw distance or a throw ratio, and the known screen width/height and aspect ratio, it yields the required image size and the proper zoom. Core features include grouped inputs for room and screen specs, unit handling (metric or imperial), and robust validation to prevent impossible configurations. Advanced options accommodate lens offset and keystone considerations, while supporting multiple size scenarios for quick comparison. The tool outputs essential values such as image_width, image_height, throw_distance_required, and zoom_factor, with clear guidance on how to adjust inputs if the image does not fit the screen. Typical use cases include classroom installations, conference rooms, event venues, and portable setups where reliable projection geometry reduces trial-and-error in planning and speeds up site surveys. By centralizing projection math in a single model, the tool helps AV teams, technicians, and educators finalize mounting positions, select appropriate lenses or projectors, and communicate setup requirements to stakeholders more efficiently.
