Throw ratio is projector distance divided by image width. Start with the intended visible image width and multiply by 0.496:1; then verify Optoma’s distance calculator, lens offset, mount adjustment, enclosure depth, player position and launch-monitor requirements before drilling.
For simulator planning, calculate placement from image width and the 0.496:1 throw ratio.
