About these results

  • Manufacturer data: calculations use official manufacturer specifications. Actual performance may vary depending on installation conditions.
  • Safety margin: plan for a 5% margin on throw ratio, shift, and lumens to account for differences between theory and field conditions.
  • Zoom lenses: when you select a zoom lens from the database, the throw ratio used is the midpoint of the range. The actual result varies depending on the zoom setting.
