All defaults are editable planning assumptions. Use actual product specifications and site conditions where possible.
How the estimate works
For a 16:9 screen, width = diagonal × 0.8716. Minimum and maximum lens-to-screen throw distances are width × the manufacturer’s throw ratios.
Where product limits or site conditions matter, confirm them against the exact model and installation before buying.
Understanding your result
The distance range indicates where the lens may sit for the chosen image width. It does not include the projector body depth, ceiling mount clearance or any restrictions on zoom and lens shift.
Choosing the right equipment
Confirm the exact model’s throw chart and screen aspect ratio. Measure from the lens to the screen, then check mounting height, ventilation, brightness and any required lens shift before ordering.
