TThrowCalc
Calculator

Projector throw distance calculator by model

Pick your exact projector from 79 models and get the throw distance for any screen size — using each model’s real throw ratio. No spec sheet needed.

Calculator

Choose your projector from our database of 79 models and enter a screen size — the calculator uses that model’s actual throw-ratio range to give the exact placement distance. If you already know your throw ratio, the generic calculator works too.

Why a per-model calculator is more accurate

A generic throw calculator needs you to find your projector’s throw ratio first — and many spec sheets bury it or quote a zoom range. This tool stores the real throw-ratio range for every model in our database, so you just pick the projector and screen size. For zoom-lens models it shows the full near-to-far placement window, not a single number, so you can see how much flexibility you have.
