Projector Throw
Projector Throw Calc is an offline utility for projector throw ratio and screen size math.
What does the app calculate?
The app is intended to help with:
- screen width, height, and diagonal from throw ratio plus distance
- estimated throw distance from a target screen size
- quick comparison of placement options using common aspect ratios
Does the app use the camera or AR?
No. Version 1.0 is positioned as a manual calculator only.
Does it recommend projector models or brands?
No. Projector Throw Calc does not include a projector database or shopping recommendations. You enter the throw ratio yourself from the projector specs you trust.
Does it need internet access?
No. Core calculations are intended to work fully offline.
Will the result always match a real installation?
Not always. Real-world results can vary based on zoom position, lens shift, projector tolerances, screen border, mounting offsets, and room measurements. Always confirm against manufacturer documentation and on-site measurements before final installation.
Are my calculations synced anywhere?
No. Version 1.0 does not require cloud sync or an account.
