About Projector Throw Distance Calculator
Projector Throw Distance Calculator is published by Mycelgrid LLC as a browser-based projector planning tool.
Calculation scope
The app converts screen diagonal and aspect ratio into image width and height, applies fixed or ranged throw ratios, calculates screen-size ranges from distance, solves required throw ratio, and checks interval overlap for room fit.
Technical basis
The core relationship is throw ratio = throw distance ÷ image width. Screen geometry uses the selected aspect ratio and full floating-point precision internally. Display rounding is separated from the calculation.
Browser-local processing
Measurements and results stay in the current browser page for the session. Calculator operation does not require an account, database, remote calculation service, telemetry, or user-work storage.
Product recommendation boundary
The calculator works without shopping links. Any future projector recommendations must be separately activated, use owner-approved affiliate URLs, and verify the exact projector or lens throw-ratio specification from current manufacturer documentation before claiming compatibility.
Installation limits
Results are generic planning geometry. The app does not certify mounting, electrical work, screen gain, brightness, seating position, lens shift, offset, wall clearance, or model-specific installation. Follow the manufacturer manual for the exact equipment.
