Formulas

\(\displaystyle d_h = \sqrt{(x_t-x_s)^2 + (y_t-y_s)^2}\)
\(\displaystyle d = \sqrt{d_h^2 + (h_s-h_t)^2}\)
\(\displaystyle D = 2d\tan(\theta/2)\)

Calculate source-to-target aiming angle, throw, azimuth, and approximate beam diameter for a spotlight.

Spotlight Aiming Geometry Calculator is a planning aid. Keep the target source, product data, measurement method, and project assumptions with the result. Confirm compliance, installation, certification, and safety decisions with the responsible professional.
