What is the optimal mounting height for a TopFloor floor laser?

The optimal mounting height depends on the desired line length. Rule of thumb: line length ≈ 2× mounting height at a 90° lens angle, or 3× at 110°. Real-world values: 5 m height → approx. 10 m line (90°) or 15 m (110°). 8 m height → 16–24 m. For shorter lines (e.g. a stop line) 3–5 m height with a narrow angle is enough. Also consider ambient brightness: in halls with very bright daylight choose a higher power (500 mW or 750 mW); otherwise 300 mW is sufficient. The TopFloor mount allows fine-tuned alignment in all directions.
