Distance Impact: How 15 cm Changes Everything

Same panels, different seat-to-screen.

Practical Takeaways

• FOV drop: Backing off to 70 cm cuts 36.6° H-FOV and 8.0° V-FOV. Side angle relaxes from 67.6° → 55.5°.

• Trade-off: Relaxed side angles vs immersion. Decide if comfort is worth losing peripheral cues.

• Find your spot: Get as close as ergonomics allow: 55–65 cm is a common range, then compute FOV from that distance.
