About this calculator

This calculator centers your TV screen on your seated eye line — the height ergonomists and home theater installers recommend for comfortable viewing without neck strain. It starts from the screen's diagonal size and aspect ratio to work out the actual screen height, then positions the screen's vertical center at your eye level when seated, which is typically 42–48 inches (107–122 cm) off the floor on a standard sofa, adjusted for your own measurements.

Home theater installers and TV-mounting professionals use this same eye-level rule as their starting point before accounting for glare, wall studs, and viewing distance, and it's the calculation homeowners reach for before drilling into drywall — since a TV mounted too high is one of the most common and hardest-to-fix installation mistakes.
