Can I use this before drilling?

Yes. Use it to mark a starting height with tape, then check lease rules, studs, mount instructions, and cable safety before drilling.

Should a TV always be eye level?

Eye-level center height is a comfort-first starting point, but furniture, children, pets, and room layout may change the final setup.

Mounting caution

TV Height Calculator

Estimate a comfortable screen-center height using seating distance, eye height, and viewing style. This is a comfort guide, not a substitute for mount instructions or lease rules.

Recommended center height: 42 in

Start near seated eye level, then adjust slightly for room constraints.
