TV Size vs Wall Size Proportion
https://www.theatersizing.com/calculators/tv-vs-wall-size/
Estimate only — not a calibrated SPL meter, an acoustic report or an electrical design. Confirm with measurement.
TV Size vs Wall Size Proportion
A 85-inch panel on a 2 m alcove looks stuffed; a 43-inch on a 4 m wall looks lost. This is taste with a number, not a building rule.
Inputs

- TV width
- 1.44m
- TV / wall

- In 45–85% band?
- Yes
Calculation method
TV width from diagonal and aspect. Ratio = TV width / wall width. Balanced flag if 0.45–0.85.
Exact formula
r = W_tv / W_wall. Limits: no furniture, no fireplace, no gallery wall, 16:9 assumed unless you change aspect.
Frequently asked questions
Why 45–85%?
A practical living-room band. Galleries and IMAX rooms ignore it on purpose.
Include the soundbar?
This is panel width only. A wider bar can make a small TV look even smaller.
Gallery wall?
Tape it. The calculator cannot see art.
