FAQ
How big is a 55 inch TV?
A 55-inch TV screen measures 47.9 inches wide by 27.0 inches tall (121.8 × 68.5 cm), with a 139.7 cm diagonal. Add roughly 0.5–1 inch for bezels depending on the model.
How far should I sit from a 55 inch TV?
For 4K, about 1.5× the screen height: 3.4 ft (1.0 m). For 1080p, about 3× the height: 6.7 ft (2.1 m). 4K panels stay sharp at much closer distances.
Will a 55 inch TV fit on my media console?
The screen is 47.9 inches (121.8 cm) wide, so choose a console at least that wide for stability — wider if the TV uses feet near the edges rather than a center stand.
