If you are matching a TV to furniture you already own, our TV stand size guide lists standard stand widths, and the screen size guide compares diagonals across device types.
| Size | Screen (W × H) | Area | vs 50 in |
|---|---|---|---|
| 43 in | 37.5 × 21.1 in | 790.1 sq in | -26% screen area |
| 50 in (this size) | 43.6 × 24.5 in | 1068.2 sq in | — |
| 55 in | 47.9 × 27 in | 1292.6 sq in | +21% screen area |
Because screen area scales with the square of the diagonal, a small step up in inches is a larger jump in picture size than the numbers suggest.
The screen of a 50-inch TV is 43.6 inches (110.7 cm) wide. Including the bezel, the overall cabinet is typically 44.6 inches wide, though this varies by model.
Between 4 ft 12 in and 6 ft 9 in. The THX 40° standard puts you at 4 ft 12 in for an immersive picture; the SMPTE 30° standard suggests 6 ft 9 in for mixed viewing.
At least 43.6 inches wide to match the screen, and ideally 49.6 inches or more so the TV does not overhang the furniture.
The screen is 24.5 inches (62.3 cm) tall. With a stand attached, add roughly 2–4 inches of pedestal height depending on the design.
It suits a seating distance of roughly 4 ft 12 in or more. Closer than that and you may notice pixel structure on lower-resolution content; a 4K panel tolerates closer seating than 1080p.
