50-inch TV: dimensions, viewing distance and VESA
A 50-inch 16:9 screen measures 43.6 x 24.5 in (111 x 62 cm) — 83% of the picture area of a 55-inch. Sit about 6 ft 9 in away for everyday viewing (SMPTE 30°) or 5 ft for a cinema-style view (THX 40°). Of the 7 50-inch models listed here, the most common VESA pattern is 200 x 200 mm (5 models).
Screen dimensions
TV size is the screen's diagonal. For a 16:9 panel the width is 0.8716 times the diagonal and the height 0.4903 times, so a 50-inch screen is 43.6 in wide and 24.5 in tall. The TV itself is larger by its bezel and, on most models, deeper than the panel at the back where the electronics sit; check the maker's "dimensions without stand" before measuring a recess. The step down to 48-inch takes 1.7 in off the width; the step up to 55-inch adds 4.4 in.
Where a 50-inch TV fits
A 50-inch set suits a small living room or a large bedroom, and is the size where most TV lines start to offer their better panels. Its SMPTE distance of 6 ft 9 in is shorter than many living rooms, so check your actual seating distance before deciding it's big enough.

How far to sit from a 50-inch TV
| Basis | Distance | In feet | What it means |
|---|---|---|---|
| SMPTE 30° (mixed viewing) | 81 in | 6.8 ft | Screen fills a 30° view — the widely quoted everyday figure. |
| THX 40° (cinema) | 60 in | 5 ft | A wider 40° view, THX's figure for film. |
| 4K (3840 x 2160) detail limit | 39 in | 3.3 ft | Farthest seat where 20/20 eyes still resolve single 4K pixels. |
| 1080p (1920 x 1080) detail limit | 78 in | 6.5 ft | Farthest seat where 20/20 eyes still resolve single 1080P pixels. |
| 8K (7680 x 4320) detail limit | 20 in | 1.6 ft | Farthest seat where 20/20 eyes still resolve single 8K pixels. |
Read the last rows the right way round. Closer than the 1080p limit (6 ft 6 in), a 1080p picture shows visible pixel structure and 4K looks sharper; farther away, 1080p already reaches the limit of 20/20 vision. Notice where the two standard seats fall: the SMPTE seat (6 ft 9 in) is just beyond the 1080p limit, so at the everyday distance 4K is barely distinguishable from 1080p, while the THX seat (5 ft) is well inside it, so for a cinema-style view 4K clearly helps. That relationship holds at every size because all three distances scale with the diagonal. 4K's own pixels are only resolvable within 3 ft 3 in, and 8K's within 1 ft 8 in — which is why 8K adds nothing you can see from a sofa.
VESA patterns on 50-inch TVs
3 different patterns appear at this size: 200 x 200 on 5 (71%), 200 x 300 on 1 (14%), 300 x 300 on 1 (14%). Size alone does not tell you the pattern — look up the model. Weights without stand run from 18.6 lb (Samsung UN50U8000HFXZA) to 34.6 lb (Sony K50XR70M2), median 21.6 lb — a spread wide enough that a mount rated for one 50-inch TV may not hold another.

| LG 50UT7550AUA | UT7550 UHD | 200 x 300 mm | 19.2 lb |
| Samsung UN50M70HAFXZA | Mini LED M70H | 200 x 200 mm | 18.7 lb |
