Size for distance / 16 feet
What size TV for 16 feet away?
From 16 feet (192 in, 488 cm), a 118-inch screen fills the SMPTE 30° everyday view and a 160-inch screen fills THX's 40° cinema view. The nearest common sizes are 115" and 115".
The numbers for 16 feet
| Basis | Screen size | Screen width | Reading it |
|---|---|---|---|
| SMPTE 30° (mixed viewing) | 118" | 102.9 in | The screen fills 30° of your view — the comfortable everyday figure. |
| THX 40° (cinema) | 160" | 139.8 in | The screen fills 40° — immersive for film, a lot for news and sport all day. |
| 4K's own pixels visible from | 246" | 214.5 in | Only screens this big show 4K's pixels to 20/20 eyes from 16 ft — the point where 8K would start to help. |
| 4K looks sharper than 1080p from | 123" | 107.2 in | On smaller screens, 1080p already reaches the limit of 20/20 vision from 16 ft, so 4K adds no visible sharpness. |
At 16 feet the point where 4K looks sharper than 1080p, 123 inches, falls between the SMPTE and THX sizes: at the everyday size the difference is marginal, at the cinema size it is visible. 4K's own pixels only become visible from 16 feet on a 246-inch screen — larger than any TV listed — which is why 8K adds nothing you can see at this distance.
What a 16-foot room usually looks like
Sixteen feet is beyond the depth of most living rooms and into home-cinema planning. Even the everyday 30° view needs a screen larger than any TV listed here, so this is projector territory.
16 feet is beyond what any TV listed here can fill to the 40° cinema view — that would take a 160-inch screen, while the largest listed is 115 inches. Even the 30° everyday view needs 118 inches. Rooms this deep are projector rooms, or rooms where the seating should move closer to a large TV.
Compared with 15 feet, every extra foot of distance adds about 7 inches to the SMPTE size and 10 to the THX size. No TV listed here reaches even the SMPTE size at this distance.
Choosing within the range
The two standards bracket a sensible choice rather than giving one answer. Lean toward 118 inches for a room used for news, sport, gaming at a desk distance, or a bright room where a huge black rectangle dominates when the set is off. Lean toward 160 inches for a room built around films. Your eyes, not the chart, settle it: if you turn your head to follow the action, the screen is past 40° for you; if you lean forward to read captions, it is under 30°.
Measure from where your eyes are when seated to where the screen will be — not from the wall. A TV on a stand sits several inches in front of the wall, and a full-motion mount can bring it forward a foot or more. For comparison, the SMPTE distance for a 55-inch is 7 ft 5 in and the THX distance for a 65-inch is 6 ft 6 in.
TVs to look at for 16 feet
No size listed here falls between 118 and 160 inches exactly; the closest are the 115-inch and 115-inch pages.
Sizes are geometry from the viewing angles and the 20/20 acuity limit cited by Wikipedia's Optimum HDTV viewing distance article, for a 16:9 screen. Viewing distances are geometry from published viewing angles: a 16:9 screen's width is 0.8716 x its diagonal, and the distance at which it fills a horizontal angle A is width / (2 x tan(A/2)). Resolution distances use the 20/20 acuity limit of one arcminute per pixel. The same formulas reproduce the reference figures quoted in the source (30 degrees = 1.6264 x diagonal; 31.2 degrees for 1080p; 58.37 degrees for 4K).
