TV Viewing Distance Calculator
Find how far to sit from your TV, or the right TV size for your room: the comfortable range, the cinema (THX) distance and the point where 1080p, 4K or 8K pixels become visible.
Quick answer: Sit about 1.5–2.5 times the screen’s diagonal away. For a 55-inch TV that’s about 7–11.5 ft (2.1–3.5 m); for a 65-inch, 8–13.5 ft (2.5–4.1 m). For a cinema-like view, sit closer, about 1.2 times the diagonal: 5.5 ft (1.7 m) for a 55-inch 4K TV.

How to Use This Calculator
Choose what you know
Pick My TV size to find where to sit, or My seating distance to find what size TV to buy.
Enter your screen and seat
Enter the screen's diagonal in inches, or tap a common size, then your seating distance from your eyes to the screen and the TV's resolution.
Read the range
The comfortable range suits everyday viewing; the THX distance gives a cinema feel; the pixel distance is the closest you can sit before the picture looks grainy.
TV Viewing Distance Chart by Screen Size
Comfortable seating distances for 16:9 TVs, using the 1.5–2.5 × diagonal rule, with the cinema distance and the closest you can sit before pixels show at 20/20 vision.
| TV size | Comfortable distance | Cinema (THX) | 4K: pixels visible closer than | 1080p: pixels visible closer than |
|---|---|---|---|---|
| 32" | 4.0 ft – 6.7 ft (1.2 m – 2.0 m) | 3.2 ft (1.0 m) | 2.1 ft (0.6 m) | 4.2 ft (1.3 m) |
| 40" | 5.0 ft – 8.3 ft (1.5 m – 2.5 m) | 4.0 ft (1.2 m) | 2.6 ft (0.8 m) | 5.2 ft (1.6 m) |

What Size TV for Your Viewing Distance
The best size fills about 30° of your view (SMPTE), the usual recommendation for a mix of films, TV and sport. Anything in the comfortable range works; the cinema size is for dedicated movie rooms with 4K or 8K content.
| Seating distance | Best size | Comfortable sizes | Cinema size (THX) |
|---|---|---|---|
| 5 ft (1.5 m) | 40" | 24–40" | 50" |
| 6 ft (1.8 m) | 43" | 29–48" | 60" |
| 7 ft (2.1 m) | 50" | 34–56" | 70" |
| 8 ft (2.4 m) | 55" | 38–64" | 80" |
| 9 ft (2.7 m) | 65" | 43–72" | 90" |
| 10 ft (3.0 m) | 75" | 48–80" | 100" |
| 11 ft (3.4 m) | 85" | 53–88" | 110" |
| 12 ft (3.7 m) | 85" | 58–96" | 120" |
| 13 ft (4.0 m) | 98" | 62–104" | 130" |
| 14 ft (4.3 m) | 98" | 67–112" | 140" |
| 15 ft (4.6 m) | 98" | 72–120" | 150" |
Best size is the nearest common size to the 30° recommendation. Over about 98 inches, a projector is often better value.
How Far to Sit From Your TV
There's no single perfect distance, but there is a comfortable range: 1.5 to 2.5 times the screen's diagonal. Closer than that and you have to move your eyes to follow the action; further away and a big TV starts to feel small and you lose the detail you paid for.
Cinema, everyday and the 30° rule
Two industry guidelines describe how much of your view the screen should fill. SMPTE recommends at least 30°, which for a 16:9 TV means sitting about 1.6 times the diagonal away: a good all-round distance for films, TV and sport. THX recommends about 40° for a cinema-like experience, about 1.2 times the diagonal. The closer figure is immersive with good 4K content but can be tiring for news or games with small on-screen text.
How resolution changes the closest distance
With 20/20 vision you can pick out detail down to about one arcminute (1/60 of a degree). Closer than the point where a single pixel is that size, the picture starts to look grainy. For a 16:9 screen that's about 1.56 × the diagonal for 1080p, 0.78 × for 4K and 0.39 × for 8K. That's why 4K lets you sit much closer, or buy a much bigger TV for the same room, and why 8K adds little at normal sofa distances.
Worked example: a 65-inch 4K TV. The comfortable range is 1.5–2.5 × 65 in = 97.5–162.5 in, or about 8–13.5 ft (2.5–4.1 m). For a cinema feel, sit about 1.2 × 65 = 78 in (6.5 ft / 2.0 m) away. At 4K, pixels only become visible closer than 0.78 × 65 = 51 in (4.2 ft / 1.3 m), so that seat is fine.
Measure from your eyes
Measure from where your eyes are when you're sitting back, not from the front of the sofa: a deep sofa adds 1–2 ft (30–60 cm). If several seats face the screen, check the furthest and the closest.
Height matters as much as distance
A TV at the right distance but mounted too high still strains your neck. Put the center of the screen at seated eye height, about 42 in (107 cm) from the floor for a typical sofa, and tilt it down if it has to go higher, for example above a fireplace. The TV mount height calculator works out the exact height and the bracket holes.
Bigger is usually better
Most people who upgrade wish they'd gone bigger, not smaller. If you're between two sizes and your seat is within the comfortable range for both, the larger one usually wins, as long as it fits the wall and leaves room for the furniture around it.
Frequently Asked Questions
How far should you sit from a TV?
About 1.5 to 2.5 times the screen's diagonal. For a 55-inch TV that's roughly 7–11.5 ft (2.1–3.5 m), and for a 65-inch 8–13.5 ft (2.5–4.1 m). Sit toward the closer end for 4K films and further back for everyday TV.
What size TV should I get for my room?
Measure from where your eyes will be to the screen and divide by 1.6: that size fills about 30° of your view, the SMPTE guideline for mixed viewing. At 10 ft (3 m) that's about 75 inches; at 8 ft (2.4 m), about 60 inches, so a 55 or 65-inch. The calculator does this and picks the nearest common size.
How far should I sit from a 55-inch TV?
About 7–11.5 ft (2.1–3.5 m) for comfortable everyday viewing, or about 5.5 ft (1.7 m) for a cinema-like view with 4K content.
How far should I sit from a 65-inch TV?
About 8–13.5 ft (2.5–4.1 m) for comfortable everyday viewing, or about 6.5 ft (2.0 m) for a cinema-like view, roughly 1.2 times the diagonal (the THX guideline).
What size TV for 10 feet away?
About 75 inches fills 30° of your view from 10 ft (3 m), and anything from about 48 to 80 inches is comfortable at that distance. For a cinema feel, up to about 100 inches.
Can you sit too close to a 4K TV?
Sitting close won't damage your eyes, though it can tire them. With 20/20 vision you can't make out 4K pixels beyond about 0.78 times the diagonal (3.6 ft / 1.1 m for a 55-inch), versus about 1.56 times for 1080p (7.1 ft / 2.2 m), so 4K lets you sit much closer. Closer than about 1.2 times the diagonal, you have to move your eyes or head to take in the whole screen.
What is the THX viewing distance?
THX recommends the screen fill about 40° of your view for a cinema-like experience, which for a 16:9 TV means sitting about 1.2 times the diagonal away. The SMPTE guideline of 30° works out to about 1.6 times the diagonal.
