Three 65‑inch TVs provide roughly 27 % more total viewable screen area than a single 100‑inch TV.
- One 100″ TV area ≈ 4,270 sq in
- Three 65″ TVs combined area ≈ 5,360 sq in
- Area advantage of 65″ trio ≈ 1,090 sq in (≈ 27 %)
- Three 65‑inch TVs provide more total viewable area than a single 100‑inch TV.
- Area calculations use the 16:9 formula (width = D·16/√(16²+9²), height = D·9/√(16²+9²)).
- Minor rounding differences: some models list the 100‑inch area as 4,267 sq in, others as 4,275 sq in.
Quick answer
| Configuration | Diagonal | Width (in) | Height (in) | Area (sq in) |
|---|---|---|---|---|
| 100‑inch TV | 100 | 87.2 | 49.1 | ≈ 4,270 |
| One 65‑inch TV | 65 | 56.7 | 31.5 | ≈ 1,790 |
| Three 65‑inch TVs | – | – | – | ≈ 5,360 |
Result: The three 65‑inch screens together give about 5,360 sq in, which is ~27 % larger than the single 100‑inch screen’s ~4,270 sq in.
How the numbers are derived
Aspect‑ratio relationship – Modern TVs are almost universally 16:9.
For a diagonal D the width W and height H are:[ W = D \times \frac{16}{\sqrt{16^{2}+9^{2}}},\qquad H = D \times \frac{9}{\sqrt{16^{2}+9^{2}}} ]
This formula is used by the Rtings size‑to‑distance calculator and DisplayWars visual comparison 12.
Calculate width & height
100‑inch TV
[ W_{100}=100\times\frac{16}{18.357}=87.2\text{ in},; H_{100}=100\times\frac{9}{18.357}=49.1\text{ in} ]65‑inch TV
[ W_{65}=65\times\frac{16}{18.357}=56.7\text{ in},; H_{65}=65\times\frac{9}{18.357}=31.5\text{ in} ]Area = width × height
100‑inch: (87.2 \times 49.1 \approx 4,270;\text{sq in})
One 65‑inch: (56.7 \times 31.5 \approx 1,790;\text{sq in})Multiply the 65‑inch area by three for the total of the three screens.
Percentage difference
[ \frac{5,360 - 4,270}{4,270} \approx 0.27 ; \text{or}; 27% ]
Why the difference matters
- Screen real‑estate: More total area can be useful for multi‑window setups, gaming rigs, or a “video wall” effect.
- Viewing distance: A 100‑inch panel is designed for a farther viewing distance (≈ 13‑15 ft) while a 65‑inch screen is optimal at ≈ 9‑10 ft 14. If you place three 65‑inch TVs side‑by‑side, the optimal viewing distance shifts toward the 9‑10 ft range.
- Bezel & gap: Real installations must account for bezel width and the physical gap between the three panels, which reduces the effective continuous image area slightly.
- Cost & mounting: Three separate units are usually more expensive and require a more complex mounting solution than a single large TV.
Bottom line
If pure screen area is the only criterion, three 65‑inch TVs beat a single 100‑inch TV by about a quarter. However, consider viewing distance, bezel gaps, mounting complexity, and price before deciding which configuration best fits your space.
