11 feet away
An 86-inch TV is the sweet spot at 11 feet. Anything from 81 to 98 inches sits in the SMPTE-to-THX range for mixed use; go larger for a dedicated movie room.
Best size at 11 feet
86"
32° viewing angle. Sizes that fit: 77, 83, 85, 86, 97, 98, 100 inches.
Dedicated movie room (36–40°)
98–110"
common sizes: 97, 98, 100, 110, 115
Mixed movies and TV (30–36°)
81–98"
common sizes: 77, 83, 85, 86, 97, 98, 100
Casual viewing (24–30°)
64–81"
common sizes: 65, 70, 75, 77, 83, 85, 86
Note: A 90 inch panel is the target, and it will look enormous in the box
Sitting 11 ft away makes 90 inches the right answer, which is bigger than most people picture. Measure 78 in of clear wall before buying, and check that the panel fits through your doorways and up your stairs. Almost nobody who buys at this size wishes they had gone smaller.
Watch: 4K detail is invisible past 5.8 ft
With 20/20 vision you stop resolving individual 4K pixels on a 90 inch screen beyond 5.8 ft, and your seat is at 11 ft. The resolution is not doing anything for you at this distance, so spend the budget on contrast and brightness instead, or move closer.

| 100" | 37° | Cinematic (THX) |
How we got these numbers
At 11 feet (132 inches) from your eyes to the screen, TV size is a question of viewing angle. SMPTE's cinema guidance calls for the screen to fill at least 30° of your horizontal view; THX recommends 36°, and 40° is the widely used cap for the best seat. Casual TV viewing is comfortable at 24° to 30°.
Each angle converts to a screen width (2 × distance × tan(angle ÷ 2)) and then to a 16:9 diagonal. At 11 feet that gives roughly 64 inches at 24°, 81 inches at 30°, 98 inches at 36°, and 110 inches at 40°.
Sizes are rounded to what stores actually sell. If you are between two sizes and the wall allows it, the larger one is almost always the better long-term choice; the most common regret is buying too small.

Bright rooms, gaming on a budget
The best value Mini-LED of 2026: bright enough for daytime rooms, a matte anti-reflection coating, effective local dimming, and full HDMI 2.1 bandwidth on all four inputs for consoles and PCs.
Dark rooms, movies, gaming
LG's 2026 mid-range OLED is the default recommendation for a dedicated movie room: perfect blacks, a brighter evo panel with the Alpha 11 Gen3 processor, and four full-bandwidth HDMI 2.1 ports.
Big bright rooms, sports and HDR movies
For a giant-screen setup without projector compromises, the 2026 QM8L pairs extremely high HDR brightness and thousands of dimming zones with near-invisible blooming and an anti-reflective wide-angle panel.
Vivid color and bright HDR on a budget
TCL's 2026 step-down Mini-LED uses the same SQD quantum-dot layer as the QM8L, which is why reviewers rate its color among the best at any price. Tom's Guide named it the best Mini-LED TV of 2026 and measured about 2,270 nits on a 10 percent window with 9.4 ms of input lag.
