What TV size at 6 feet in a living room?

About 44 inches, typically 40–49. SMPTE 30° mixed viewing. Recheck wall width and the mount before you buy.

Why is a bedroom TV smaller than a living-room TV at the same distance?

Bedroom viewing is closer to the pillow line, so we scale the SMPTE size down about 10% versus the same tape-measure distance on a sofa.

Use 40° as the headline in a basement theater. Living rooms stay on SMPTE 30° unless you want cinema fill.

The short version

Pro Tip

"If you're between sizes, always go larger. Eye strain mostly comes from low resolution or brightness, not size."

For a theater-like feel, consider going up to 60" screen. Recommended for dark rooms and 4K content.

At this distance, 4K is perfectly sharp. You won't see individual pixels, just lifelike detail.
