Edit in the full tool

A 98-inch TV is 7.1 feet (2.2 meters) wide, so measure the wall first. Then check the room depth, because the seat range for a screen this size is long.

How this is calculated

The THX 40-degree seat for a 98-inch is 9.8 feet (3.0 meters), and the historical SMPTE EG 18-1994 30-degree seat is 13.3 feet (4.0 meters). SMPTE withdrew EG 18 in 2003, so use the 30 degree number as a geometry reference, not a current recommendation. A 4K panel of this size has 45 PPI, and closer than 6.4 feet (1.9 m), a 20/20 eye can pick out single pixels.

Verdict

Sit between 9.8 feet (3.0 m) and 13.3 feet (4.0 m) from a 98-inch TV. Closer than 9.8 feet (3.0 m), the screen runs past a 40 degree view, and you'll have to turn your head to follow the edges. Farther back than 13.3 feet (4.0 m), it covers less than a 30 degree view and starts to look small on the wall. If your room is shallower than 9.8 feet (3.0 m), a smaller TV suits it better.
