FAQ
How far should I sit from a 48 inch TV?
For a cinematic, immersive picture sit about 4.8 ft (1.46 m) away — the THX 40° angle. For a more relaxed, mixed-use setup go to about 6.4 ft (SMPTE 30°). With 4K you can sit as close as 4 ft without seeing pixels.
What size room do I need for a 48" TV?
Plan for a seating distance of roughly 4.8–6.4 ft. The screen itself is about 41.8" (106 cm) wide, so leave a little wall margin on each side.
Is a 48 inch TV too big?
It is a comfortable size for most rooms. If your couch is more than 6.4 ft away, consider going larger so the screen still fills your view.
