TVHow Far to Sit From a 43” TV — Viewing Distance
4.3–5.7 ft
Recommended viewing distance for a 43” TV — that's 1.31–1.75 m or 131–175 cm.
A 43-inch TV has a 16:9 picture roughly 37.5” wide and 21.1” tall (95 × 54 cm). For a cinematic, immersive image the THX 40° guideline puts your seat about 4.3 ft away; for relaxed, everyday viewing the SMPTE 30° guideline suggests about 5.7 ft. With 4K content you can move as close as 3.6 ft before pixels become visible. This is a mid-size screen, and 4K is worth it and lets you sit closer; 1080p is acceptable if your budget is tight.

Frequently asked questions
How far should I sit from a 43 inch TV?
Sit about 4.3 ft (1.31 m) away for an immersive, THX-style 40° view, or up to 5.7 ft for a relaxed SMPTE 30° view. With 4K you can sit as close as 3.6 ft with no visible pixels.
What are the dimensions of a 43 inch TV?
The 16:9 picture area is about 37.5” wide × 21.1” high (95 × 54 cm). The physical product is a little larger once you add the bezel and stand, so leave a few extra cm when planning a cabinet or recess.
Is a 43 inch TV too big?
It's a comfortable, mainstream size. If your sofa is more than 5.7 ft away you could happily go larger and still be within the recommended range.
What size room do I need for a 43 inch TV?
Plan for a seating distance of roughly 4.3–5.7 ft. The screen is about 37.5” (95 cm) wide, so allow a little wall margin on each side and keep the center near seated eye level.
