What size TV for 3 metres (about 10 feet)?

Is 3 metres your real distance?

Measure from your eyes, not the sofa’s front edge. When people say “3 metres” or “10 feet” they often mean wall-to-wall; seated eye-to-screen is usually 0.5–1 m (roughly 2–3 ft) less, so check the table again at your real number.

Why do the makers’ guides give a different number?

Samsung’s and LG’s Korean buying guides answer with a single rule: recommended distance = screen diagonal (cm) × 1.2, which both state is a 40° view. Reverse it and 10 ft gives about 100″ — the same as the top of our range. We add 30° (the commonly cited minimum viewing angle) as the bottom, so the makers’ figure always matches our upper number, and anything above 30° is a size that will not feel small.

TV size by distance: the makers’ ×1.2 rule against the 30° and 40° references

Distance	Makers’ rule (×1.2 = 40°)	Our 30° (lower)	Our 40° (upper)
7 ft (2.1 m)	about 70″	52″	70″
8 ft (2.4 m)	about 80″	59″	80″
10 ft (3.0 m)	about 100″	74″	100″
12 ft (3.7 m)	about 120″	89″	120″

Why not just buy the biggest?

Past roughly 50° the screen spreads beyond comfortable central vision, which suits films more than news or sport. A 98″ set at 3 m (10 ft) is about 40°, a home-cinema feeling. Wall width, delivery access and price per inch usually set the limit first.

The two sizes people weigh up at 10 feet

Around 10 ft the choice is usually 75″ or 85″: see the width, height and area difference and the angle at each distance in 75 vs 85 inch TV. A little closer, around 8 ft, read 65 vs 75 inch TV. Any other distance: the TV size calculator.
