Your sofa should sit about 1.2 to 2 times the TV's screen size away, measured from your eyes to the screen. For a 55-inch TV, that is about 5.5 to 9.2 feet. Both ends of that range come from Samsung's 2026 TV guides. Sony says a 4K screen can be watched from even closer.
Screen size is measured on the diagonal, in inches. Multiply it by 1.2 and by 2, and the two answers give you the range to place your sofa in.
Viewing distance by TV size
Samsung Singapore's buying guide, updated August 7, 2026, says to multiply the screen size by 1.2, so the screen fills about 40 degrees of your view. Samsung Canada's guide, updated April 29, 2026, works the other way: divide your viewing distance by 2 to get the screen size, which puts you at twice the diagonal. The table runs both rules for common sizes.
| TV size | Closer end (1.2 times) | Farther end (2 times) |
|---|---|---|
| 43-inch | 4.3 feet | 7.2 feet |
| 50-inch | 5 feet | 8.3 feet |
| 55-inch | 5.5 feet | 9.2 feet |
| 65-inch | 6.5 feet | 10.8 feet |
| 75-inch | 7.5 feet | 12.5 feet |
| 85-inch | 8.5 feet | 14.2 feet |
If your room is fixed, flip the math. Measure from the sofa to the TV wall in inches and divide by 2 to get the screen size that suits a relaxed setup. At 10 feet, or 120 inches, Samsung's example lands on a 60-inch TV.
Why a 4K TV lets you sit closer
Sharper screens hide their pixels at shorter distances. Sony's support guide recommends sitting 1.5 times the screen's height from a 4K TV and 3 times the height from an HD TV. For a 55-inch set, Sony lists 39 inches for 4K and 83 inches for HD. That is much closer than Samsung's range, so treat the 4K figure as a near limit for a sharp picture rather than a target.
How to measure from your sofa
Step 1: Find your screen size
Check the model number or the box. The size is the diagonal of the screen, not the width of the TV.
Step 2: Measure from where your head rests
Sit down and measure from your eyes to the screen, not from the front edge of the sofa. A deep sofa can move you back farther than you expect.
Step 3: Place the sofa inside the range
Use the table to find your screen size, then set the sofa between the two distances. Closer feels more like a theater. Farther back is easier for long evenings and for a room full of people.
Frequently asked questions
How far should I sit from a 65-inch TV?
About 6.5 to 10.8 feet. That is 1.2 to 2 times the screen size, the range Samsung's guides use.
Can you sit too close to a TV?
Yes, close enough that you keep turning your head to follow the action. Sony recommends 1.5 times the screen's height for 4K and 3 times for HD, and Samsung aims for the screen to fill about 40 degrees of your view.
What size TV fits a 10-foot viewing distance?
A 60-inch TV, by Samsung's rule of dividing the distance in inches by 2. For a more cinema-like feel, a larger screen works at the same distance.
