Quick answer
For comfortable viewing, sit about 1.5–2.5 times the screen size away from a 4K TV, and 2.5–3.5 times from a Full HD TV. If your sofa is 8 ft (96 inches) from the wall, a 43–65 inch 4K TV works, with 55 inches a popular middle choice. A 43 inch 4K TV suits a bedroom 5–6 ft away.
How to use this calculator
- Measure from your eyes on the sofa to the wall where the TV will go.
- Choose 4K or Full HD.
- Pick a size in the recommended range that fits your wall and budget.
