The distance between sofa and television

The classic rule said "two and a half times the screen diagonal". It was valid for old HD televisions whose low resolution required significant distance to avoid seeing pixels.

With modern 4K TVs, this rule is obsolete. The recommended distance for a 4K TV is between 1.5 and 2.5 times the diagonal, even 1.2 to 1.6 times for an immersive cinema experience.

Too far: you lose immersion and the screen appears small. Too close: eye fatigue.

Identify your screen diagonal in inches, multiply by 2.54 to get centimetres, then multiply by 1.5 and 2.5 for your distance range. Measure from the TV wall to the front of the sofa.

The centre of the screen must be at seated eye level: approximately 95-115 cm from the floor for a standard sofa and average-height person.

Common mistake: TV above the fireplace. Forces the gaze permanently upward, creating neck tension. Avoid absolutely unless the mantel is under 50 cm high.

Interior designers often hide the TV behind a sliding panel or treat it as a work of art when on (Samsung The Frame). The principle: the TV must not be the focal point when it is off.

For home cinema enthusiasts, distance can drop to 1.2× the diagonal for stronger immersion (40° viewing angle). Requires a dedicated room.

A sophisticated practice: separating the TV zone from the conversation zone. Main sofa for viewing, secondary seating perpendicular for conversation.
