A 77-inch TV is 68 inches wide.

TV sizes are diagonals — the one number that tells you nothing about the wall. Real panel dimensions, the distance rule, and the stand math, in inches.

01

Real panel dimensions

Panels are 16:9, so width ≈ 87% of the diagonal and height ≈ 49%. Bezels add fractions of an inch, no more. These are the numbers to hold against the wall — and against the console beneath.

Size (diagonal)Panel W × HComfortable sofa distance
55″48 × 275½ – 7 ft
65″57 × 326½ – 9 ft
75″66 × 377½ – 10 ft
77″68 × 387½ – 10 ft
85″74 × 428½ – 11 ft

Distance = 1.2–1.6 × the diagonal for 4K. Closer than 1.2× and you're watching pixels; past 1.6× the 85″ was wasted money.

02

Stand or wall?

  • The stand should outrun the TV. A 65″ panel (57″ wide) on a 58″ stand is at its limit; the 70″ stand carries it with margin. Media consoles run 58–80″ wide × 16–17″ deep — that depth is real floor.
  • Wall-mounting gives the floor back: a mounted panel projects ~3″. In a tight room, that's the difference that unlocks the walkway.
  • Height: seated eye level hits the center of the screen — center ≈ 42″ off the floor for sofa viewing. Higher only over a fireplace, and your neck will file a complaint.
  • Glare check: note which windows face the panel on your plan — the afternoon sun doesn't care what you paid for OLED.

The room does the choosing

57″ panel (a "65-inch" TV) ≈ 8 ft sofa 84 × 38
sofa-to-wall distance picks the size — not the other way around

Measure sofa-front to TV-wall on your plan, divide by 1.4, and you have the diagonal the room wants. An 8-foot gap says 65–70″; the 85″ wants nine feet and change. If the sofa can't move back, the TV size was never really your decision.

Check the throw on your plan.

Poché's wall-TV stencils are true panel widths — drop one on your plan, measure the throw to the sofa, and buy the size the room asked for.
