65-inch and 77-inch screens at the same scale: the 77-inch is 10.5 in wider, 5.9 in taller and has 40% more area.

Short answer

A 77-inch OLED is 67.1 in × 37.8 in of picture against 56.7 in × 31.9 in for a 65-inch: 10.4 in wider, 5.9 in taller and 40% more screen. Choose 77 inches if your eyes are about 8 ft or more from the screen and you have about 68 in of wall; 65 inches if you sit under about 7.5 ft. The 77-inch weighs 15 lb more in LG’s C5 (51.8 vs 36.6 lb) and 29–30 lb more in Samsung’s S90F and S90H, which also move to a larger VESA pattern.

Key takeaways

40% more picture: a 77-inch at 9 ft looks like a 65-inch at 7.6 ft.
77 inches is the OLED answer to 75-inch LCDs; there are no 75-inch OLEDs.
Sweet spots: 6 ft 6 in–8 ft 10 in (65) and 7 ft 8 in–10 ft 5 in (77).
Same panel, inputs and features within each line; the decision is size and weight.

For OLED buyers, the step up from 65 inches isn’t 75: it’s 77. That makes the jump bigger (40% more picture rather than 33%) and, for some lines, heavier than you might expect.

What the extra 40% feels like

65-inch and 77-inch screens at the same scale: the 77-inch is 10.5 in wider, 5.9 in taller and has 40% more area.

A 77-inch at 9 ft fills the same share of your view as a 65-inch at 7.6 ft. By eyes-to-screen distance:

Under 6.5 ft: a 65-inch already fills 40°; the 77-inch is too much for most people.
6.5–7.5 ft: 65 inches is in its sweet spot.
7.5–9 ft: both work; the 77-inch is noticeably more cinematic.
9–10.5 ft: a 65-inch drifts below 30°; the 77-inch is in its sweet spot.

Weight and mounting

Line	65-inch	77-inch	VESA 65 → 77
LG C5	OLED65C5PUA: 36.6 lb	OLED77C5PUA: 51.8 lb	300 × 200 → 300 × 200
Samsung S90H	42.1 lb	71.4 lb	300 × 200 → 400 × 300
Samsung S90F	46.7 lb	76.7 lb	300 × 200 → 400 × 300

LG’s C5 stays light and keeps the same VESA pattern, so the same wall mount may work for both (check its weight rating). Samsung’s 77-inch OLEDs gain about 30 lb and need a mount with 400 × 300 mm holes.

Picture and features

Within each line, the 65- and 77-inch share panel type, processing, HDR formats and inputs. The 77-inch’s pixels are larger, but at the distances where it makes sense (8 ft and up), 4K detail is still finer than 20/20 vision resolves. Price is the bigger difference: large OLEDs cost considerably more per inch than Mini LEDs of similar size.

Our take

Get the 77-inch if you sit 8 ft or more away, have about 68 in of wall and a mount or stand rated for it.
Stay at 65 if you sit within about 7.5 ft, or the budget would be better spent on a better 65-inch line.

Frequently asked questions

How much bigger is a 77-inch TV than a 65-inch?

40% more screen area (2,533 sq in vs 1,805 sq in), 10.4 in wider and 5.9 in taller.

Is a 77-inch OLED worth it over 65?

If you sit 8 ft or more from the screen, usually yes: at 9 ft a 65-inch fills only about 30° of your view, a 77-inch about 35°. Under 7.5 ft, the 65-inch is the comfortable size.

How heavy is a 77-inch OLED?

51.8–76.7 lb without the stand among the models we list: LG C5 51.8 lb, Samsung S90H 71.4 lb, S90F 76.7 lb.

Why are there 77-inch OLEDs but no 75-inch?

The two OLED panel makers, LG Display and Samsung Display, produce 77-inch panels rather than 75-inch ones, while LCD panel makers standardized on 75. TV brands can only sell the sizes the panel makers produce.
