**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), **21–26 lb more** in the Samsung S95F and LG G5, 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.

|  | 65-inch | 77-inch | Difference |
|---|---|---|---|

| Screen height | 31.9 in | 37.8 in | +5.9 in |
| Screen area | 1,805 sq in | 2,533 sq in | +40% |
| Whole TV width (models we list) | 56.5–57.4 in | 67.4–67.7 in |  |
| Weight without stand (models we list) | 36.6–59.7 lb | 51.8–76.7 lb |  |
| Immersive distance (40°) | 6 ft 6 in | 7 ft 8 in |  |
| Relaxed distance (30°) | 8 ft 10 in | 10 ft 5 in |  |

## What the extra 40% feels like

(Diagram: 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](/tv/oled65c5pua/): 36.6 lb | [OLED77C5PUA](/tv/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 |
| Samsung S95F | 41.7 lb | 62.2 lb | 400 × 300 → 400 × 300 |
| LG G5 | 48.5 lb | 74.1 lb | 300 × 300 → 300 × 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). The G5 and S95F also keep their patterns but gain 21–26 lb; the G5 ships with a wall bracket rather than a stand at both sizes. Samsung's 77-inch S90F and S90H 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.

Not set on OLED? A 75-inch Mini LED is cheaper per inch: see [best 75-inch TVs](/best-75-inch-tv/) and [65 vs 75 inch](/65-vs-75-inch-tv/).

## 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 S95F 62.2 lb, S90H 71.4 lb, LG G5 74.1 lb, Samsung 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.
