|---|---|---|
| 720p (1280 × 720) | 921,600 | 3.00× as many |

2560 × 1080 vs 1920 × 1080 and 2560 × 1080 vs 2560 × 1440
2560 × 1080 has 33% more pixels than 1080p (1920 × 1080). On a 34-inch screen that is 82 vs 65 pixels per inch, so text and fine detail look sharper at 2560 × 1080. A game or encoder has to process 1.33× as many pixels per frame, which costs frame rate on the same graphics card and, at equal quality, file size.
1440p (2560 × 1440) has 33% more pixels than 2560 × 1080. On a 34-inch screen that is 82 vs 86 pixels per inch, so text and fine detail look softer at 2560 × 1080. A game or encoder processes only 75% as many pixels per frame, which helps frame rates and keeps files smaller.

Where 2560 × 1080 is used
21:9 monitors appeared in the early 2010s, marketed as cinema-shaped because wide films are about 2.39:1. The actual ratio of 2560 × 1080 is 64:27 (2.37:1), which is why wide films fill it almost exactly while 16:9 video shows bars at the sides.
- 29-inch ultrawide monitors, sold as 21:9 (exactly 64:27).
- Gameplay and screen recordings that become a thin strip in a vertical feed.
- Cinematic "scope" edits for YouTube, which shows them letterboxed in its 16:9 player.
Pixel density (PPI) by screen size
Pixel density is the diagonal in pixels (2,778) divided by the screen diagonal in inches. The last column is the distance at which a person with normal vision stops seeing individual pixels (one arcminute of visual acuity).
| Screen diagonal | PPI | Pixels blend at about |
|---|---|---|
| 29 inches | 96 | 36 in (91 cm) |
| 34 inches | 82 | 3.5 ft (1.1 m) |
| 38 inches | 73 | 3.9 ft (1.2 m) |

Video at 2560 × 1080: bitrate and file size
| Frame rate | Bitrate | Per minute | Per 10 minutes |
|---|---|---|---|
| 24-30 fps | 8 Mbps | about 60 MB | about 600 MB |
| 48-60 fps | 12 Mbps | about 90 MB | about 900 MB |
Uncompressed, one 2560 × 1080 frame is 8.3 MB as 8-bit RGB, or 4.1 MB in the 8-bit 4:2:0 format video codecs work in. At 30 fps that is 995 Mbps of raw video, which is why every delivery format compresses it.

How the frame lands in each common shape, either fitted whole with bars or scaled up to fill and cropped:
| Target frame | Fit with bars | Fill and crop |
|---|---|---|
| 9:16 (TikTok, Reels, Shorts), 1080 × 1920 | 1080 × 456 picture, 76% of the frame is bars | Keeps 24% of the picture (crops the width) |
| 16:9 (YouTube), 1920 × 1080 | 1920 × 810 picture, 25% of the frame is bars | Keeps 75% of the picture (crops the width) |
| 4:5 (feed portrait), 1080 × 1350 | 1080 × 456 picture, 66% of the frame is bars | Keeps 34% of the picture (crops the width) |

How to resize to 2560 × 1080
- In an editor, set the sequence or export frame size to 2560 × 1080; if the source has a different shape, choose scale to fill (crop) or scale to fit (bars) rather than stretch.
- With FFmpeg, exact size:
ffmpeg -i in.mp4 -vf scale=2560:1080 -c:a copy out.mp4 - With FFmpeg, keep the whole picture and add bars:
ffmpeg -i in.mp4 -vf "scale=2560:1080:force_original_aspect_ratio=decrease,pad=2560:1080:(ow-iw)/2:(oh-ih)/2" -c:a copy out.mp4 - Upscaling a smaller source to 2560 × 1080 makes the file bigger without adding detail; scale down from a larger master when you can.
| Scale | Size | Pixels |
|---|---|---|
| 25% | 640 × 270 | 172,800 |
| 50% | 1280 × 540 | 691,200 |
| 75% | 1920 × 810 | 1,555,200 |
| 150% | 3840 × 1620 | 6,220,800 |
| 200% | 5120 × 2160 | 11,059,200 |
