1080 × 2400 compared with common resolutions
| Resolution | Pixels | 1080 × 2400 has |
|---|---|---|
| 720p (1280 × 720) | 921,600 | 2.81× as many |
| 1080p (1920 × 1080) | 2,073,600 | 1.25× as many |
| 1440p (2560 × 1440) | 3,686,400 | 70% as many |

1080 × 2400 vs 1920 × 1080 and 1080 × 2400 vs 2560 × 1440
1080 × 2400 has 25% more pixels than 1080p (1920 × 1080). On a 6.7-inch phone that is 393 vs 329 pixels per inch, so text and fine detail look sharper at 1080 × 2400. A game or encoder has to process 1.25× as many pixels per frame, which costs frame rate on the same graphics card and, at equal quality, file size.
1440p (2560 × 1440) has 42% more pixels than 1080 × 2400. On a 6.7-inch phone that is 393 vs 438 pixels per inch, so text and fine detail look softer at 1080 × 2400. A game or encoder processes only 70% as many pixels per frame, which helps frame rates and keeps files smaller.

Where 1080 × 2400 is used
Phones grew taller after 2017 as bezels shrank. By around 2020, 20:9 Full HD+ panels at 1080 × 2400 were among the most common Android screens.
- One of the most common Android phone screens, from budget to upper mid-range: Full HD+ at 20:9.
- Screen recordings that are taller than 9:16, so they need cropping or bars for Reels and TikTok.
- Phone wallpapers for these screens.
Pixel density (PPI) by screen size
Pixel density is the diagonal in pixels (2,632) 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 |
|---|---|---|
| 6.1 inches | 431 | 8 in (20 cm) |
| 6.3 inches | 418 | 8 in (21 cm) |
| 6.7 inches | 393 | 9 in (22 cm) |
| 6.9 inches | 381 | 9 in (23 cm) |
Print sizes for a 1080 × 2400 image

Video at 1080 × 2400: 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 1080 × 2400 frame is 7.8 MB as 8-bit RGB, or 3.9 MB in the 8-bit 4:2:0 format video codecs work in. At 30 fps that is 933 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 | 864 × 1920 picture, 20% of the frame is bars | Keeps 80% of the picture (crops the height) |
| 16:9 (YouTube), 1920 × 1080 | 486 × 1080 picture, 75% of the frame is bars | Keeps 25% of the picture (crops the height) |
| 4:5 (feed portrait), 1080 × 1350 | 608 × 1350 picture, 44% of the frame is bars | Keeps 56% of the picture (crops the height) |
| 1:1 (square), 1080 × 1080 | 486 × 1080 picture, 55% of the frame is bars | Keeps 45% of the picture (crops the height) |

How to resize to 1080 × 2400
- In an editor, set the sequence or export frame size to 1080 × 2400; 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=1080:2400 -c:a copy out.mp4 - With FFmpeg, keep the whole picture and add bars:
ffmpeg -i in.mp4 -vf "scale=1080:2400:force_original_aspect_ratio=decrease,pad=1080:2400:(ow-iw)/2:(oh-ih)/2" -c:a copy out.mp4 - Upscaling a smaller source to 1080 × 2400 makes the file bigger without adding detail; scale down from a larger master when you can.
| Scale | Size | Pixels |
|---|---|---|
| 25% | 270 × 600 | 162,000 |
| 50% | 540 × 1200 | 648,000 |
| 75% | 810 × 1800 | 1,458,000 |
| 150% | 1620 × 3600 | 5,832,000 |
| 200% | 2160 × 4800 | 10,368,000 |
