1179 × 2556 vs 1920 × 1080 and 1179 × 2556 vs 2560 × 1440
1179 × 2556 has 45% more pixels than 1080p (1920 × 1080). On a 6.7-inch phone that is 420 vs 329 pixels per inch, so text and fine detail look sharper at 1179 × 2556. A game or encoder has to process 1.45× as many pixels per frame, which costs frame rate on the same graphics card and, at equal quality, file size.
1440p (2560 × 1440) has 22% more pixels than 1179 × 2556. On a 6.7-inch phone that is 420 vs 438 pixels per inch, so text and fine detail look softer at 1179 × 2556. A game or encoder processes only 82% as many pixels per frame, which helps frame rates and keeps files smaller.

Pixel density (PPI) by screen size
Pixel density is the diagonal in pixels (2,815) 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).
| Device | Screen | PPI |
|---|---|---|
| iPhone 15 | 6.1 inches | 460 |
| iPhone 16 | 6.1 inches | 460 |
| Screen diagonal | PPI | Pixels blend at about |
|---|---|---|
| 6.1 inches | 461 | 7 in (19 cm) |
| 6.3 inches | 447 | 8 in (20 cm) |
| 6.7 inches | 420 | 8 in (21 cm) |
| 6.9 inches | 408 | 8 in (21 cm) |

How to resize to 1179 × 2556
- In an editor, set the sequence or export frame size to 1179 × 2556; 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=1179:2556 -c:a copy out.mp4 - With FFmpeg, keep the whole picture and add bars:
ffmpeg -i in.mp4 -vf "scale=1179:2556:force_original_aspect_ratio=decrease,pad=1179:2556:(ow-iw)/2:(oh-ih)/2" -c:a copy out.mp4 - Upscaling a smaller source to 1179 × 2556 makes the file bigger without adding detail; scale down from a larger master when you can.
