3440 × 1440 compared with common resolutions
| Resolution | Pixels | 3440 × 1440 has |
|---|---|---|
| 720p (1280 × 720) | 921,600 | 5.38× as many |
| 1080p (1920 × 1080) | 2,073,600 | 2.39× as many |

3440 × 1440 vs 2560 × 1440 and 3440 × 1440 vs 3840 × 2160
3440 × 1440 has 34% more pixels than 1440p (2560 × 1440). On a 34-inch screen that is 110 vs 86 pixels per inch, so text and fine detail look sharper at 3440 × 1440. A game or encoder has to process 1.34× as many pixels per frame, which costs frame rate on the same graphics card and, at equal quality, file size.
4K UHD (3840 × 2160) has 67% more pixels than 3440 × 1440. On a 32-inch screen that is 117 vs 138 pixels per inch, so text and fine detail look softer at 3440 × 1440. A game or encoder processes only 60% as many pixels per frame, which helps frame rates and keeps files smaller.

Where 3440 × 1440 is used
3440 × 1440 became the mainstream ultrawide resolution in the mid-2010s on 34-inch curved monitors. Its 43:18 ratio (2.39:1) matches scope cinema, and it has about 4.95 million pixels, 2.4 times 1080p.
- The common 34-inch ultrawide monitor resolution (exactly 43:18, sold as 21:9).
- Ultrawide gameplay capture, which needs cropping or reframing for 16:9 and 9:16.
- Productivity setups that replace two monitors.
Pixel density (PPI) by screen size
Pixel density is the diagonal in pixels (3,729) 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 | 129 | 27 in (68 cm) |
| 34 inches | 110 | 31 in (80 cm) |
| 38 inches | 98 | 35 in (89 cm) |

Video at 3440 × 1440: bitrate and file size
| Frame rate | Bitrate | Per minute | Per 10 minutes |
|---|---|---|---|
| 24-30 fps | 16 Mbps | about 120 MB | about 1200 MB |
| 48-60 fps | 24 Mbps | about 180 MB | about 1800 MB |
Uncompressed, one 3440 × 1440 frame is 14.9 MB as 8-bit RGB, or 7.4 MB in the 8-bit 4:2:0 format video codecs work in. At 30 fps that is 1,783 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 × 452 picture, 76% of the frame is bars | Keeps 24% of the picture (crops the width) |
| 16:9 (YouTube), 1920 × 1080 | 1920 × 804 picture, 26% of the frame is bars | Keeps 74% of the picture (crops the width) |
| 4:5 (feed portrait), 1080 × 1350 | 1080 × 452 picture, 67% of the frame is bars | Keeps 33% of the picture (crops the width) |

How to resize to 3440 × 1440
- In an editor, set the sequence or export frame size to 3440 × 1440; 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=3440:1440 -c:a copy out.mp4 - With FFmpeg, keep the whole picture and add bars:
ffmpeg -i in.mp4 -vf "scale=3440:1440:force_original_aspect_ratio=decrease,pad=3440:1440:(ow-iw)/2:(oh-ih)/2" -c:a copy out.mp4 - Upscaling a smaller source to 3440 × 1440 makes the file bigger without adding detail; scale down from a larger master when you can.
| Scale | Size | Pixels |
|---|---|---|
| 25% | 860 × 360 | 309,600 |
| 50% | 1720 × 720 | 1,238,400 |
| 75% | 2580 × 1080 | 2,786,400 |
| 150% | 5160 × 2160 | 11,145,600 |

Frequently asked questions
Is 3440×1440 2K or 4K?
Neither, strictly. 3440×1440 is an ultrawide 1440p frame. It is often sold as "2K", but cinema 2K is 2048×1080; 4K UHD (3840×2160) has 1.67× as many pixels.
What aspect ratio is 3440×1440?
43:18 exactly (2.3889), within 1% of 21:9 (ultrawide), so it fits a 21:9 (ultrawide) frame with a tiny crop or thin bars.
What bitrate should a 3440×1440 video use for YouTube?
YouTube recommends 16 Mbps at 24-30 fps and 24 Mbps at 48-60 fps for its 1440p (2K) tier (SDR). That is about 120 MB per minute at standard frame rates, before audio.
How does 3440×1440 compare with 1080p?
It has 2.39× the pixels of 1920×1080 (4,953,600 vs 2,073,600). Encoding time and file size at equal quality scale roughly with pixel count.
What is 3440×1440 resolution called?
3440 × 1440 is also called ultrawide QHD, UWQHD, 21:9 1440p. The common ultrawide monitor resolution, and a common screen-recording source.
How many megapixels is 3440×1440?
4,953,600 pixels, which is 4.95 megapixels. A 12-megapixel phone photo (4032 × 3024) has 2.5× as many.
How big can I print a 3440×1440 image?
At 300 DPI, the usual photo-print target, 11.5 × 4.8 inches (29.1 × 12.2 cm). At 150 DPI, fine for posters viewed from a distance, twice that: 22.9 × 9.6 inches.
