## 16:9 resolutions in pixels

| Name | Width x height | Total pixels |
| --- | --- | --- |
| 360p | 640 x 360 | 230,400 |
| 480p | 854 x 480 | 409,920 |
| 720p (HD) | 1280 x 720 | 921,600 |
| 1080p (Full HD) | 1920 x 1080 | 2,073,600 |
| 1440p (QHD, 2K) | 2560 x 1440 | 3,686,400 |
| 2160p (4K UHD) | 3840 x 2160 | 8,294,400 |
| 4320p (8K) | 7680 x 4320 | 33,177,600 |

Width comes first. YouTube recommends these sizes for 16:9 uploads. 854 x 480 is rounded, because an exact 16:9 frame 480 pixels high is 853.33 pixels wide.

## Extended Definition

Read a size as width x height. 16 divided by 9 is about 1.78, so any frame about 1.78 times as wide as it is tall is 16:9. Both 1920 x 1080 and 3840 x 2160 have this shape, but 3840 x 2160 holds four times as many pixels. A larger export cannot add detail the recording never had.

YouTube's standard aspect ratio on a computer is 16:9, so long videos, gameplay and streams usually start here. To cut a vertical clip from a 16:9 video, crop around the subject or fit the whole frame inside a 9:16 canvas. Cropping removes the sides. Fitting keeps everything and leaves space above and below. Check moving subjects and on-screen text before you export, and avoid stretching the image to fill the frame.

## FAQ

### What is 16:9 in pixels?

16:9 has no single pixel size. Common resolutions are 1280 x 720 (720p), 1920 x 1080 (1080p), 2560 x 1440 (1440p) and 3840 x 2160 (4K UHD). Width comes first, and every pair has the same widescreen shape. Use the calculator on this page for another width or height.

### Is 1920x1080 16:9?

Yes. 1920 x 1080 is 16:9, because 1920 divided by 120 is 16 and 1080 divided by 120 is 9. To check another size, multiply its width by 9 and its height by 16. If the results match, the frame is exactly 16:9.

### Is 16:9 the same as 1080p or 4K?

No. 16:9 describes shape, while 1080p and 4K UHD describe resolution. Both 1920 x 1080 and 3840 x 2160 are 16:9. Choosing a larger export does not by itself add detail to a lower-resolution recording.

### What does 16:9 mean, and is it landscape or portrait?

16:9 means 16 units of width for every 9 units of height. It is landscape, also called widescreen, with a width about 1.78 times its height. The reversed ratio, 9:16, is portrait.

### How do I calculate 16:9 width and height?

Divide the width by 16 and multiply by 9 to get the height: 1920 ÷ 16 × 9 = 1080. To find the width, multiply the height by 16 and divide by 9. Video encoders can require even pixel dimensions, and the calculator on this page returns an exact 16:9 pair with even values.

### What is the difference between 16:9 and 9:16?

16:9 is horizontal and 9:16 is vertical. 1920 x 1080 is 16:9, and swapping the numbers to 1080 x 1920 gives 9:16 for full-screen short videos. Crop or fit the video when you convert it so faces and text do not stretch.

### How does the 16:9 calculator round dimensions?

It selects the nearest exact 16:9 size with even width and height for video encoding, so an unusual input can change slightly. The calculator returns dimensions. Use a resizing or upscaling tool to change an actual video file.
