What 1280x720 is
The lower of the two original HDTV formats and the floor for anything described as high definition. It is still a common upload resolution because it encodes cheaply: a ninth of the pixels of 4K, and 44% of a 1080p frame.

| Compared with 4K UHD | 0.11× the pixels |
Pixel density at common screen sizes
A resolution on its own says nothing about sharpness — the same 1280x720 panel is dense on a laptop and coarse on a television. Density is the diagonal in pixels divided by the diagonal in inches.
| Diagonal | Pixel density | |
|---|---|---|
| 13.3 in | 110 PPI | Comfortable at native size |
| 15.6 in | 94 PPI | Coarse — individual pixels are visible at desk distance |
| 24 in | 61 PPI | Coarse — individual pixels are visible at desk distance |
| 27 in | 54 PPI | Coarse — individual pixels are visible at desk distance |
| 32 in | 46 PPI | Coarse — individual pixels are visible at desk distance |

Frequently asked questions
What is the aspect ratio of 1280x720?
16:9.
How many pixels is 1280x720?
921,600 pixels, or 0.92 megapixels.
Is 1280x720 higher resolution than 1080p?
It has 44% of the pixels of a 1920×1080 frame.
What size screen suits 1280x720?
Pixel density is what decides that. 110 PPI at 13.3 in, 94 PPI at 15.6 in, 61 PPI at 24 in, 54 PPI at 27 in, 46 PPI at 32 in. Below roughly 110 PPI text starts to look coarse; above about 200 the operating system will usually scale the interface rather than render it at native size.
