What 2560x1440 is
Four times the pixels of 720p and the resolution that has become the desktop default, because at 27 inches it lands near 109 PPI — sharp enough without needing display scaling, which 4K at that size does.

Pixel density at common screen sizes
A resolution on its own says nothing about sharpness — the same 2560x1440 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 | 221 PPI | High density — the OS will scale the interface |
| 15.6 in | 188 PPI | Sharp |
| 24 in | 122 PPI | Comfortable at native size |
| 27 in | 109 PPI | Comfortable at native size |
| 32 in | 92 PPI | Coarse — individual pixels are visible at desk distance |

Frequently asked questions
What is the aspect ratio of 2560x1440?
16:9.
How many pixels is 2560x1440?
3,686,400 pixels, or 3.69 megapixels.
Is 2560x1440 higher resolution than 1080p?
It has 1.78× as many pixels as a 1920×1080 frame.
What size screen suits 2560x1440?
Pixel density is what decides that. 221 PPI at 13.3 in, 188 PPI at 15.6 in, 122 PPI at 24 in, 109 PPI at 27 in, 92 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.
