Pixel density at common screen sizes
A resolution on its own says nothing about sharpness — the same 4096x2160 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 | 348 PPI | High density — the OS will scale the interface |
| 15.6 in | 297 PPI | High density — the OS will scale the interface |
| 24 in | 193 PPI | Sharp |
| 27 in | 172 PPI | Sharp |
| 32 in | 145 PPI | Sharp |

Frequently asked questions
What is the aspect ratio of 4096x2160?
256:135 — approximately. 4096×2160 does not reduce to a tidy ratio, so it is very slightly off the standard shape.
How many pixels is 4096x2160?
8,847,360 pixels, or 8.85 megapixels.
Is 4096x2160 higher resolution than 1080p?
It has 4.27× as many pixels as a 1920×1080 frame.
What size screen suits 4096x2160?
Pixel density is what decides that. 348 PPI at 13.3 in, 297 PPI at 15.6 in, 193 PPI at 24 in, 172 PPI at 27 in, 145 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.
