What 1366x768 is
For years the most common laptop panel in the world, and still one of the most common resolutions in web analytics. It is not quite 16:9 — 1366/768 is 1.779, not 1.778 — because 1365.33 is not a whole number of pixels.
The numbers
| Width | 1,366 px |
| Height | 768 px |
| Aspect ratio | 16:9 (nearest — the exact reduction is not a standard shape) |
| Total pixels | 1,049,088 |
| Megapixels | 1.05 MP |
| Compared with 1080p | 0.51× the pixels |
| Compared with 4K UHD | 0.13× the pixels |
What 1366x768 costs to move and to store
A frame is width × height × three bytes of colour, before any compression touches it. At 1366 × 768 that is 3.15 MB per frame, and video is frames per second:
| Frame rate | Uncompressed | An hour of it |
|---|---|---|
| 24 fps | 76 MB/s | 0.27 TB |
| 30 fps | 94 MB/s | 0.34 TB |
| 60 fps | 189 MB/s | 0.68 TB |
| 120 fps | 378 MB/s | 1.36 TB |
Nobody ships that. It is the number codecs exist to get away from — a streamed 1366x768 feed runs at a few tens of megabits, which is a compression ratio of several hundred to one, and it is why a still frame from a stream looks worse than a photograph of the same scene.
How close you have to sit for 1366x768 to be worth it
The eye resolves about one arcminute of detail. Past a certain distance the pixels merge whatever the panel does, and a higher resolution stops being visible rather than stopping being better. That distance is the pixel pitch divided by the tangent of one arcminute:
| Screen | Pixels merge beyond |
|---|---|
| 13.3 in monitor or laptop | 0.74 m (2.4 ft) |
| 15.6 in monitor or laptop | 0.87 m (2.9 ft) |
| 24 in monitor or laptop | 1.34 m (4.4 ft) |
| 27 in monitor or laptop | 1.5 m (4.9 ft) |
| 32 in monitor or laptop | 1.78 m (5.8 ft) |
| 43 in television | 2.4 m (7.9 ft) |
| 55 in television | 3.06 m (10.1 ft) |
| 65 in television | 3.62 m (11.9 ft) |
| 75 in television | 4.18 m (13.7 ft) |
Sitting further back than the figure for your screen, 1366x768 and the next resolution down look the same. That is the whole argument about 4K televisions in ordinary living rooms: the resolution is real and the seating position usually is not close enough to show it.
Pixel density at common screen sizes
A resolution on its own says nothing about sharpness — the same 1366x768 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 | 118 PPI | Comfortable at native size |
| 15.6 in | 100 PPI | Coarse — individual pixels are visible at desk distance |
| 24 in | 65 PPI | Coarse — individual pixels are visible at desk distance |
| 27 in | 58 PPI | Coarse — individual pixels are visible at desk distance |
| 32 in | 49 PPI | Coarse — individual pixels are visible at desk distance |

Frequently asked questions
What is the aspect ratio of 1366x768?
16:9 — approximately. 1366×768 does not reduce to a tidy ratio, so it is very slightly off the standard shape.
How many pixels is 1366x768?
1,049,088 pixels, or 1.05 megapixels.
Is 1366x768 higher resolution than 1080p?
1366x768 has 51% of the pixels of a 1920×1080 frame.
What size screen suits 1366x768?
Pixel density is what decides that. 118 PPI at 13.3 in, 100 PPI at 15.6 in, 65 PPI at 24 in, 58 PPI at 27 in, 49 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.
