8K Resolution Dimensions
8K UHD is 7680 pixels wide and 4320 pixels tall, a 16:9 aspect ratio with 33.2 million pixels, 16 times as many as 1080p. It is also called 4320p.
Is my screen 8K?
Turn on JavaScript to compare your screen with 8K. The check runs in your browser.
How sharp is 8K at each screen size?
8K at 24 in gives 367 pixels per inch, against 117 at 75 in. Beyond the distance shown, 20/20 vision cannot pick out single pixels.
Seen from a desk, 8K looks very sharp at every desk size from 24 to 43 in. On TVs from 55 in up, you sit further back, so the last column matters more. Every size here needs scaling, from 125% up to 300% on the 24 in screen.
Where is 8K used?
8K shows up mainly on large premium TVs and a few professional monitors. Very little film or TV is made in 8K, so most of what you watch is upscaled from 4K. To see the gain, you need a big screen and a seat close to it.
How does 8K compare with other resolutions?
8K has 16× the pixels of 1080p. Each row below divides its pixel count by the other resolution.
8K has about twice the pixels of 5K, the next step down. Nothing in our chart has more pixels.
What does 8K look like with display scaling?
Scaling keeps every pixel but draws text and windows bigger, so you get less desktop space. At 150%, 8K gives the room of 5120 × 2880 with the sharpness of 7680 × 4320.
Try any resolution and scale in the resolution scale calculator. Phones and Macs work the same way, with a pixel ratio of 2 or 3.
How do I set my screen to 8K?
On Windows, open Settings, then System, then Display, and pick 7680 × 4320 under Display resolution. On a Mac, open System Settings, then Displays.
You only see resolutions your screen and graphics card support. Pick your screen's native resolution, marked Recommended on Windows, or the picture looks soft.
How much data does 8K use?
One 8K frame holds 33,177,600 pixels, 100 MB before compression at 8 bits per color. At 60 frames a second that is 48 gigabits every second, and 115 at 144.
Streaming services and game consoles compress this heavily. Cables carry it uncompressed, so higher resolutions and refresh rates need newer HDMI or DisplayPort versions.

Does 8K look the same on every screen?
No. The pixel count is fixed, but the pixels get bigger as the screen gets bigger. The table above shows how sharp 8K looks at each size.
How we measure
Pixel density is the pixel diagonal, √(width² + height²), divided by the screen diagonal in inches. Single pixels vanish for 20/20 vision beyond 3438 ÷ PPI inches. Windows scaling is PPI ÷ 96, rounded to a 25% step.
