5K Resolution Dimensions
5K is 5120 pixels wide and 2880 pixels tall, a 16:9 aspect ratio with 14.7 million pixels, 7.1 times as many as 1080p.
Is my screen 5K?
Turn on JavaScript to compare your screen with 5K. The check runs in your browser.
How sharp is 5K at each screen size?
5K at 24 in gives 245 pixels per inch, against 78 at 75 in. Beyond the distance shown, 20/20 vision cannot pick out single pixels.
Seen from a desk, 5K looks very sharp at 24 to 32 in and crisp at 43 in. On TVs from 55 in up, you sit further back, so the last column matters more. Windows stays at 100% from 55 in up, while the 24 in screen needs 250%.
Where is 5K used?
5K is found mostly on 27 inch monitors made for Mac users and photo editors. At that size it doubles 1440p in each direction, so the desktop looks like 1440p with very crisp text. Few games run at 5K, as the pixel count is heavy work for a graphics card.
How does 5K compare with other resolutions?
5K has 7.1× the pixels of 1080p. Each row below divides its pixel count by the other resolution.
5K has about three quarters more pixels than 4K, the next step down. 8K, the next step up, has about twice the pixels of 5K.
What does 5K look like with display scaling?
Scaling keeps every pixel but draws text and windows bigger, so you get less desktop space. At 150%, 5K gives the room of 3413 × 1920 with the sharpness of 5120 × 2880.
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 5K?
On Windows, open Settings, then System, then Display, and pick 5120 × 2880 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 5K use?
One 5K frame holds 14,745,600 pixels, 44 MB before compression at 8 bits per color. At 60 frames a second that is 21 gigabits every second, and 51 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.

How many pixels is 5K?
5K is 5120 × 2880, which is 14,745,600 pixels in total. That is 14.7 megapixels.
What screen size suits 5K?
On a 24 in screen, 5K gives 245 pixels per inch, and on 75 in it gives 78. Smaller screens look sharper, so pick the size for how far away you sit.
What is 5K at 150% scaling?
A desktop space of 3413 × 1920. Every item is drawn 1.5 times bigger, using all 5120 × 2880 pixels, so text stays as sharp as the panel allows.
How much data is one 5K frame?
44 MB before compression, at 8 bits per color. At 60 frames a second that is 21 gigabits every second, which is why video is compressed.
Does 5K 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 5K 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.
