Introduction
Since video streaming has become an inseparable part of entertainment, technological advancements for digital display and digital content recorders have evolved significantly. 8K resolution is another offspring of the latest video streaming technology to upscale your streaming experience with more pixelization in perfection. So, before investing in any 8K quality video production, execution, or streaming, let's get a comprehensive guide on what resolution 8K means in the streaming world.
What is 8K Resolution?
There are two types of resolution: digital image resolution and digital display resolution. People often get confused between these two resolutions as both are measured and defined by the same unit, PPl (Pixels Per Inch).
Now, 8K resolution refers to both digital image and digital display resolution. Here, 8K resolution is applicable for both devices: one device that records video in 8K, such as a camera or smartphone, and another one that displays your recorded video on screen in 8K, such as a TV or monitor.
What 8K Resolution Stands for?
8K resolution contains three elements: 8, which refers to the number of horizontal pixels around 8000 on the display screen; 8K, which refers to the resolution designing unit Kilo(1000); and resolution, which refers to the number of pixels on a specific area of the display screen.
For example, if there is a single pixel in a particular space of FHD resolution, in 4K resolution, there will be four pixels in that same space, and in 8K, the same space will be filled up with sixteen pixels as 8K offers four times more pixels than 4K.
That means a particular area of the display screen is densely packed with more pixels. Now, more pixels mean more detailed information on each video frame, and that leads to clearer, smoother, and sharper video images.
What is the 8K Resolution Size?
When 8K resolution is all about filling up the gaps in a particular area on the display screen with more pixels, then it's important to know how many pixels are used in 8K resolution. In short, what is the 8K resolution size? Now, to understand the pixels’ depth and density of the 8K resolution as compared to the 4K or 1080p resolution, you must look at the comparison table below.
| Resolution Dynamics | 8K | 4K | 1080p |
| Pixel Per Inch | 117 | 59 | 29 |
| Pixels’ Density ( Horizontal × Vertical) | 7680(H) × 4320(V) | 3840(H) × 2160(V) | 1920(H) × 1080(V) |
| Pixel Size | 33.2 MP | 8.3MP | 2.1MP |
| Aspect Ratio | 16:9 | 16:9 | 16:9 |
| Frame Rate | Upto 120fps | Upto 60fps | Upto 60fps |
| Viewing Angle | 100 Degree | 55 Degree | 30-40 Drgree |
| Best For | Watching movies in theaters, medical & scientific imaging, post-production workflow | Video editing, streaming digital movies, playing video games with high digital graphics & texture | Video games, streaming online content |
Forms of 8K Resolution
8K comes in two primary forms:
8K UHD (Ultra High Definition): Designed for modern TVs and monitors with a 16:9 aspect ratio (7680 × 4320 pixels).
8K DCI (Digital Cinema Initiatives): Tailored for theater screens, offering a 256:135 aspect ratio (8192 × 4320 pixels).
Advantages & Disadvantages of 8K Resolution
Despite being an ultra-high-definition video quality, 8K resolution is very new in the video streaming industry. Therefore, while it has lots of advantages, it also has some challenges that stop 8K resolution from reaching the masses. So, let's look at the parameters that make 8K resolution demanding and challenging to its users.
Advantages
Crystal-clear and vibrant image, ideal for large screens or theaters
Enhanced detail for precision in video editing
Stunning results with zoom-in effects
Consistent image quality from all viewing angles
Beneficial for scientific and medical imaging with improved clarity
Provides a top-tier gaming experience with sharper visuals and crisp footage
Supports HDR, 360° videos, Wide Color Gamut (WCG), and fast refresh rates
Disadvantages
Limited 8K content available
Expensive 8K displays and recording devices
8K video files are four times larger than 4K, requiring more storage and bandwidth (20 to 50 Mbps)
Most streaming platforms don’t support 8K, except a few like YouTube and Vimeo
No Blu-ray discs available in 8K
Challenges of 8K Resolution
Adopting 8K faces two significant hurdles:
Cost: 8K devices for recording and display are prohibitively expensive for most users.
Content Scarcity: Very few platforms or creators currently produce content in 8K.
Editing or producing high-quality content also requires robust hardware, which isn't widely accessible.

Yes, 8K is worth it for professional uses, such as film production, video editing, or high-end viewing experiences. It provides unmatched detail and clarity, especially on larger screens, making it ideal for future-proofing content and delivering an ultra-realistic visual experience.
Can I watch 8K content on a 4K TV?
Yes, you can watch 8K content on a 4K TV, but you won’t experience the full benefits of 8K resolution. The 4K TV will downscale the content to match its resolution, so while the video will still be high-quality, it won't offer the level of detail that a true 8K display can provide.
What Screen Size is Suitable for 8K?
To get the maximum visual satisfaction from8K resolution, you must use a larger screen size. The best size is 77 inches or 88 inches. 8K is especially suitable for a wide TV screen.
