What is the 8K resolution size?

8K resolution is 7680 pixels wide by 4320 pixels tall. Its physical screen size is not fixed: the same 7680 x 4320 grid works out to about 275 PPI on a 32-inch monitor and about 136 PPI on a 65-inch TV.

How many pixels is 8K resolution?

7680 x 4320 = 33,177,600 pixels, or about 33.2 megapixels per frame. That is exactly four times the 8,294,400 pixels of 4K UHD and sixteen times the 2,073,600 pixels of 1080p.

What resolution is 7680x4320?

7680 x 4320 is 8K UHD (also called UHD-2). Its aspect ratio is 16:9, because 7680 ÷ 480 = 16 and 4320 ÷ 480 = 9, and each axis is exactly double 4K UHD (3840 x 2160).

Which standard defines 8K?

ITU-R Recommendation BT.2020 lists 7680 × 4320 and 3840 × 2160 as the two UHDTV image formats, both 16:9 with square pixels, with frame rates from 23.976 to 120 Hz and 10- or 12-bit coding. SMPTE ST 2036-1 carries the same raster for production.

What bitrate should I use for 8K video?

Bitrate depends on the destination, frame rate, dynamic range and codec. For YouTube SDR uploads, the current official guidance is 80–160 Mbps at 24–30 fps and 120–240 Mbps at 48–60 fps. YouTube lists 100–200 Mbps and 150–300 Mbps respectively for HDR uploads. These are upload recommendations, not universal streaming or camera-recording requirements.

How much storage does one hour of 8K video take?

Size = bitrate × seconds ÷ 8. At 100 Mbps, 100 × 3,600 ÷ 8 = 45,000 MB, or 45 GB per hour; at 200 Mbps it is 90 GB. Uncompressed 10-bit 4:2:2 8K at 30 fps runs at about 19.9 Gbps, roughly 9 TB per hour, which is why cameras record compressed raw or intra-frame codecs.

How close do you need to sit to see the difference between 8K and 4K?

With 20/20 acuity (one arcminute) individual 8K pixels blend together beyond about 0.39 times the screen diagonal, and 4K pixels beyond about 0.78 times. On a 65-inch TV that is about 2 ft 1 in for 8K and 4 ft 3 in for 4K, so 8K only adds visible detail closer than roughly 4 ft. Content, scaling and eyesight also matter.

What HDR standards are used with 8K?

8K displays support the same HDR ecosystem as 4K: HDR10 (open standard, 10-bit, static metadata), HDR10+ (dynamic metadata), Dolby Vision (dynamic metadata, 12-bit capable), and HLG (broadcast-friendly). HDR signals use BT.2100 transfer functions on BT.2020 color primaries.

Is an 8K file always four times larger than 4K?

No. 8K has exactly four times the pixels, but file size is set by bitrate and duration. YouTube recommends 80–160 Mbps for 8K at 30 fps against 35–45 Mbps for 4K, roughly two to four times higher, and efficient codecs such as HEVC or AV1 narrow the gap further.

Is every resolution near 8,000 pixels wide the same format?

No. This page uses 8K UHD at 7680 x 4320 and 16:9. Cinema and camera rasters such as 8192 × 4320 are also sold as 8K, so check the exact width, height and aspect ratio rather than relying on the label alone.

20/20 acuity distance

Video size (decimal)

PPI = √(width² + height²) ÷ diagonal. The acuity distance is where one pixel subtends one arcminute; sitting farther away, a 20/20 eye cannot separate adjacent pixels, so extra resolution adds no visible detail. File size = bitrate × duration ÷ 8, excluding audio and container overhead.

Quick answer

8K resolution size is 7680 x 4320 pixels: 7,680 wide by 4,320 tall, 33,177,600 pixels in total (about 33.2 megapixels), at a 16:9 aspect ratio. That is four times 4K UHD (3840 x 2160) and sixteen times 1080p.

8K screen size	Pixel density
32-inch monitor	275.4 PPI

Summary

8K Ultra HD uses a frame size of 7680 x 4320 pixels — exactly 33,177,600 pixels per frame — at a 16:9 aspect ratio, as defined for UHDTV in ITU-R BT.2020. That is four times the pixel count of 4K UHD and sixteen times 1080p Full HD. This page calculates PPI, the 20/20 viewing distance at which 8K detail stops being resolvable, and bitrate-based storage, lists official YouTube 8K upload bitrates, and compares 8K with 30 other resolutions in a sourced table you can search, sort and download.

How it works

Read the spec card at the top to get the essential 8K numbers at a glance.
Enter a screen diagonal to get the pixel density (PPI) and the distance at which one pixel subtends one arcminute (20/20 acuity).
Enter a bitrate and duration for a decimal-GB file size, or change the width and height to analyze any other resolution against 8K.
Search or sort the resolution table to compare 8K with 30 display, video and cinema formats, or download it as CSV.
Click any row in the Copy Spec panel to copy that value directly to your clipboard.

Use cases

Choosing an export resolution for 8K-capable video platforms and future-proof archival.
Verifying pixel density (PPI) for an 8K monitor or TV before purchase.
Working out how close you must sit to an 8K TV to see more detail than 4K.
Setting FFmpeg, DaVinci Resolve, or other NLE encoding parameters for 8K output.
Comparing storage requirements across 1080p, 4K, and 8K for a production project.
Planning bandwidth and CDN infrastructure for an 8K live stream or VOD service.
Confirming whether a camera, capture card, or display truly supports 8K before purchase.
