All standard HD resolutions share a {{ratio|16|9}} aspect ratio, although some derived resolutions with smaller or larger ratios also exist, e.g. {{ratio|4|3}} and {{ratio|64|27}}, respectively. Most of the narrower resolutions are only used for storing, not for displaying videos, while the wider resolutions are often available as physical displays. YouTube, for instance, recommends users upload videos<ref name="YouTube">{{cite web|url=https://support.google.com/youtube/answer/6375112|publisher=Google|website=YouTube Help|title=Video resolution & aspect ratios| access-date = 2024-05-04}}</ref> in a 16:9 format with any of 240, 360, 480 (SD), 720, 1080 (HD), 1440, 2160 (4K) or 4320 (8K) lines.
 
While the monikers for those resolutions originally all used a letter prefix with "HD" for the multiplier, and possibly a "+" suffix for intermediate or taller formats, the newer, larger formats tend to be used with K notation for thousands of pixels of horizontal resolution, but may be disambiguated by a system qualifier that includes "HD", e.g. "8K UHD".
