What is 360p?
360p denotes progressive video with 360 vertical pixels. For 16:9 content it is commonly encoded at 640x360, although the horizontal dimension can vary with aspect ratio.
How 360p works
The 360p label identifies vertical sampling and progressive presentation, not a unique width, frame rate, bitrate, or codec. A 16:9 rendition normally uses 640 horizontal samples, while differently shaped content can retain another width. Within a delivery ladder, this tier trades spatial detail for lower transfer and decode demands, making preprocessing choices such as scaling filters and text legibility especially consequential.
Key facts
- The “p” means complete frames are presented progressively rather than divided into interlaced fields; it does not identify frames per second.
- A 640×360 raster is exactly 16:9 with square pixels, but calling any asset 360p does not by itself prove that its pixels are square or its width is 640.
- Fine captions, interface captures, and thin line art can become unreadable after reduction, even when photographic scenes remain recognizable at the same resolution.
When 360p matters
Include a 360p rendition as a fallback for constrained mobile networks or small displays. Its lower data demand reduces buffering, but text and fine detail may become difficult to resolve.
