720p

720p is a high-definition video resolution characterized by 720 horizontal lines of vertical resolution and a progressive scan. The typical native format is 1280 by 720 pixels, most commonly with a 16:9 aspect ratio. The “p” in 720p stands for progressive scan, meaning each frame is drawn in full rather than interlaced.

Origin and use

720p emerged in the early 2000s as part of the development of HDTV standards and quickly became a baseline HD option for broadcasts, streaming, and video content. It is commonly labeled as HD-ready and is favored when bandwidth or device capabilities limit higher resolutions. Because it uses fewer pixels than 1080p, 720p generally requires less bandwidth and processing power, making it practical for online streaming, live broadcasts, and older display hardware.

Frame rates and compatibility

720p content can be produced and displayed at a variety of frame rates, with 60 Hz (commonly referred to as 720p60) prevailing in regions using 60 Hz mains, and 50 Hz or 59.94 Hz in others depending on regional standards. Modern devices—from televisions and computer monitors to game consoles and streaming boxes—typically support 720p playback and can upscale or downscale content to suit display capabilities.

Comparison and considerations

With a total of about 0.92 megapixels per frame, 720p offers lower resolution than 1080p, which has about 2.07 megapixels. This makes 720p less sharp on large displays, though it can provide efficient, smooth motion due to its progressive format. Today, 720p is less common as a primary delivery format but remains used for bandwidth-constrained streaming, legacy broadcasts, and certain gaming or mobile contexts.
