Resolutions

Resolutions

Standard	Class	Resolution	Pixels	Aspect Ratio	Notes
MMS-Small	96p	128×96	11,520	4:3	Lowest size recommended for use with 3GPP video transmitted by MMS to/from cellular phones, matching resolution of smallest generally used color cellphone screen.
QQVGA	120p	160×120	19,200	4:3	Used with some webcams and early colour-screen cellular phones, commonly used in early desktop computer and online video applications. Lowest commonly used video resolution.
QnHD	180p	320×180	57,600	16:9
QCIF Webcam	144p	176×144	25,344	11:9	Approximately one-sixth analogue PAL resolution (one-half horizontal, one-third vertical). Also the size recommended for "medium" quality MMS videos.
YouTube 144p	144p	256×144	36,864	16:9	One tenth of 1440p. The lowest resolution on YouTube.
NTSC square pixel	240p	320×240	76,800	4:3	Comparable to "low resolution" output of many popular home computers and games consoles, including VGA "Mode X". Used in some webcams and for video recordings in early/budget digital cameras and cameraphones, and low-end smartphone screens. Original YouTube resolution. Maximum recommended size for "large" MMS videos.
SIF (525)	240p	352×240	84,480	4:3	NTSC-standard VCD / super-long-play DVD. Narrow/tall pixels.
NTSC widescreen	240p	426×240	102,240	16:9	Same as current YouTube "240p" mode; screen resolution of some budget portable DVD players. Roughly one-third full NTSC resolution (half vertical, two thirds horizontal).
CIF, SIF (625)	288p	480×272	130,560	4:3	PAL-standard VCD / super-long-play DVD. Wide/short pixels. Also a common resolution in early webcam / video conferencing, and in advanced featurephones and smartphones of mid-2000s (ca 2006).
PSP	288p			30:17	Notionally 16:9 with slight left/right edge cropping. Used in many portable DVD player screens and other small-format devices besides.
360p	360p	480×360	172,800	4:3	Uncommon, used in some lower-mid-market smartphone screens and as an intermediate screen resolution for some 1990s videogames.
Wide 360p	360p	640×360	230,400	16:9	Current base resolution in YouTube, labelled as "360p". The lowest and least computationally demanding resolution supported by hardware able to run mainstream desktop operating systems;[vague] the lowest interruption-free resolution with low-end broadband connections. Typically used as the base "SD" standard by VoD services due to subjective similarity (and similar pixel counts) to a mid-grade free-to-air broadcast picture. Effectively, the resolution offered by any higher-definition 16:9 video scaled down for a standard 640×480 (VGA) computer screen. Offers 75% of the pixel count of a true anamorphic NTSC DVD image, or 89% of a letterboxed 16:9 image. Historically used as an ad-hoc standard for intermediate-quality / CD-R-sized MPEG4 conversions on P2P file sharing networks.
