Video Resolutions Used in Videoconferencing and Video Streaming (Q123)

The information in this article applies to: H.320,H.323,H.325,SIP,RTP (RFC 3550)

As a matter of convenience, people working in the videoconferencing space often refer to display sizes using a shorthand name for the video display resolution. We refer to that as the display "mode name" in the tables below.

These tables are intended to serve as a quick reference guide. Even those who are experts in the field often forget how many horizontal pixels there are for each of the various modes. Thus, we felt this would be a handy page for everybody.

Below are most of the more modern display modes:

Mode Name Resolution
90p 160x90
180p 320x180
240p 352x240
360p 640x360
720p 1280x720
1080p 1920x1080

Below are the wide-screen and standard PC screen resolutions:
