Data from September 2015 #### Classifications The mobile and tablet space is highly fragmented with reliable guarantees of support often hard to offer as device maker, browser, and OS version are each a variable in HTML/CSS rendering; With this in mind, there are three classes of mobile and tablet support: Primary support These devices represent a greater than 5% share of mobile traffic and the Web Dev team posses these devices to test against. Testing will be performed proactively for each major release (qualified as 0.1 increment in versioning, or greater). Best effort These devices represent a greater than 2.5% share of mobile traffic, and/or the Web Dev team does not have a device to test against. The Web Dev team will attempt to support these users but without physical devices to test against, cannot guarantee ongoing compatibility. Where available, simulator/emulator tools will be used to test against during each major release. Bug reports from users will be addressed, and documented in hopes of ensuring no degradation in future updates Legacy Devices that represent less than 2.5% of mobile traffic and are on the decline month-over-month. The Web Dev team does not thoroughly test against physical or emulated devices, the team will address user bug reports will be addressed, attempting a fix where it does not adversely affect performance or Best effort/Primary support devices ### Screen sizes #### Height (aka: depth) Said briefly: on desktop 60% of users can see content above the 670px line. 90% of users can see down to the 600px line without scrolling.
