In this web content, Set Studio discusses the importance of considering the fragmentation of screen sizes and browser viewports when making design decisions. They conducted an experiment and gathered over 120,000 data points from users in the USA and Europe. The top viewport sizes were primarily small, which could indicate mobile devices. They also explain that when measuring viewports, a width greater than 800px is considered a “large viewport” rather than a desktop screen size. The main point is to emphasize the need for flexible rules and allowing the browser to determine the best outcome based on its conditions. Set Studio recommends simplifying content and embracing the lack of control over how websites are visited.
