The 'Browser width - bucketed' dimension shows the width of the browser window, classified in groups of 100 pixels. This dimension is useful when you want to understand how wide visitors see your content. Understanding how wide your content is typically viewed can allow you to optimize content for viewing.
This dimension is different than screen width. Browser width is the number of pixels within the viewable browser space, while screen width is the width of the entire monitor in pixels. If you would like to see the difference between these two variables on your own machine, open the browser console (F12 on most browsers) and copy + paste the following code into the console:
"Browser width: " + window.innerWidth + " pixels\nScreen width: " + screen.width + " pixels";
Browser width is always smaller than or equal to screen width, since browser width doesn't include scroll bars or borders.
Populate this dimension with data
Adobe persists browser width for a visit. If browser width is adjusted mid-visit, the adjustment is not recorded.
