With 5,535 reviews, y'all probably don't need mine but have offered 3 photos for size comparison in case space is very limited where you can out this thing. My mouse is a normal sized one. From front to back, mouse is a tad longer than the stand. In the widest parts of each, both are the same. If you were to stand the mouse on it's "tail" (wired version), they're also the same hight. That's just the stand though, nothing else. 3rd photo is a 12" Samsung Tab A tablet, with case on, and it's holding it very securely horizontally but fell over vertically. So, if you're going to use your tablet (12") with top of it at the top, this stand is not going to work. Watching a movie on its side is great though. My power cord should fit without trouble through the holes meant for it. For sure, 2 thumbs up and worth the $10 I paid for it (x3)!
