Bigger than anticipated! I think the size will be okay once I decide which side to place it on! I have an under mount kitchen sink (which I hate!) so it sits lower than I wanted. Will replace the sink!!! LOL Suction works great! 4 cups.  I think it would be perfect for a farmhouse sink, a deeper/larger sink or an above counter sink. (I haven't measured my sink, but I believe it is smaller than an average kitchen sink, more apartment size (cheap construction)). I say go for it because it is a solid piece/great price and its made by Simplehuman!
