While simply pasting in generic user interface (UI) elements is the wrong way to complete any design, there are a few really good reasons for why designers should keep PSDs of UI kits handy.

For one, the best UI kits feature exemplary work that can become a great source of inspiration. Learning from the work of others is one of the best ways to grow as a designer. Secondly, if you haven’t done much UI design before, these kits serve as a proper starting point. Lastly, having high quality UI elements at your fingertips makes it easy to quickly build impressive mockups for clients while ideas are still fresh.

Clearly, there’s some real benefit to keeping these UI designs nearby, so we’ve done the dirty work for you and gathered our favorites together. Without further ado, I present to you this list of 13 high quality, free PSD UI kits for designers:
