Pixel Winch is a screen measurement app with a unique approach. Rather than overlaying complicated controls on top of your existing workflow, it combines aspects of a traditional image editor with the quick access of a modal interface (similar to OS X's Launchpad or Dashboard).

Select a region on the screen to load it inside of Pixel Winch. The captured region will automatically magnify and center on your display. Take measurements using any combination of the included tools. When finished, simply press escape to dismiss Pixel Winch.

Need to look up previous measurements? No problem — use the history list to revisit past images. Worried about images clogging up your hard drive? Pixel Winch can be configured to automatically delete them.

It’s the best


There is no alternative

A new industry standard in design utilities.


I feel like I’ve been searching for the perfect interface-measuring tool for years. Finally, I think we have it. Pixel Winch takes a very Adobe-like approach to measuring pixel distances – I just discovered today it’s possible to drag horizontal and vertical guides from the rulers around an image. Being able to adjust color threshold on the fly, select and edit measurements, or pull up previous screenshots are all very welcome features. If you work with pixels at all – even as a developer – get this app.

Has saved me hours of tedious work


I use this app on a daily basis when working on the UI for my iOS app. Before Pixel Winch, I would copy and paste screenshots into an image editor and then use the marquee selection tool to take measurements. That was an incredibly time consuming process and the measurements weren't persistent. Now with just a few clicks, I instantly get pixel perfect measurements and can easily cycle through measurements from previous screenshots. All UI developers need this app!
