Pixel Winch is a screen measurement app with a unique approach. It combines aspects of a traditional image editor with the quick access of a modal interface (similar to macOS's Launchpad, Mission Control, 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.

View the Quick Guide for comprehensive details about each tool.

Download the Trial to try out Pixel Winch. The trial includes all features, but also includes a gratuitous delay when loading each screenshot.

Use the Grapple Tool to quickly measure solid color and gradients. Click to measure a solid color. Click and drag-up to “power up” the grapple and measure a gradient.

Use the Rectangle Tool to draw rectangles on top of the captured image. Rectangles display their measurements and can be moved or resized. They also stop grapples, allowing quick measurements around complex shapes.

Click and drag from either ruler to place horizontal or vertical guides. Use them alone to perform quick alignment checks, or use them in combination with grapples for complex measurements (especially those involving text baselines).

Pixel Winch includes standard tools found in most image editors. The Zoom Tool magnifies the canvas up to 6400% while the Hand Tool enables fast panning. Use the Marquee Tool to copy parts of the image and the Move Tool to select and move existing shapes.
