PixelSnap

PixelSnap measures the size of objects and the space between elements across apps. Drag an area around an object to detect its boundaries, or measure several objects at once. You can keep dimensions visible on the screen and copy measurements to the clipboard.

Horizontal and vertical guides snap to screen elements and show the distance between guides. A crosshair mode helps check alignment, while adjustable tolerance helps detect elements with shadows or low contrast.

You can save a selected area with its measurements as an image, with CleanShot integration available for screenshot workflows. Integrations with Sketch, Affinity Suite, and Figma show actual dimensions regardless of the displayed zoom level.

PixelSnap supports Retina screens and multiple displays. A customizable global hotkey opens the tool, and other keyboard shortcuts can also be changed.
