Free Ruler is a lightweight screen measurement utility for macOS that displays floating horizontal and vertical rulers on your desktop. It allows you to measure distances in pixels, inches, or millimeters, making it useful for designers, developers, and anyone who needs to verify spacing and sizes on screen. The rulers can be toggled independently, moved individually or as a group, and customised with keyboard shortcuts to show or hide shadows. It is a simple, no-frills tool that stays out of the way while providing quick access to precise measurements.
AI Recommendation
1 suggestionA native Apple Silicon (Universal Binary) build of Free Ruler has been confirmed running on real Macs in the Rosetta Check community. Anyone still running an older Intel-only build under Rosetta should update to the latest version to get the native build, which will use less CPU and battery on M-series Macs. You can download the current version directly from Pascal's website or update through the Mac App Store, whichever you originally installed from.
