ZeScreenRuler (widely known across developer repositories as ScreenRuler) is a lightweight, highly configurable open-source measurement tool built to help designers and frontend developers achieve pixel-perfect accuracy directly on their desktops.
These five core features streamline layout inspection, UI testing, and asset asset alignment: 1. Multi-Unit 2D and 1D Measuring Scales
The tool breaks away from rigid single-axis limitations by offering flexible measuring scales:
Two-Dimensional Mode: Renders a rectangular boundary box to measure both width and height simultaneously.
One-Dimensional Mode: Switches seamlessly to a standalone horizontal or vertical ruler.
Versatile Units: Instantly toggles between pixels, centimeters, inches, points, and percentages to match any project format. 2. Auto-Measurement of Active Windows
Instead of manually stretching the bounds of your ruler to fit a specific layout, the software features an automated structural detection system. It automatically detects and calculates the exact size of active windows or application boundaries on your screen with a single click, saving massive amounts of manual adjustment time. 3. Custom Marking Lines & Proportional Guides
Aligning elements to precise structural layouts is simple using built-in guide overlays:
Arbitrary Markings: Add an unlimited number of custom marking lines across the ruler canvas to flag layout boundaries.
Smart Ratios: Instantly auto-mark structural break-points like the exact center, thirds, or the golden ratio. 4. Advanced Geometry Calculations
Beyond basic box dimensions, the tool computes angular data on the fly. It can automatically measure triangle hypotenuses and precise layout angles, making it an essential utility for verifying diagonal canvas elements, CSS slant transforms, and custom vector shapes. 5. Pure Portability & Fluid Keyboard Controls
Designed to integrate directly into active developer workflows without adding system clutter:
No Installation Needed: Operates as a fully portable utility that executes instantly from a zip folder without modifying registries.
