Pixel Ruler – Measure Pixel Distances and Element Sizes Directly on Screen
Pixel ruler enables measuring pixel distances and element sizes directly on screen. Useful for web developers and designers who want to check element dimensions without developer tools.
The tool displays a movable ruler element for measuring any area in pixels. Also supports copying coordinates as CSS values.
How to accurately measure element sizes on web pages?
Quickest way: browser developer tools (F12) show element dimensions automatically on hover. Pixel ruler is useful when you want to measure elements without code or when comparing design to implementation.
