Screen Ruler

Measure, inspect, and edit live webpages from a browser extension.

Meet Screen Ruler

Screen Ruler is a browser extension for inspecting and measuring webpages. Users select elements to examine dimensions, spacing, typography, colors, and the CSS rules behind the rendered interface. Side-by-side responsive views help compare layouts at different viewport sizes without leaving the page.

The toolkit also includes color sampling, asset extraction, page-weight insights, and checks for common contrast and SEO issues. Live editing lets users try CSS or text changes and review a reversible change record. MCP integration exposes supported inspection actions to compatible coding assistants, connecting visual review with the development workflow.
