About

Window Size Overlay is a simple yet powerful tool for web developers and designers.

Instantly see your browser window size — no need to open DevTools or use clunky inspector tools.

Just glance at the corner of your screen to view:
- the current window size (viewport or full window),
- the device pixel ratio (@DPR),
- and the exact overlay position (freely configurable).

✨ Why you’ll love it:

✅ perfect for responsive design testing
✅ live window size overlay – always visible
✅ customizable position, size and behavior
✅ lightweight, fast and privacy-safe

Works seamlessly in the background and updates in real time.
