Best Tools for On Screen Measurements? - dobag - 07-24-2025
Hey everyone,
I often find myself needing to measure elements directly on a web page, like checking pixel spacing, dimensions, or alignment. I'm currently searching for a reliable browser ruler app that works well across different browsers and offers precision.
I’ve tried a few extensions, but some are either outdated or clunky. Ideally, I’d love something lightweight, easy to toggle on/off, and accurate enough for UI/UX design tasks. Does anyone here use a ruler tool they’d recommend? Any specific features I should look for?
Appreciate any suggestions or links, thanks in advance for your help!

For someone working on UI/UX design and needing precise measurements directly on web pages, here are some excellent ruler and measurement tools (mostly as browser extensions or apps) that are widely recommended by designers and developers:
✅ Top Browser Ruler Tools (2025-relevant and actively maintained)
1. PixelSnap 2 (Mac Only)
- ? Most accurate and designer-loved tool
- Features: Instantly measure distances between any onscreen objects, smart guides, snap to edges.
- Use Case: Desktop-level precision for any UI designer (great for Figma/Sketch + browser).
- Website
2. Page Ruler Redux (Chrome, Firefox)
- ? Rebuilt from the older “Page Ruler” extension.
- Features: Drag-to-measure, shows width/height, position, resizable box.
- Pros: Open-source, lightweight, actively maintained.
- Chrome Web Store
3. MeasureIt! (Firefox)
- ? Simple and fast.
- Features: Click-and-drag to draw a ruler on any page. Good for quick checks.
- Firefox Add-on
4. CSS Peeper (Chrome)
- ? Great for devs/designers inspecting styles too.
- Features: Inspect element spacing, typography, colors, and dimensions without digging through dev tools.
- CSS Peeper
5. Dimensions – by Marko Dugonjić (Chrome)
- ⚡ Measure between elements by hovering.
- Use Case: Super fast pixel spacing checking between objects.
- Chrome Extension
? Features to Look For in a Good Ruler Tool
- ✅ Pixel-accurate measurement
- ✅ Snap to edges or UI elements
- ✅ Keyboard shortcuts for toggle on/off
- ✅ Cross-browser compatibility (at least Chrome & Firefox)
- ✅ Lightweight UI (not cluttered)
- ✅ Optional grid overlay or alignment tools
? Bonus Pro Tip:
If you are working with Figma or Sketch, they have built-in measurement tools with keyboard shortcuts that can replace browser rulers for mockups and designs.
