Screen Ruler
Screen Ruler freezes your screen and lets you measure anything on it in real pixels: a button, an image, the gap between two elements.
Use it#
- Press Super+Shift+R, or click Open Ruler on the page. The screen freezes and fills the display.
- Drag to measure a rectangle. Its width and height in pixels are shown as you drag.
- Hold Shift while dragging to measure a straight line instead.
- Press Ctrl+C to copy the measured size to the clipboard.
- Right-click to clear the measurement and measure again.
- Press Esc to close the ruler.
Controls#

| Ctrl+C | Copy the measured size |
| Right-click | Clear the measurement |

Accuracy#
Measurements use screenshot pixels, including on high-density displays, so you measure what is really drawn, not scaled units.
