Ruler Overlay

The ruler overlay adds pixel rulers along the top and left viewport edges, with a crosshair tracking your cursor position — similar to ruler guides in design tools.

Enabling

Toggle Rulers in the control panel. Rulers are available in every mode.

What you see

  • Pixel tick marks along the top and left edges of the viewport
  • A horizontal and vertical crosshair line following your cursor
  • A position label showing x, y coordinates

In Guides mode, the crosshair also previews where guides will be placed when you click.
