The measuring tool in the glyph preview pane allows you to take very precise readings of your shapes. Draw measuring lines with click + drag in the preview.

  • Hold down shift to constrain to horizontal or vertical.
  • Press option to keep the previous measurement line.
  • Adjust a measurement line by dragging end markers.
  • Measuring is available in the sequence layout (command 1) of the preview pane.
  • Drag in the design space and see the measure lines update live, so you can precisely find the right value.

Note: kernpairs in the glyph preview will cause the measure line to switch back (in a negative kern) or jump forward (in a positive kern).
