The Dimension tool lets you measure and plot dimensions such as distance, angle, and radius in your artwork. 

See the Dimension tool in action, measuring & displaying the linear, angular, and radial dimensions of a package design in Illustrator.

  1. Select the Dimension   tool. 

  2. Select a dimension type from the taskbar that appears:

    Linear Dimension   :

    • To plot a linear dimension, hover over any path segment and drag the cursor outwards.
    • Alternatively, you can choose any two points on your canvas and measure the distance between them.

    Angular Dimension   :

    • To plot an angular dimension, hover over any angle and drag the cursor outwards. 
    • Alternatively, you can choose any two points on any two intersecting lines and measure the angle between them.

    Radial Dimension   :

    • To plot a radial dimension, hover over any circle or perfect arc and drag the cursor outwards.

  3. Select Tool Options   from the taskbar to modify unit of measurements, scale, precision, and appearance of your dimension objects.
